Why brown fat is 'good' in the fight against obesity 28 July 2012Last updated at 20:27 ET By Philippa Roxby Health reporter, BBC News White fat is the 'bad' stuff which stores energy rather than burning off calories What produces 300 times more heat than any other organ in the body? Scientists have discovered that this type of fat is a good thing because it produces lots of heat by burning calories. Unlike white fat, which clings to our hips and expands our ageing waistlines, brown fat keeps the weight off. And that's why the race is on to find out more about brown adipose tissue, also known as brown fat, and how humans could use it to our advantage.

Everything you think you know about healthy eating is wrong! By Maria Lally Published: 21:10 GMT, 24 June 2012 | Updated: 08:19 GMT, 25 June 2012 Low-fat salad dressing is better than mayonnaise, fat makes you fat and you can’t eat enough fruit, right? ‘When a new client comes to see me, they nearly always reel off the list of “good” things they’re doing diet-wise,’ says James Duigan, author of Clean & Lean, and personal trainer to the stars, including Elle Macpherson. ‘Each time, I shake my head and tell them these so-called “good” diet traits are sabotaging their efforts to slim.’ So if you’re trying to eat well, here’s everything you need to know (but probably didn’t)… You should add fat to your diet: Your body absorbs nutrients better when you eat a little fat with them Myth: Low-fat salad dressing is good for you Drizzling a fat-free dressing over your salad isn’t as healthy as it seems, or so says a study. Scientists found that eating your salad alongside a little fat helps your body absorb the nutrients from the vegetables more efficiently.
Calorie restriction Two trials have been performed involving primates, but have not demonstrated increases in median lifespan. A study of rhesus monkeys begun in 1987 by the National Institute on Aging published results in August 2012 that found evidence of health benefits, but did not demonstrate increased median lifespan.[2] A study by the University of Wisconsin beginning in 1989 is still ongoing.[1][3][4] Research on maximum life span in that study is still ongoing. Research history[edit] In 1934, Mary Crowell and Clive McCay of Cornell University observed that laboratory rats fed a severely reduced calorie diet while maintaining micronutrient levels resulted in life spans of up to twice as long as otherwise expected. These findings were explored in detail by a series of experiments with mice conducted by Roy Walford and his student Richard Weindruch. The findings have since been accepted and generalized to a range of other animals. Effects on humans[edit] Positive effects[edit] Negative effects[edit]
Dieticians say extra protein can do more harm than good By Rick Kelsey Newsbeat reporter There is a warning that gym supplements are often doing more harm than good to people using them. The British Dietetic Association (BDA) says high levels of additional protein can cause side-effects, which can include nausea as well as kidney and liver damage. It wants clearer warnings about what is in the powders and tablets. Manufacturers say consumers are well protected with only 11 reported reactions in 11 years. Jane Griffin is a former British Olympic dietician and speaks for the BDA. "The more protein in your diet the more you have to get rid of," she said. "People who have these high protein diets are now running into problems with their kidneys because of the amount of protein they must get rid of." The body needs protein for muscle growth and many gym-goers use it to try to get bigger quickly. Gym supplements come under food law, so although they have to be labelled properly what is in them can vary. DMAA warnings Continue reading the main story
Diet tips: Cut out 300 calories for good or you'll pile the pounds straight back on Experts now know why so many dieters pile the pounds straight back onSlimmers need to eat less than someone of the same weight who has not dietedThe phenomenon is caused by the effect dieting has on the way muscles work By Fiona Macrae Published: 22:29 GMT, 15 May 2012 | Updated: 11:40 GMT, 16 May 2012 As every slimmer knows, it is when the diet ends that the hard work really begins. Despite the best of intentions, only a few lucky ones manage to avoid piling the pounds straight back on. Now experts think they know why – and it’s nothing to do with a lack of willpower. Hard work: When a diet comes to an end a long-term cut in calories is needed to keep the weight off, new research suggests To stay at their new weight, it seems, slimmers needs to eat less than someone of the same weight who has not dieted. To be precise, they need to eat at least 300 fewer calories a day. And over the course of a week, it amounts to 15 cans of cola or 17 slices of buttered toast.

What caused the obesity crisis in the West? 13 June 2012Last updated at 07:25 ET British people are on average nearly three stone (19kg) heavier than 50 years ago, but who or what is to blame? Jacques Peretti (pictured above) investigates. Contrary to popular belief, we as a race have not become greedier or less active in recent years. "Genetically, human beings haven't changed, but our environment, our access to cheap food has," says Professor Jimmy Bell, obesity specialist at Imperial College, London. "We're being bombarded every day by the food industry to consume more and more food. "It's a war between our bodies and the demands our body makes, and the accessibility that modern society gives us with food. One of the biggest changes in our modern diet stems back to the 1970s when US agriculture embarked on the mass-production of corn and of high-fructose corn syrup, commonly used as a sweetener in processed foods. According to nutritionist Marion Nestle, this paved the way for obesity. Weight gain Continue reading the main story
Yes, you CAN think yourself thinner... By Louise Atkinson Updated: 00:19 GMT, 1 March 2012 Every year we spend millions on diets and gym membership, but obesity specialists increasingly believe the problem doesn’t lie in what we eat or how much exercise we take, but how we think. ‘There is a non-stop communication between your mind and body, but the mind is the most important because it drives your behaviour,’ says nutrition and exercise specialist Janet Thomson, author of Think More, Eat Less. She is convinced we become overweight as a result of confused messages from the brain sabotaging our attempts to slim. Exercise specialist Janet Thomson is convinced we become overweight as a result of confused messages from the brain sabotaging our attempts to slim So, if we have been told we are ‘well-built’ or ‘chubby’ or that ‘dieting is a waste of time’, the messages can stick. THINK about how you will look and feel a month after you have achieved your weight- loss goal — slim and healthy.
Aging healthfully is not just a matter of having good genes But not necessarily a lot of effort. Aging well — or, at least, aging better — doesn’t have to be that hard. After talking to many aging experts and looking at the latest findings on aging from around the world, it’s clear that people can improve the way they will age. To start with, you need to know what makes you age, and that means you have to pay attention to what happens inside your cells, where aging begins. Scientists are finding that most of the cellular processes that cause the body to gradually decline with age are affected by diet, lifestyle, exercise, stress and other outside influences. For example, the food you eat influences the production of harmful free radicals during metabolism. Scientists have also discovered the role of telomeres in aging (See “Field of Inquiry” on Page E4.) So, your lifestyle can affect the microscopic processes going on in your cells day in and day out. But you have to keep it up. Bake, don’t broil Skip a meal Of course, living this way is not fun.
