Why exercising may not help you lose weight – The Independent

It is often said that the secret to losing weight is as simple as burning off more energy than youre putting into your body. And by that logic, you should be able to shift some pounds by hitting the gym -provided you're not eating lots more than you were before.

But there may also be some truth in the saying that you cant outrun a bad diet, as many people whove been pounding the treadmills for months without seeing any results will be able to attest.

As everyone (well, perhaps everyone except Donald Trump) knows, regular exercise does wonders for your mental health and general wellbeing, and its also been linked to longer life expectancy and reduced risk of heart attacks, diabetes and dementia.

However, increasingly research is showing that exercising wont help you lose weight nearly as much as most people think.

People expect exercise to be a great way to help them lose weight, but the effects on weight are only small, says Dick Thijssen, a professor in cardiovascular physiology and exercise at Liverpool John Moores University.

Some studies have shown that working out raises your base metabolic rate which means you burn more calories over the course of the day, but according to Professor Thijssen, if you exercised for three or four months without changing your diet, youd only lose about 1kg.

According to the Mayo Clinic, a not-for-profit medical research establishment in the US, in general, studies have demonstrated no or modest weight loss with exercise alone and that an exercise regimen is unlikely to result in short-term weight loss beyond what is achieved with dietary change.

In 2012, a study by US researchers provided a breakthrough on the subject. They studied the Hadza tribe in northern Tanzania and as hunter-gatherers, the Hadzas spend their days being much more active than the typical Westerner.

The researchers expected the Hadzas to be able to eat a lot more as a result, but they found that the hunter-gatherers consumed around the same numbers of calories as those who live a Western lifestyle and had a similar energy expenditure too.

It strongly suggested that exercising without eating less would not help you lose weight.

A further US study conducted last year by the City University of New York found that those who exercise moderately burn about 200 calories more every day than those who dont at all, but exercising more than that didnt mean your energy expenditurebecame even higher.

Energy expenditure through exercise seemed to plateau at around 2,600 calories a day, the Mail Online reports.

Individuals tend to adapt metabolically to increased physical activity, muting the expected increase in daily energy [expenditure], the researchers explained.

The study suggests that exercising moderately willmean you burn more calories, but its not a case of the more you workout, the more you burn. Energy expenditure may have a limit.

Its unclear as to why this may be the case though - some experts suggest it could be because after youve exercised, you move less for the rest of the day because your body is tired - perhaps you take the lift instead of the stairs or fidget less.

Whats more, many people overestimate how many calories theyve burned off in the gym and so overcompensate by eating too much.

Professor Thijssen believes the key to weightloss is simply consuming less and cutting your calories.

Its worth noting, however, that other studies have reached different conclusions and found that there ismore of a linear relationship between exercise and energy expenditure.

Getting moving is undoubtedly good for the body - youll build muscle, tone your body and get fitter by working out. Whats more, exercising also reduces internal fat around your organs.

And many studies have shown that exercise reduces the risk of chronic conditions like type 2 diabetes, reduces blood pressure and improves brain and heart health

So dont hang up your trainers just yet, but if youre trying to lose weight, it could be worth skipping pudding once in a while.
