Towards the end of last year, I recorded this interview with success coach, Georgia Bamber. Georgia shares with us just what it is a life coach does, along with some little nuggets of wisdom on how to audit your life and leverage the power you have within you. This year could be your best running year yet!
Watch the interview, and download Georgia’s Life Audit Workbook. It’s a great tool to get you started on leading a very purposeful life. Could be just what you need to get you on the road to your next PB!

Myth One: If you don’t have clear wee you are dehydrated.
The fact of the matter is, if your wee is clear, you are likely over hydrating, or you may have kidney problems, diabetes, or other health issues.
Your body is very clever. It can defend itself against dehydration by changing the amount of water it retains. If it is retaining water, then your urine will be darker in colour. And if your urine is darker in colour because your body is retaining water, that can be a good thing. It means your body is working well to remain hydrated. Conversely, if you have more fluids than your body needs, it will rid itself of the extra water in your urine, making it less concentrated. The more we drink, over and above what our needs are, the more we wee, and the clearer our wee will be. Studies that have looked at blood markers of hydration have found the colour of your wee does not necessarily correlate with dehydration (that is, a blood sodium level of over 145 mmol/L.
As far as wee colour goes, something not clear, and not dark as tea, is where you want to be (as long as you have no medical conditions which will effect your hydration status). If you do have persistently dark wee, or persistently clear wee which can’t be explained by the amount you drink, you should see a doctor.
Myth Two: If you don’t drink water during a race, your performance will suffer
Used to be, people would say if you wait until you’re thirsty to drink, it’s too late-you’re already dehydrated and your performance has already been impaired. It seems that the body can cope much better with temporary dehydration than was previously thought. Taking water on board based on how you feel is more important than replacing every drop of fluid you use.
A couple of recent studies highlight this well.
One study had 23 female recreational runners do two 15km time trials, in mild, but humid conditions (68 degrees F/ 20 degrees C, 87% humidity). In one of the trials, they drank 12 oz of water during the run (about 350mls), and in the other they simply rinsed their mouths with water and spat it out, every 3kms.
The results were interesting. The time trial results of the two groups were pretty much the same – the drinking group averaged 79.8 mins and the mouth wash group averaged 79.7 minutes for the 15k. The drinking group sweated more, and the mouthwash group felt thirstier after the run. The study also looked at a group of responses called “affective responses”, which looked at things like pleasure, arousal, energy, calmness and tension. Again, the responses were fairly similar on most measures, but the mouth wash group did report more tension.
So, under these conditions the runners didn’t need to consume water to maintain performance. Note that the temperature was fairly mild. It’s not at all unusual in Australia to be running in much hotter temperatures. I’m not suggesting you shouldn’t drink if you feel like you need to. I am suggesting that we don’t need to drink as much as we think we do, and if your gut feels like it can’t handle any more water, you could just try rinsing and spitting instead. You might actually be better off pouring the water over your head to cool you off!
A 2010 study (sponsored by gatorade) compared runners over a series of four trail runs. One group drank 200mls of water in the 22 hours prior to the runs, and no water during the runs, and the other group went into the runs well hydrated, and drank during each run. The results showed impaired performance for the non drinkers. Note that these runners with impaired performance started the run already dehydrated, as compared to the other studies which were done with runners who had normal hydration levels prior to the experiment.
Myth Three: Loss of body weight during a run means you are dehydrated and your performance suffers
Changes in body weight when you are exercising hard are not only caused by fluid loss. You burn fuel when you run, and when that fuel is used up, then you weigh less. As your race or training run progresses and you use up stored carbohydrate and fat your weight will drop. Not only that, as you burn calories during your run, you’ll also be liberating some water, which becomes available to you body. Another fact to consider is that as you lose body weight during a run due to fuel burning and fluid loss, your lighter weight will enable you to run faster – up to a certain point of course. You don’t want to deliberately dehydrate yourself in a bid to lose body weight to help you run faster! I’m just saying that all these little things add up to going some way to explaining why reduced body weight is not the best predictor of performance. The purpose of drinking during exercise is to keep your blood plasma levels stable, not to keep your body weight stable.
