| Posted 19 July 2022 Dnanalysis continues to claim efficacy for the genetic testing and diet/weight-loss efficacy. On the website, they claim “DNA Diet® is a genetic test designed to guide the personalisation of diet and lifestyle recommendations in order to manage weight. It provides insight into which diet type (low carbohydrate, low fat, or Mediterranean diet) would be most suitable for you according to your unique genetic makeup.” Yet years after starting with these claims, the evidence to back up claims that a DNA test can assist with weight-loss or weigh management remains very thin. Read the original article at The Conversation Here is the most recent article rebutting these claims: But, as people got older, we also noticed differences in their weight that couldn’t be explained by genetics or social background. This meant that neither of those factors is a good predictor of any particular person’s body weight.

Between 2007 and 2021, 1,068 unique dietary-supplement products were added to the database. A recent study has found that the products likely to include APIs were for sexual enhancement and weight loss. The author noted: - Since 2016, the percentage of products containing more than one API has increased.
- Since 2016, the percentage of adulterated products for sexual enhancement was higher, the percentage of weight-loss products was lower, and no muscle-building products were reported.
- Some products with APIs were removed from the market by the FDA because the risks were too great, some were never reviewed by the FDA, and some combined multiple APIs in ways that make it impossible to determine how benefits compare to harms.

Many clinical trials were also hampered by a significant risk of bias due to inconsistent testing methods. Problems with studies include small sample sizes, short follow-up periods, and poor study designs.

It will no longer allow ads containing testimonials about losing weight, references to body mass indexes, or those that “idealise or denigrate” certain body types. The company is the first major tech platform to prohibit weight loss ads. Apparently the US National Eating Disorders Association (NEDA) advised Pinterest on the policy change. “NEDA is encouraged by this necessary step in prioritising the mental health and wellbeing of Pinners, especially those affected by diet culture, body shaming and eating disorders,” said Elizabeth Thompson, interim CEO for the association, in the release. “We are hopeful this global policy will encourage other organisations and companies to reflect on potentially harmful … Read the rest 10 May 2021 Visitors of CamCheck will be aware of my claim that Herbex is a useless product for weight-loss and my evidence for making this claim. I have shown how Herbex uses ingredients that has not been shown to be effective for weight-loss, using them at miniscule dosages in their products. Recently Herbex has released Herbex UltraSlim, a product that has higher dosages but still no proof that the product works. This systematic review, presented at a recent obesity congress, concludes that “Herbal and diet supplements ‘have no effect on weight loss'”. Herbex claims that their mix of herbs does.

Do the big promises match the results, or do they only match the price tag? A search of the medical research database pubmed found there are no studies specifically on the use of “slimming teas” for weight loss, but there are studies on green and black tea. One review of five research trials compared changes in body weight in more than 300 adults at high risk of type 2 diabetes and heart disease. They gave people either green tea, a fermented tea called Puehr or tea extracts and compared the weight change to people who were given either placebo (non-active) tea extracts or no tea at all.

One in three slimmers have tried slimming pills purchased online, according to the joint #FakeMeds survey of 1,805 slimmers by the Medicines and Healthcare products Regulatory Agency and Slimming World.

One in three participants had taken substances bought through websites, according to the poll of 1,805 people released by the Medicines and Healthcare products Regulatory Agency (MHRA) and Slimming World. The UK government medicines regulator said many of the websites are unregulated and the diet pills are often fake and contain ingredients that have been banned because of their harmful side-effects. “Slimming tablets can seem like a quick-fix solution to weight problems, but some of them contain very dangerous ingredients,” said the senior MHRA policy manager Lynda Scammell. “It’s essential you know what you’re buying online and what the risks are.
