Intensive crash diets are likely to last just 15 days and could end up gaining more weight, shows study.
Findings have revealed that average 'crash' diet lasts just 15 days and 35 per cent say they end up putting on more weight than they lost in the first place, with an average 4.7 pounds creeping back on post-diet.
A poll of 2,000 women conducted by Hovis Wholemeal bread suggested that a balanced diet is a more effective way of losing weight in the long-term, the Daily Mail reported.
"It's worrying to think that women put pressure on themselves to lose weight quickly and then suffer emotional repercussions if they give up or don't see the desired results," Olympic cyclist Victoria Pendleton said while commenting on the study.
"The secret to a healthy lifestyle is not crash diets."
She asserted that increasing the amount of exercise will allow dieters to eat more of what they want without packing on any extra weight.
Most of the Brits notice the pounds piling on 22 days after their diets end and only one in five women successfully achieve their target weight.
According to experts, Dukan Diet, which works on restricting foods, calories and portion control, is the worst celebrity weight loss plan to follow and said it has 'absolutely no solid science behind it at all'.
