Fad diets, which promise instant and healthy results but actually end up making people indulge in over eating and miserably fail in the end, are making Britain's obesity crisis worse, a point which will be detailed by Professor Chris Hawkey, President of The British Society of Gastroenterology, in a key speech today.

Doctors have been criticizing fad diet for many years now, blaming the extreme nature of these routines which people find difficult to adhere to, and then end up eating even more unhealthy foods. Some of these diets cause people to eat too much of a certain food type, which actually makes them gain weight.

Professor Hawkey is of the opinion that, if Britons continue to follow unhealthy diets and eat certain foods more than others, every 9 in 10 adults will be overweight or obese by 2050. "The problem facing our society is not the content of our diet but it’s the quantity we are consuming and the consequential impact on obesity. We need to do away with quirky diets and get people to realize what will keep them healthy in the long run", the Professor will share.

Professor Hawkey will be sharing his thoughts on diets including rawsim, the grapefruit routine and the alkaline diet at the Gastro 2009 Conference, being held in London till Wednesday. He does, however, seems to have mixed feeling about the Atkins diet, but still stresses that it is not healthy and makes people eat lots of fats.
