![]() “There is some evidence that consuming more protein can help to boost your metabolic rate by something called the thermic effect of food,” says Michael Mosley, creator of. “Once you account for body weight, age and amount of muscle and fat there is about a 10 per cent variability in metabolic rate,” she says. For those despairing that their DNA has doomed them to slow calorie burn, we do have some say in the matter, says Susan B Roberts, professor of nutrition at Tufts University in Boston and founder of. Too much saturated fat from butter and meat increases the risk of heart disease, though saturated fat from other dairy sources like full-fat yogurt and cheese does not seem to carry as great a risk, according to the latest research.īut increasing your fat intake isn’t the only way to take charge of your metabolism. Increasing our saturated fat intake is controversial. But in the meantime should we up our fat intake to increase our sluggish metabolic rates? ![]() Studies in mice have shown that when they eat more saturated fat their metabolism speeds up, a finding that will now need to be repeated in humans. We now eat less meat and dairy, due to the advice to cut saturated fats, and more ultra-processed carbohydrates, such as frozen pizzas and ready meals. One explanation given by the scientists was the way that our diets have changed. We’re moving more than we were in the 1980s, probably due to the trend towards exercising in our leisure time.Įxperts say this fall in our energy expenditure when our bodies are at rest (also known as our metabolic rate) could be a contributing factor in the growing obesity epidemic. It has widely been assumed that our lazy modern lifestyles mean we move less, but the researchers found the opposite is true. The heavier you are the more calories you burn, but since lean muscle tissue burns more calories than fat, two people of exactly the same weight may have very different processing speeds.īut now new research from the University of Aberdeen and the Chinese Academy of Sciences in Beijing has shown that over the past 40 years, average metabolic rates have plummeted.Īccording to the researchers’ calculations women are burning 122 fewer calories and men are burning 220 fewer than they were in the 1980s, despite us moving more than we were then. Metabolic speed is mostly a matter of genetics, with age, weight and height being the main determinants. It is an internal process running 24/7, turning what we eat into energy and governing everything from our circulation to breathing and cell repair. Our metabolism or basal metabolic rate quantifies how many calories we need each day in order to survive. ![]() If there’s one dinner-table experience shared the world over, it’s enviously watching someone super-slim wolf down dessert with the explanation: “I have a really fast metabolism.” It is surely among the most infuriating sentences in the English language for those more prone to the reverse, whose body’s apparently sluggish attitude to burning calories means a lifetime of staring wistfully into bakery windows.