A 2016 study had well trained athletes run a 20k time trial in the heat. One group drank as much as they wanted to during the run, the other drank a set amount of fluids based on pre-determined individual needs, designed to replace as much of their sweat loss as possible.
The “drink when you want” group lost 2.6% of their body weight, whilst the well hydrated group lost only 1.3% of their body weight during the time trial. As you’d expect, the group who were drinking deliberately lost less body weight than the “drink when you want” group. Nothing to see there. But here’s what’s interesting. The performance of the groups was very similar. The hydrated runners averaged 1:44:39, and the “drink when you want” runners averaged 1:44:09. There was no difference in core temperature between the two groups at any point.
Haile Gebreselassie, one time marathon world record holder and all out running legend lost 9.8% of his body weight when he won the Dubai marathon in 2009. One study looked at the fluid intake of 9 major city marathon winners, and 1 second place getter. It showed a body weight loss of between 6.6% and 11.7%, including including Gebreselassie’s 9.8% loss in 2009. Seems you can get some pretty good results, even if you lose quite a bit of weight during a race!
A Few Tips on Hydration
Drink water when you are thirsty, all of the time, not just when you are running. That way you’ll go into a run well hydrated.
For runs of 60 minutes or less, it seems you probably don’t need to drink much, if at all, unless the conditions are hot and humid. What feels “hot and humid” to you will depend on the weather conditions you are used to running in, your age, and your body size and composition.
Experience will help you find the ideal hydration strategy for you. Around 500mls of water each hour once your runs are longer than 60 mins is a good starting point.
Drink when you are thirsty during your run – water availability permitting. You might find you have to be a bit flexible on this if you are not carrying water with you.
Choose a route where you know there will be water available to you, or do a loop course and stash a water bottle somewhere, or leave it in your car.
If you plan to carry fluid with you in a race, it’s a good idea to train with what you are going to carry to get used to how it feels.

Inflammation. At its worst, it can stop you in your tracks. But if your tendency is to reach for the Voltaren at the first slight twinge or sign of inflammation, you might like to consider what purpose inflammation actually serves…
And you also might like to consider that Volaren, Ibiprofen and other Non Steroidal Anti-Inflammatory Drugs (NSAIDs) can limit the benefits you gain from training!! Sometimes it’s tempting for runners with a niggling injury to take anti-inflammatories to get them through their key long runs leading up to a race, but studies have shown that this can be counter-productive.
What Role Does Inflammation Play?
Inflammation is a protective mechanism your body uses to remove harmful stimuli and start the healing process. After a hard workout, specific cells are activated to increase blood flow to the muscles used in the workout. This increased blood flow also occurs in the initial stages of an acute injury. It produces swelling and stimulates the nerves that cause pain.
Inflammation is the beginning of the healing process, and it’s super important for recovering not only from injury, but from normal bouts of training as well. Without inflammation, your recovery from each bout of exercise (or from injury) would be much slower.
But what about R.I.C.E? Isn’t the idea to reduce inflammation?
Good point. The standard procedure for injuries which provoke the inflammatory response, such as a sprained ankle, is Rest, Ice Compression and Elevation. The R.I.C.E protocol is designed to REDUCE inflammation, so if inflammation isn’t bad, and it’s the body’s natural response to injury, why do we want to reduce it?
Firstly, we need to understand that the inflammatory response is non-specific. Incredible as our bodies are, we don’t seem to have evolved to be able to differentiate between the response needed to cope with a potentially deadly pathogen such as a bacteria or virus entering the body, and the response needed to help a sprained ankle to heal. The overriding function of the body is to keep itself alive. This takes precedence over all else. If a massive inflammatory response is required to neutralise potentially deadly pathogens, from the point of view of survival, it’s of little consequence that your ankle might lose some functionality due to inflammatory overkill after injury. Better to have slight loss of function of the ankle, than be dead.
