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.

As we grow, however, the brown fat content of our bodies decreases. In the neck Sweaty bodies
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

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
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.
The Iceman Grubeth Welcome to the UFC Fit weekly series of articles on proper nutrition & fitness from the biggest names in mixed martial arts...this week, UFC Hall of Famer Chuck Liddell UFC Hall of Famer Chuck Liddell There was a time early in his MMA career, Chuck Liddell admitted, when Mountain Dew and Fruity Pebbles were his idea of The Diet of Champions. But, rest assured, Liddell wasn’t consuming cartoon character cereal and soda pop when he won and defended the UFC light heavyweight title. In this interview, the UFC icon discusses his past and present diet, how he’s been keeping busy since bidding adieu to the Octagon, and his pursuit of a Brazilian jiu-jitsu black belt. WHAT ARE YOU EATING THESE DAYS CHAMP? I don’t drink soda very often. I eat a lot of organic stuff – my wife buys a lot of organic stuff. I was averaging probably about 4,500/5,000 calories a day, so I had to eat a lot of calories. When I first started my MMA career I worked with some guys for strength and conditioning. Yeah.
Understanding Neocarnism: How Vegan Advocates Can Appreciate and Respond to “Happy Meat,” Locavorism, and “Paleo Dieting” These days, few commentaries cause vegans more despair than those proclaiming the virtues of eating “humane” meat, those promoting the ethics of eating “sustainable” meat, or those insisting on the nutritional necessity of eating any meat. Exasperated vegans wonder why, despite years of seemingly successful campaigning to raise awareness about the impact of animal agriculture on animals, the environment, and human health, these same concerns would actually be used to defend meat eating. Yet it is not despite vegan advocacy, but largely because of it that such defensiveness has made its way into public discourse. The new wave of pro-meat arguments is in part an attempt to defend the weakened meat-eating establishment against the very real threat posed by an increasingly powerful vegan movement. Carnistic Backlash A backlash is a defensive, often unconscious response by dominant interests to threats against their power. Neocarnism Compassionate Carnism: Eating Animals is Normal
When you eat beats what you eat in staying healthy - health - 18 May 2012 Preventing obesity may be down to timing, in mice, at least. Mice allowed meals only within an 8-hour period were healthier than those that munched freely through the day, even when they consumed more fat. A link between obesity and the time you eat meals makes sense, says Satchidananda Panda of the Salk Institute in La Jolla, California, as food choices generally get less healthy as the day progresses. Breakfast may include healthy fruits and grains, but late-night snacks are more likely to involve high-fat ice cream or high-calorie alcohol. Furthermore, research has shown that our internal clocks are closely tied to our metabolism; disrupting them can cause weight gain and diabetes. Panda and colleagues fed two groups of mice a high-fat diet. Three months later, the weight of mice on the all-day, high-fat diet had increased by 28 per cent. Panda reckons the shortened feeding period gives metabolic systems longer to perform their function uninterrupted by a new influx of nutrients.
