We'd all like a body like Heidi Klum but is a pill the answer?
A slim celebrity body like Kelly Brook's or Heidi Klum could be more achievable now as a weight loss pill which stops the body absorbing fat will now be sold over-the-counter, the BBC reports.
Orlistat will be available at a lower dose than usually prescribed by doctors but is aimed at adults with a Body Mass Index of 28 or more. A BMI between 18.5 and 24.9 is healthiest.
The pill is thought to help people with weight loss but only if they make a conscious decision to eat less fatty foods. GlaxoSmithKline, who make the pill said that trials found that adding Orlistat to a low fat diet with a reduced calorie intake can help people loose 50% more weight than just dieting. If users do however continue to eat fatty foods they will suffer side effects including diarrhoea and gas problems.
Dr Ian Campbell, medical director of the charity Weight Concern, said: "It can work, the risks are minimal, but I don't want to see the public being exploited. They have got to use it with knowledge.
"This plays a part in the a weight management regime - but lifestyle changes in terms of eating a better diet must come first and last."
But Professor Alan Maryon-Davis, president of the Faculty of Public Health, has concerns over the pill though. She said: "My worry is that a lot of people will take these pills without proper advice and support about dieting and exercise."
"It's all too easy to pop a pill instead of making the lifestyle changes we need to keep our weight under control.