One of the things inflammation does is put up a barrier around the area of infection or injury– whether that is around a sprained ankle, or around an area where a pathogen has set up house inside the body. This slows the passage of pathogens or toxic products into the surrounding healthy tissue. In the case of a sprained ankle, too much inflammation can actually inhibit the repair of the tissue. Too much swelling in the injured area might make it difficult for blood to diffuse into the cells, resulting in a lack of oxygen and further damage, so reducing the inflammation makes sense. One of the other things ice will do is slow the metabolic rate of the cells in the area, which temporarily decreases the cell’s requirements for oxygen.
Why exercise produces inflammation
When you run (or perform any other form of exercise) you create small micro tears in your muscles. The higher the intensity of the workout, the more forcefully you are contracting your muscles, and therefore the more damage you cause.
The micro-tears cause your body to set up an inflammatory response. Substances such as blood, oxygen and nutrients are shunted to the damaged area for the healing process to begin. This micro damage is not enough for the body to over-do the inflammatory response, but it can be enough to cause pain and discomfort.
When you should NOT take anti-inflammatories, and why.
If you’re interested in getting your body into the best shape possible, you shouldn’t take NSAIDs in the following circumstances:
To reduce the pain of a current injury to get you through a long run
During a race
Prophylactically – that is to prevent the anticipated pain of a sporting endeavour, or to prevent injury
NSAIDs can reduce the training effect
If you’ve got a niggling ITB, or a bout of bursitis for example, something that’s not too bad, but there all the same, it’s very tempting to pop a pill to get you through your scheduled long runs. You fear not getting in the mileage you’d intended will affect you poorly on race day. And it might…
But washing down a couple of anti-inflammatories with your pre-run hydration isnt’ the answer. A 2010 study by Japanese scientists showed that whilst anti-inflammatory drugs will indeed facilitate a longer distance run, the taking of the drug cancelled out the training effect that could be achieved from the longer distance. If you run with NSAIDs coursing through your veins, the training adaptation you could expect from that run will be diminished.
In other words, by taking the drug to enable you to run further, your body is not able to make use of the longer distance you run. You’re wasting your time. You’d be better off running within your pain threshold and gaining the training benefits from that. A longer run on NSAIDs will not see you get as fit as if you were running without NSAIDs, so you may as well run for less time and enjoy the training benefit.
Taking NSAIDS for long periods of time can have adverse effects on your gastrointestinal and cardiovascular system. These adverse effects become more pronounced with longer duration of use. Taking NSAIDS before physical activity can mask pain and cause an injury to get worse, or mask the pain of a developing injury. Anti-inflammatories may also impede the synthesis of collagen, that gives strength to tissue. Some of the chemical substances naturally occurring in the body which NSAIDS inhibit are important in the response and adaptation of muscles and other connective tissue to loads placed upon them. Taking NSAIDS can reduce the strength gains from training.
Taking NSAIDs may not reduce your perception of pain
Using NSAIDS prior to a race to prevent the pain of racing has been shown to be ineffective. This study on athletes competing in a 160k endurance run showed the ibuprofen use did not alter muscle damage or soreness. That’s right, taking anti-inflammatory drugs before the race made no difference to the athlete’s perception of pain. The perceived exertion of ibuprofen users and non-users was very similar. On the Borg scale, the control group rated their exertion slightly lower than the anti-inflammatory group (14.5 vs 14.6), and interestingly, and interestingly, Ibiprofen use was related to increased endotoxemia and inflammation.
When is it good to take anti-inflammatory drugs?
During the initial stages of an acute injury (like a muscle strain, sprained ankle, or sudden onset of an inflammatory conditions such as tendonitis or bursitis), NSAIDS are likely to facilitate healing. Taking NSAIDS for the first 2-3 days is appropriate, but after that, you may be better off letting the body’s own natural healing take over.
There are of course other circumstances when NSAIDs are necessary, but that’s best left up to your medical practitioner to decide
Lightning can contain 100 million to one billion volts. That should be enough to make you wary of running in an electrical storm (or doing any other outdoor activity for that matter).
