The world's largest study of weight loss has shown that diets do not work for the vast majority of slimmers and may even put lives at risk.

More than two-thirds pile the pounds straight back on, raising the danger of heart attack, stroke and diabetes.

Indeed most dieters end up heavier than they did to start with, the researchers found.

They warn this type of yo-yo behaviour is linked to a host of health problems. And they say the strain that repeated weight loss and gain places on the body means most people would have been better off not dieting at all.

The findings follow other research that shows the UK is in the grip of a dieting frenzy, with one in four Britons at any one time trying to lose weight.

The average woman is estimated to lose and gain 251/2 stone during her lifetime - putting on 151/2 stone for the ten stone she loses through dieting. Last night, the U.S. scientists behind the latest research - the most thorough and comprehensive analysis of its kind - said that dieting simply does not work.

The University of California researchers analysed the results of more than 30 studies involving thousands of slimmers.

Although the overview did not name specific weight loss plans, popular diets in recent years include the low carbohydrate, high protein Atkins diet and the GI diet, which is rich in slow-burning wholegrain carbohydrates.

Pooling the results of the various studies clearly showed that while people do lose weight initially, most quickly put all the pounds back on.

In fact, most people end up weighing more than they did to begin with. Researcher Dr Traci Mann said: "You can initially lost 5 to 10 per cent of your weight on any number of diets.

"But after this honeymoon period, the weight comes back. We found that the majority of people regained all the weight, plus more. Sustained weight loss was found only in a small minority of participants, while complete weight regain was found in the majority."

Dr Mann's research showed that up to two-thirds of dieters put on all the weight they lose - and more - over a four to five-year period. Half of those taking part in one study were more than 11lb heavier five years later, while dieters taking part in another study actually ended up heavier than other volunteers who hadn't tried to lose weight.

A four-year study into the health of 19,000 men revealed that most of those who put on weight had dieted in the years before the start of the study.

Bleak as these figures seem, the true picture could be even worse, as it is thought that most people lie about their weight - and don't like to tell researchers that their weight has started to creep up again.

The analysis, published in the journal American Psychologist, concluded dieters may actually be damaging their health.

Research has shown the repeated rapid weight gain and loss associated with dieting can double the risk of death from heart disease, including heart attacks, and the risk of premature death in general.

Such yo-yo weight loss has also been linked to stroke and diabetes and shown to suppress the immune system, making the body more vulnerable to infection.

Dr Mann said: "We decided to dig up and analyse every study that followed people on diets for two to five years. We concluded most of them would have been better off not going on the diet at all.

"Their weight would have been pretty much the same, and their bodies would not suffer the wear and tear from losing weight and gaining it all back.

"The benefits of dieting are simply too small and the potential harms of dieting are too large for it to be recommended as a safe and effective treatment for obesity."

The psychologist, who advises would-be slimmers to swap calorie-controlled diets for a balanced diet coupled with regular exercise, added: "Exercise may well be the key factor leading to sustained weight loss.

Studies consistently find that people who report the most exercise also have the most weight loss."

The finding comes as Britain fights a rising tide of obesity.

A growing reliance on fast food and time-saving technology has led to the UK developing the worst weight problem in Europe, with almost a quarter of adults classed as obese.

Last night, British experts said that fad diets do not work and that the key to maintaining a healthy weight is making gradual, long-term changes.

Dr Beckie Lang, of the Association for the Study of Obesity, said: "Maintaining a healthy weight isn't about going on a diet and coming off a diet when you reach your target weight. It is about adopting skills that change your eating habits for life."

If people would just eat properly 90% of the time and get a little excersize, it wouldn't be an issue. I look at excersize and fitness like brushing your teeth or any other part of your daily hygene routine. Excersize should be like that. Just a daily part of your routine.

Furthermore, eating most of the time, should be seen as a business or a necessary action. When EVERY meal you consume is treated like a form of recreation, you will NEVER eat right.

I found that the first trick to losing weight is simply eating less. Now, I don't mean starving yourself, as this is one of the reasons diets fail (they starve you). But just simply start cutting back on how much you eat. The key is to stop eating when you feel satisfied. If you feel full, you ate too much.

One you learn to eat to satisfaction, and then only eat when you actually feel hungry, you will be amazed at how your clothes will suddenly become looser and looser.

Once you have learned to control your volume, then you can work on cutting back the butter and french fries and desserts and what not.

I eat whatever I want...in moderation...I excercise 30 mins a day 6 days a week...and I absolutely put no food in my mouth after 6:00pm...if I have to "munch" something after that time...its always carrots/celery...a crunchy veggie :thumbsup:

For me, just not eating after 6 made a huge difference.

Love and Blessings,

Angel

A little bit goes a long way. I just started a diet yesterday. No sugar and no starch for two weeks. And exercise at least 20 minutes. I can't lose weight just with diet, I must have exercise. I find that what I eat pretty much has no effect if I exercise correctly.

I went on one diet in my life...lost 30+ pounds...and felt like I was constantly eating the entire time. I learned its not the quantity of the food, but the quality. Now, several years later, I am almost back to my pre-diet weight...but alot of that is from working out and gaining muscle. I think that people who are motivated and focused are fine to diet...however, if you've been on 3 diets and are looking to a 4th...then this article is for you.

Same for me. Lately since I got married, I have been eating....a wee bit too much, so I added an extra day to my regular workout routine and have taken up jogging again. And can I just say how great it is jogging in the desert where it's 80 degrees and I don't sweat?? Simply amazing.

I also try never to eat after 6 pm.

But that Jewish and Italian food, (Marnie's specialty) which is so good, is so darn fattening! Pass the manna, please!

When a person eats 2 plate-fulls of of food for a meal? Work on the quantity first. That's what I mean. ;)
