To burn off an extra calories is typically an extra two hours of cycling. And that's about two doughnuts. From a practical perspective, then, exercise is never going to be an effective way of slimming, unless you have the training schedule — and the willpower — of an Olympic athlete. But Gately sums it up: "Most people, offered the choice, are going to go for the diet, because it's easier to achieve. There's another, more insidious, problem with pinning all your hopes for a holiday bod on exercise. In what has become a defining experiment at the University of Louisiana, led by Dr Timothy Church, hundreds of overweight women were put on exercise regimes for a six-month period.
Some worked out for 72 minutes each week, some for minutes, and some for A fourth group kept to their normal daily routine with no additional exercise.
Against all the laws of natural justice, at the end of the study , there was no significant difference in weight loss between those who had exercised — some of them for several days a week — and those who hadn't. Church doesn't record whether he told the women who he'd had training for three and half hours a week, or whether he was wearing protective clothing when he did. Some of the women even gained weight. Church identified the problem and called it "compensation": those who exercised cancelled out the calories they had burned by eating more, generally as a form of self-reward.
The post-workout pastry to celebrate a job well done — or even a few pieces of fruit to satisfy their stimulated appetites — undid their good work. In some cases, they were less physically active in their daily life as well. His findings are backed up by a paper on childhood obesity published in by Boston academics Steven Gortmaker and Kendrin Sonneville. In an month study investigating what they call "the energy gap" — the daily imbalance between energy intake and expenditure — the pair showed that when the children in their experiment exercised, they ended up eating more than the calories they had just burned, sometimes 10 or 20 times as many.
In the s, the celebrated French-American nutritionist Jean Mayer was the first to introduce a link between exercise and weight reduction. Until then, the notion that physical activity might help you lose weight was actually rather unfashionable in the scientific community — in the s, a leading specialist had persuasively argued that it was more effective to keep patients on bed rest.
Over the course of his career, Mayer's pioneering studies — on rats, babies and schoolgirls — demonstrated that the less active someone was, the more likely they were to be fat. Mayer himself, the son of two eminent physiologists, and a Second World War hero to boot, became one of the world's leading figures in nutrition and most influential voices in the sphere of public health.
As an advisor to the White House and to the World Health Organisation, he drew correlations between exercise and fitness that triggered a revolution in thinking on the subject in the 60s and 70s. Each successive postwar generation was enjoying an increasingly sedentary lifestyle, and those lifestyles have been accompanied by an apparently inexorable increase in obesity.

Three in five UK adults are now officially overweight. And type II diabetes, which used to be a disease that affected you at the end of your life, is now the fastest-rising chronic disorder in paediatric clinics. But have we confused cause and effect? Terry Wilkin, professor of endocrinology and metabolism at the Peninsula Medical School in Plymouth, argues that we have.
The title of his latest research is: "Fatness leads to inactivity, but inactivity does not lead to fatness". Wilkin is nearing the end of an year study on obesity in children, which has been monitoring the health, weight and activity levels of subjects since the age of five.

When his team compared the more naturally active children with the less active ones, they were surprised to discover absolutely no difference in their body fat or body mass. That's not to say that exercise is not making the children healthy in other ways, says Wilkin, just that it's having no palpable effect on their overall size and shape. For one thing, Wilkin believes he has discovered another form of "compensation", similar to Timothy Church's discovery that we reward ourselves with food when we exercise.
Looking at the question of whether it was possible to change a child's physical activity, Wilkin's team put accelerometers on children at schools with very different PE schedules: one which offered 1. But when they got home they did the reverse. Those who had had the activity during the day flopped and those who hadn't perked up, and if you added the in-school and out-of-school together you got the same.

From which we concluded that physical activity is controlled by the brain, not by the environment — if you're given a big opportunity to exercise at one time of day you'll compensate at another. Wilkin argues that the environmental factors we tend to obsess about in the fight against obesity — playing fields, PE time in school, extracurricular activities, parental encouragement — are actually less of a factor in determining what exercise we do than our own bodies.
In other words, what physical activity you do is not going to be left to the city council to decide. It's going to be controlled, fundamentally, from within. His thesis has caused controversy among his peers — there have been cavils that his study sample is inconclusively small — and not all obesity experts appreciate the message.
Those who are saying it has no impact are neglecting a huge amount of the literature. I am suspicious of anyone who polarises obesity as one thing over another when there is strong agreement that it has multiple causes. In people who have lost weight and kept weight off, physical activity is almost always involved. And those people who just do diet are more likely to fail, as are those who just do exercise. You need a combination of the two, because we're talking about human beings, not machines. We know that dietary behaviour is quite a negative behaviour — we're having to deny ourselves something.
Use that jog to catch your breath, then hit the next sprint hard. Perform these intervals for 15 minutes, then end with a 5-minute jog. When you start feeling stronger in your runs, try upping the sprint effort to 20 seconds with 40 seconds of jogging. Jumping rope is a full-body workout. Fire up your quads and glutes to help you explode from the ground, and engage your core to keep you upright and stable as you land back down.

If you don't like running, spinning is a low-impact alternative that'll crank up your heart rate. But there's more to pushing the pedal than speed.