Here are some of the non lethal effects of being struck by lightning, just in case you need further convincing.
Short term Effects
Impaired eyesight or blindness
Ringing in the ears
Ruptured ear drums
Burns to the skin
Burning to internal organs
Long term effects
Problems with sleeping
Balance problems affecting gait
The three second rule
Count the number of seconds between seeing a flash of lightning and hearing thunder. For every three seconds, the lightning is one kilometre away. And just because you don’t see lightning, don’t assume it’s not around. Apparently, you can’t have thunder without lightning (but you can have lightning without thunder)
What to do if you’re caught outside in a thunderstorm
You should always check the weather forecast and the weather radar before you head out for a run, even if it’s a bright sunny day. If you’re planning a long run, much can change in a couple of hours. If you do get caught out in a storm there are some precautions you can take.
Seek shelter, not under a tree or other tall pole-like structure. Lightning has a tendency to strike taller structures within reason, and if you’re next to a tree when lightning strikes you can either be injured by the falling tree, or be felled by the electricity conducted through the earth.
Pop into a shop or a service station until the storm has well and truly passed. A bus stop, porch, verandah or other non-enclosed structure won’t cut it. It’s recommended you wait till half an hour after the last lightning flash before you venture out again. More than half of lightning deaths occur after the storm has passed.
If you’re close to your car, you can take shelter in it, but be careful to stay away from the sides of the car. Sit in the back seat, or on the floor in the back. Keep the windows and doors closed, and make sure you are not parked under a tree!
If you can’t get under shelter, crouch over into a ball with your chin tucked in. Have two feet on the ground, as close together as possible. This makes you a single point of contact. Don’t lie on the ground.
If you’re in a group, stay several metres from each other.
Keep out of puddles, as water conducts electricity
Don’t put up an umbrella. And if you have an umbrella with you when you’re running, you have other issues!
Some other points about electrical storms
Lightning does, and often strikes twice.
Someone who has been struck by lightning will not contain a residual charge from the lightning, and you can safely perform first aid on them
If you’re inside, stay away from concrete walls or floors which may have metal bars inside them
Do not have contact with anything that can conduct electricity (e.g., electrical equipment or cords, plumbing fixtures, corded phones)
Running in wet weather
If you’re sure there is no electrical activity about, there’s no reason you shouldn’t get out and run in the rain. Here are some tips for wet weather running.
Anyone who’s ever done regular physical exercise, whether that be running or something else, knows how good exercise can make you feel. But did you know that vigorous aerobic exercise actually triggers the birth of new neurons in the brain. And what’s more, to date, vigorous aerobic exercise is the only known trigger for the birth of new neurons!
Vigorous aerobic exercise such as running has been shown to have positive effects on the structure and function of the brain, namely generation of neurons in the hippocampus, the part of the brain important for learning and memory. By vigorous, I don’t mean flat out. You’re looking more at something that makes you puffed without feeling like you can’t continue.
Changes have also been seen in the frontal lobe of the brain of people who have been long term exercisers, with an increase in blood flow to this area. This is the part of the brain which is associated with clarity of thought – stuff like planning ahead, concentration, time management, goal setting and learning. This area is also linked to the regulation of emotion, hence, going for a run just seems to make you feel good.
Aerobic training more effective than HIIT and resistance training
A study by researchers at the University of Jyväskylä looked at the effect of sustained running exercise, high intensity interval training (HIIT) and resistance training on the production of neurons in adult male rats. The study also looked at groups of rats that had either a genetically high response to aerobic training, or a genetically low response to aerobic training. Groups of rats were put on an exercise program for 6-8 weeks, and a control group sat on the couch in their regular cage.
The highest number of new neurons in the hippocampus was found in the rats on the long distance training program, and who also had a genetic predisposition to benefit from aerobic exercise. Compared to the couch potato rats, the runners had 2-3 times more new neurons at the end of the experiment period. The body building group of rats who were put on a resistance training program showed no improvement in neurogenesis, and the HIIT group showed only minor improvement.
