Elle Macpherson, Baroness Mone criticized for having 'the worst celebrity diet'; see the details here

Different bodies need different diets. That's the main reason why a diet may not work for everybody because genetically and metabolically, people are not created the same. It's also now common for celebrities to sign on and endorse several diets, slimming pills, and other weight loss products, attaching their name to something they believe works for them. However, some endorsements do not go as planned.

In fact, The Telegraph reports that British entrepreneur and parliamentarian Michelle Mone or Baroness Mone and Australian model and actress Elle Macpherson are being criticized by the British Dietetic Association (BDA) for supporting questionable weight loss methods.

Baroness Mone is also the founder of lingerie brand Ultimo and stakeholder of TrimSecrets, a five-step slimming plan involving diet capsules that according to their official website, is a "fully HMFA and FDA certified and approved product."

TrimSecret advises consumers to follow a strict 1,500 calorie per day diet on top of the 14-day capsule intake. Mone claimed that the tablets helped her lose as much as two pounds per week.

However, BDA consultant dietitian and a council member Sian Porter claims that there is no proof behind the weight loss powers of the tablets. He said, "By consuming 1500 calories a day, most individuals should lose weight regardless of whether they are taking this pill. TrimSecrets is giving the impression that there's a pill or potion that's the key to weight loss."

"There have been deaths this year from diet pills—not this specific one," he warned. "But it's really about people learning to manage their lifestyles without expensive gimmicks. As with all these things, if they were tried and tested, they would be used by the Department of Health."

Deadline News U.K. reports that according to BDA spokesperson, "Any person in a position of authority should not be advertising this. It’s sending a big message to the whole of the U.K., particularly young girls, that they are promoting this cycle of weight loss."

Elle Macpherson, who also credits The Super Elixir for her fit body at 51 years of age, was also questioned by the BDA. The Super Elixir, according to their website, is a "highly specialised alkalising greens supplement with vitamins, minerals and trace elements to assist wellness".

According to Porter, "The benefits that this costly powder claims to provide can easily be obtained from fruit and vegetables, and a balanced diet."

Speaking of a balanced diet, the Mirror reports that according to the BDA, "People get drawn in by so-called ‘super foods’ but no one food can provide all the nutrients you need. It’s all about balance."

Before embarking on any weight loss endeavors, it is best to consult one's doctor for the best diet and exercise plans depending on one's current and target weight. Always consult a doctor before consuming any diet and weight loss pills or powders.
