AceShowbiz - Gwyneth Paltrow's Goop website has come under fire from health experts over an article advising readers to target their "leanest liveable weight."
A Goop article headlined "Busting Diet Myths", described as being "supported by science," cites U.S. psychologist Dr. Traci Mann as stating that rather than attempting crash diets we should try to keep our weight at its "leanest liveable."
However, Cambridge University scientist Dr. Giles Yeo has branded the tip confusing and irresponsible in its use of language as those suffering from eating disorders may diet dangerously to keep their weight as low as possible.
"This is a dangerous suggestion, as many people will take it to mean they should be as thin as possible," he tells Britain's Daily Mail newspaper. "It is irresponsible because the idea is so open to misinterpretation, especially for young girls susceptible to eating disorders. The problem with many of Goop's recommendations is that they are not based on science, but pseudoscience."
Dr. Mann has defended her advice stating that her phrase refers to the leanest weight you can reach without dieting or extreme exercise regimes.
"I am strongly and clearly opposed to strict dieting," she tells the Mail. "In fact, the article is specifically about not dieting, not trying to lose too much weight and not doing anything unhealthy or extreme. The phrase 'leanest liveable weight' refers to the leanest weight you can be without doing any strict dieting or unhealthy behaviour."
Her 2015 book, "Secrets of the Eating Lab", advises against dieting, instead touting strategies to regulate eating habits to maintain a healthy weight.
Goop has been criticised for its promotion of unverified health advice in the past, and last year paid a $145,000 (£113,000) fine in California due to unproven claims - including ones made for the infamous 'vaginal eggs' sold by site.
Paltrow later announced she had hired a regulatory team to ensure its products were safe and properly advertised.