Marked cognitive decline in old age is not inevitable
The decline in our ability to think clearly is commonly considered to be a characteristic of aging. But not everyone experiences cognitive decline to the same degree. There are vast individual differences in the ability of the brain to function in old age. Could aerobic exercise be what’s allowing some people to maintain good cognitive function, whilst the brain function of others fades, sometimes dramatically?
A study published in the Journal of Gerontology in Nov 2006 randomly assigned older adults to an aerobic exercise group or a non aerobic exercise control group for six months. The subjects who participated in the exercise program had an increase in both grey and white brain matter mostly located in the regions of the brain which show substantial age-related deterioration ( the prefrontal and temporal cortices)
Neurons are found in the grey matter of specific brain regions, whilst white matter enables the communication between brain regions. They work together to enhance brain function, so the fact the aerobic exercise benefits both grey and white matter is the main reason it ranks so highly as a way to keep your brain young.
What’s going on inside your noggin to produce these changes?
Scientists at the Harvard Medical School isolated the specific molecule which improves cognitive function and protects against brain degeneration. The molecule, which has been named irisin, is produced in the brain during aerobic exercise through a chain reaction.
Firstly, a molecule called FNDC5 becomes elevated. Irisin is a byproduct of FNDC5. Increasing levels of irisin in the blood forces irsin to cross the blood brain barrier. That then increases the production of brain-derived neurotrophic factor (BDNF). Increasing levels of BDNF stimulates the growth of new neurons.
How much do you need to run to get the benefits?
Firstly, you probably don’t need to run. Any aerobic exercise of a moderate to intense nature will do it. One study conducted by Justin Rhodes at Oregon Health and Science University found that the BDNF concentration in mice increased by up to 171% after 7 nights of wheel running. Initially, the more running, the more BDNF, the greater the neurogenesis.
After a while, Rhodes found that his ultra-marathon mighty mice, who crazily ran all day and all night, eventually were unable to navigate a maze successfully. He found the best performing mice ran two to three miles a night. As they say, “everything in moderation”.
( I’m not sure what that equates to for humans, but in the course of trying to find out, I did discover that “mice miles” refers the amount of time one spends at a computer).
If you’re not already doing some at least moderate aerobic exercise, and you want to improve your thinking power, then start moving. Long easy runs, faster tempo runs, fartlek, interval training will all help to improve your brain power. (Note high intensity interval training -short bursts of all out effort, will do little to improve your cognitive function, but the the sub-maximal efforts more commonly part of a distance running program will)
Or put another way, how long is a piece of string?
I was chatting with one of our runners the other day, who was concerned that her average heart rate was too high during a recent race. I’m not qualified to answer such a question as it relates to a particular individual and their heart health, but my general feeling was that an average heart rate of 172 beats per minute over a 5km race was not too high. However, if you have any concerns regarding your health, particularly the health of your heart, you should consult someone who is qualified to assess you. And I am not.
So, that’s the disclaimers out of the way. Let me also say, that our training programs are based on pace and intensity level, rather than heart rate. There are too many variables when it comes to heart rate, so it is not the most relevant factor when it comes to determining how hard you can or should race and train. There are many things which can effect your heart rate from day to day, such as sleep and stress levels, just to name a couple.
To race fast, you need a high average heart rate during the race
A relatively high average heart rate during an exercise bout shows a greater capacity of your heart for work. A greater work capacity of your heart is one of the things which will make you able to run faster, and in a race, that’s the goal.
When you increase your speed (and therefore your intensity), your muscles need more oxygen. If your heart has become stronger through training, it will be able to beat faster to get more oxygen and nutrient containing blood to your working muscles. You can’t run faster without your heart rate increasing.
Low Average Heart Rates and Fitness levels
There seems to be a misconception that high heart rates are bad, and being able to maintain a lower heart rate during racing or training means you’re fitter. Through training, you improve your movement economy, your running efficiency. That means at any given pace, your average heart rate will decrease as you become fitter. In other words, as you become fitter and your running economy improves, you don’t have to put as much effort in to run the same pace. Conversely, at any given heart rate, you’ll be able to run faster.
