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. There aren't any diets out there that people enjoy. But people do enjoy being physically active. But it is still much harder to exercise when you're already overweight, and "high energy density" foods are quick to get us there — overeating by just calories a day can lead to a weight increase of 10lb over a year. Does the coalition government — which will launch a White Paper on the subject this autumn — agree?
Anne Milton, minister for public health, is not keen to commit to any particular strategy before its publication. Change4Life [the government's current healthy-living initiative] is doing a good job. But we think there's still lots more we can do with it. Any drastic measures to curb the excesses of junk food marketing seem unlikely — both Milton and Secretary of State for Health Andrew Lansley stress the importance of working "with" industry — and much of her language is concerned with "individual choice". When it comes to losing weight, it seems there's only one real choice — stop eating so much food.
The good news The latest scientific findings from the US suggest that an intense workout in the gym is actually less effective than gentle exercise in terms of weight loss. Barry Braun, associate professor of kinesiology at the University of Massachusetts, says that the evidence emerging from his research team shows that moderate exercise such as "low-intensity ambulation" ie walking may help to burn calories "without triggering a caloric compensation effect" — ie without making you reach for a snack the moment you're done.
In one experiment, Braun showed that simply standing up instead of sitting used up hundreds more calories a day without increasing appetite hormones in your blood. The bad news Perhaps offering one reason for a multi-billion-pound weight-loss industry aimed almost exclusively at women, research has confirmed that it is more difficult for women to shed the pounds than men, because women's bodies are simply more efficient at storing fat. In one of Braun's experiments, in which overweight men and women were monitored while walking on treadmills, the women's blood levels of insulin decreased while appetite hormones increased; the men's, meanwhile, displayed no such change.

The cooking process should retain maximum nutrients and antioxidants in all our food, to sustain us and keep us looking and feeling younger.
Steam frying is my top way to cook rejuvenating, tasty meals, because it brings the richness of frying with less than 1 teaspoon of oil that tiny amount helps us to absorb the essential fat-soluble vitamins A, D, E and K. Eat ripe and red as they then contain more lycopene, an antioxidant that protects against cell deterioration and keeps you looking and feeling younger.
Eat four times a week for younger-looking skin, hair and nails. Eat in guacamole and salads or use for creamy smoothies, soups and puddings. An antioxidant and anti-inflammatory. Use raw for maximum pungency. Grate and mix with natural yogurt, cider vinegar or grated apple as a sauce for pulses or fish.
Nothing beats cucumber for dewy skin.
Underrated and underused in the West, radishes are fabulous detoxers; if ever you feel like an inner cleanse, eat a radish. They are low-cal, high-fiber and anti-inflammatory. Delicious raw in salads or steamed with other vegetables; they add a sharp antidote to any sweetness. Naturally high in sugars, parsnip is very high in soluble and insoluble fiber, which reduces blood cholesterol and helps gut function.
Juice raw with other vegetables it adds sweet creaminess , roast, use in soup. Kale is a nutritional powerhouse, probably the most palatable way to get a big shot of calcium in a low-cal way. High in protective carotenes and anti-inflammatory, these help regulate blood sugar and are youth-giving for skin and muscles.
Roast to make into soups, or add to casseroles, curries and risottos. Go for these over regular mushrooms: They offer a rejuvenating boost. They reduce cholesterol and help fight infection and disease. A good little youth-giving helper, full of vitamins C and E, potassium, magnesium and dietary fiber.
These buttery, nutty legumes are a great low-fat, high-protein option. They help to reduce cholesterol and blood sugar and are high in iron and molybdenum, a mineral that helps detox the sulphites in processed foods and wine. Use in hummus, falafel, pies, curries, casseroles, soups or salads. Powerfully nutrient-dense, high not just in vitamins and minerals but in cancer-fighting compounds and amino acids that help detox at a cellular level, this is the Holy Grail of anti-aging. Carrots contain high levels of beta carotene and other antioxidants, with protective powers against cancer, heart disease, high cholesterol and even sight problems.
Juice, eat raw or cooked in soups, breads and cakes. Buy organic, or always peel them, as the skin can harbor pesticide residues. Currants are super-rich in GLA gamma-linolenic acid , which is very good for skin.
Eat raw with coconut cream or add to ice cream. Try frozen when fresh is not available. This is highly alkalizing, and a good source of minerals and fats that fight bacteria and fungi. Good for lowering depression and boosting memory. This Peruvian grain is a great protein source for the gluten- and wheat-free. Cook on its own or chuck raw into soups and casseroles.
They are far from malnourished or starving.
Take Sherman, a year-old monkey from NIA. View image of Rhesus monkeys given a stricter, low calorie diet lived longer Credit: As younger monkeys were developing diseases and dying, he seemed to be immune to ageing. The same is true, to varying extents, for the rest of his experimental troop at NIA.
In , the University of Wisconsin trial published similarly spectacular results. Not only did their CR monkeys look remarkably younger — with more hair, less sag, and brown instead of grey — than monkeys that were fed a standard diet, they were healthier on the inside too, free from pathology.
The risk of heart disease was similarly halved. In an update study from the University of Wisconsin in , this percentage remained stable.
The results show that ageing itself is a reasonable target for clinical intervention and medical treatment — Rozalyn Anderson. If ageing can be delayed, in other words, all of the diseases associated with it will follow suit. Whereas if you go after ageing you can offset the lot in one go.
View image of Calorie restriction involves a permanent reduction in a diet Credit: Eating less certainly seemed to help the monkeys, but calorie restriction is much tougher for people out in the real world. For one, our access to regular, high-calorie meals is now easier than ever; with companies like Deliveroo and UberEats, there is no longer a need to walk to the restaurant anymore. And two, gaining weight simply comes more naturally to some people.
And then someone else walks past a table with a cake on it and they have to go up a pant size. Ideally, the amount and types of food we eat should be tailored to who we are — our genetic predisposition to gaining weight, how we metabolise sugars, how we store fat, and other physiological fluxes that are beyond the scope of scientific instruction at the moment, and perhaps forever. But a predisposition to obesity can be used as a guide to life choices rather than an inevitability. Not only has Roberts seen the problems of obesity first-hand in her family, she knows the benefits of CR better than most.
Over two years, healthy men and women aged between 21 and 50 years were split into two groups. Both had health checks every six months. But the Calerie trials tested for the next best thing: Published in , the results after two years were very positive. Significant health benefits may be garnered in an already healthy body, but further trials are needed. Admittedly, some benefits may come from weight-loss. Earlier trials from Calerie had included people that were obese as well as those with a healthy body mass index BMI of 25 or below, and slimming down would have certainly improved the welfare of the heavier participants.
Diseases and disorders previously thought to be age-associated diseases are now popping up in the obese population, she adds. That is, someone whose BMI lies between
