Lifewatch: Unhealthy Diets

WILMINGTON -- A new study suggests the obsession to become thin could be forcing women into a "famine then feast" type of behavior.

Published research explains a condition described as "binge priming," a condition where people become addicted to fatty foods once their diet has finished.

According to experts, constant images of very thin models encourage an unhealthy desire in other people to imitate them.

But now, research shows the battle for size zero is not only putting our weight at risk, but also our brain.

New research published in the British Journal of Psychiatry states that studies on animals show that starvation followed by binging on fatty foods such as burgers or chocolate can lead to a desire to over consume and engage in addictive behavior.

"If you starve yourself, you might overeat. You can't keep a starved state going. It is dangerous because it affects the way our brain works and the whole of the rest of our body. And it can lead us to overeat and become unhealthily and obsessive with our food. So binge priming is quite a dangerous way of acting," said Susan Ringwood the CEO of Beating Eating Disorders.

The size zero debate reared its head at London's Fashion Week as protestors rallied against the use of skinny models.

Some model agencies reject women for being too thin, including Emma-Jane Dolphin.  At size 14, she believes keeping healthy should be a model's priority.

"It's primal that you eat when you're hungry and if you're being deprived of that, then you're not going to be relaxed and your nervous system is going to be working overtime. It's just going to lead to all sorts of problems and illnesses later on. So I think eat regularly like everyone else," said Dolphin.

Most people wouldn't mind to lose a few pounds, but hopefully these new discoveries about the threat of "famine and feast" eating will encourage a little moderation.

We're not all designed to be size zero, and health experts are hoping more people will realize that.