But, more often than not, the goal of a race is to either run as fast as you are capable of, or to beat everyone else in the race-or beat your friends at least. Your goal is not to run with a low average heart rate. A higher average heart rate means your heart is fit enough to have the capacity to work harder, and therefore run faster.
Your exercise performance is regulated by your cardiac output. Cardiac output is the amount of blood the heart pumps through the circulatory system in one minute. At rest, your total blood volume (which is generally between 4 and 6 litres, depending largely on your size), is pumped through your heart once. During exercise, the amount of blood pumped by your heart can more than double in a reasonably fit person. In elite athletes, the heart can pump around 6 times as much blood through the circulatory system each minute.
Cardiac output is influenced by two things: stroke volume and heart rate.
Stroke volume is the amount of blood ejected by the heart in one pump, and heart rate is the number of the number of times the heart beats per minute. Increase either or both of these, and you increase cardiac output.
The more active your muscles are, the more oxygen they require. When you start exercising, your muscles signal your hear to pump faster which increases the blood flow. Your working muscles increase stroke volume by contracting and sending larger volumes of blood back towards the lungs where it can be oxygenated and pumped out by the heart again to deliver oxygen back to the working muscles.
Adaptations to Training
As you undertake a training program and get fitter, your cardiac output increases. Your heart, which after all is just another muscles, gets stronger and is able to pump faster, and to pump more blood due to its improved strength, and the improved ability of the working muscles to help deliver deoxygenated blood back to the lungs to be re-oxygenated.
Does your maximum heart rate increase as you get fitter?
Your potential maximum heart rate is probably not very trainable, but your ability to reach your maximum heart rate may be. The whole thing is very hard to measure. To exercise at your maximum heart rate is not a particularly comfortable experience. You basically need to push harder and harder until you’re a blithering mess and can’t tolerate any more. But what’s to say the put at which I might give up, the level of pain I can tolerate, or the level of motivation I have to keep going, is the same as the next persons, or will be the same for me on each occasion I were to undertake such a test?
It’s often reported that as people get fitter, their maximum heart rate decreases, rather than increases. This is most likely due to the improvements in stroke volume as they become fitter. The heart is able to pump more blood each beat, and therefore does not need to pump as fast to deliver blood to the working muscles. It may also have something to do with psychological factors involved in testing.
Maximum heart rate is not the determining factor when it comes to running faster
When it comes down to racing, it’s not the person with the highest maximum heart rate who’s going to run the fastest. It’s far more likely to be the person with the highest average heart rate, or close to it. The person who can maintain a high heart rate for the longest amount of time, will be the person who is able to deliver the most nutrients and oxygen to the working muscles, allowing the muscles to work harder, and allowing the runner to run faster.
Would you eat 20 chicken nuggets, 12 Paddle Pops, or 5 bowls of fruit loops in one sitting? Probably not, but you might drink 4 gin and tonics, or 4 bourbon and cokes at your next Christmas party. And the amount of calories they yield is around about the same.
Add to that the extra snacks we all tend to eat along with alcohol, you might be taking on board a whole extra day’s worth of calories in one Christmas party if you’re not careful.
But as a runner, you don’t want to pile on a couple of extra kilos at Christmas time, only to have to carry it round the course with you in your next event. So what to do?
The answer is definitely not to stop partying!!
Five tips to help minimise the impact of all that Christmas cheer.
Plan to have only a few days on which you really overdo it
On Christmas morning, go for a medium length run (60 minutes or more) and a moderate intensity, and include some faster efforts.
Do daily bouts of vigorous activity
Exercise within 1 hour of eating your big Christmas dinner
Don’t pig out on treats like Christmas chocolates, just to “get rid of them”, or “get them out of the house”
And if you’d like to know more of the science behind why following these simple guidelines will work, read on.
Plan to have only a few days on which you really overdo it
If you’re going to overeat, do it properly. Really satisfy your desire for gluttony. Eat like a pig once or twice and be done with it. You’re far more likely to be able to resist those extra dips and chips and other stuff people offer you if you know you’ve already had a blow out. You won’t feel so much like you are depriving yourself.
Eat less at the meals you aren’t planning to really go for it. And definitely don’t have two blow out days in a row. Your body can handle some extra calories occasionally, but if you don’t have a break from overindulging, the extra energy just won’t be used up.
On Christmas morning, or before any planned pig-out, go for a 60+ minute medium effort run and include some efforts at a higher intensity
The aim here is to deplete your muscles of glycogen before you eat. If you can manage to get this workout in before you eat breakfast, all the better.
When you eat, carbohydrate is broken down into simple sugars, moves into the bloodstream, and insulin is used to shunt the sugars out of your blood. From the blood it is used by the brain, stored in the liver, and stored in your muscles in the form of glycogen. Once these storage areas are full, then it is stored as fat.
So, if you deplete your muscles of glycogen before you eat, there’ll be more room in the muscles to store the glycogen from the carbohydrate that you eat. It’ll be stored here ready to be released next time you need energy. If your glycogen storage silos are already full when you start eating, then more of the carbs you take in will be store as fat.
If you know you’re going to be eating a big meal on Christmas day, it would be ideal to go for a run on Christmas morning, and then eat very little, or not at all, until the main event. If you can’t get out on Christmas morning, go out as late as you can on Christmas Eve, and eat very little till your main meal on Christmas day.
Do daily bouts of vigorous activity
Overeating and inactivity is associated with alterations in the expression of certain genes in fat tissue. Unfortunately, it’s also associated with the holiday period!
Research published in the Journal of Physiology in December 2013 showed that daily vigorous exercise bouts could counteract the effect of short term overeating and under activity, with respect to alterations in gene expression and the effect this has on metabolism.
This applied even though the vigorous activity undertaken by research participants meant they had a positive energy balance – ie they still took more calories in than they expended in exercise. The groups ran on a treadmill for about 45 mins at about 70% of their maximum capacity, so it was quite vigorous exercise for a reasonable period of time, but if you have the fitness under your belt to be able to do that, go for it. Even if you can’t manage a 7/10 effort for 45 minutes every day, doing some vigorous activity on most days is going to help keep your waistline trim.
Exercise within an hour or two of eating your big Christmas dinner
If you’re planning a Nanna nap on Christmas afternoon, think again. Once you’ve taken in all that extra energy, you want to use as much of it as you can whilst it’s still circulating in the blood stream, and before it gets shunted into the body’s long term storage silos – adipose tissue, more commonly known as fat.
Researchers at Oxford University found that after a large meal containing 30gms of fat, two to three teaspoons of fat can be added to the waist very quickly. The first fat from any meal enters the blood about an hour after you eat. After around three hours, most of that fat has been incorporated into adipose tissue around the waist. Pretty much, the fat circulates in the blood stream and is “caught” opportunistically by the fat cells around the waist – if fat is floating past in the circulating blood, it’ll be nabbed by the fat storage cells around the waist. Then if it’s not used quickly enough, the fat isn’t mobilised for energy, and goes into longer term storage around hips and bum.
A game of backyard cricket, a trip to the beach, or a long walk will serve you well if you’re trying not to put on extra weight. This post meal exercise can be lower intensity-as your body will prefer to use fat for energy at a lower intensity – which is a bit of a bonus. Who wants to work hard with a tummy full of Christmas pud?
Don’t pig out on treats like Christmas chocolates, just to “get rid of them”, or “get them out of the house”
Let’s be real here. Chocolate doesn’t fill you up-it just makes you feel good. It’s not going to stop you from being hungry for the rest of the day. If you eat all your Christmas chocolate at once, just because you want to get rid of it and then start being “good”, chances are, you’re not going to take in less calories at the next meal to counterbalance the extra calories from the chocolate.
Eating an extra 500 calories from any food source, in any one day, is likely to put you into energy excess, and that’s how you put on weight. Much better to have one or two chocolates a day until they’re finished, or just chuck them out. There’s no rule that says you have to eat something just because it’s there!
