DNA Diet – Dnalysis still ‘duping’ clients?

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.

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.

Study looks at tainted dietary supplements

Posted 06 July 2022

The U.S. Food and Drug Administration’s Tainted Supplements Database, created in 2007, lists products adulterated with active pharmaceutical ingredients (APIs). 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.

Dangerous weight loss products for sale online with no health warnings

Which? finds substances that can cause heart problems being sold on eBay, Wish and AliExpress

Denis Campbell Health policy editor, The Guardian

Wed 25 Aug 2021

“Dangerous” weight loss products containing substances that can induce a stroke or heart attack are being sold on websites such as eBay without any health warnings, an investigation has found.

The consumer group Which? found dozens of products on sale online containing plant extracts that can make users agitated or aggressive and increase their heart rate and blood pressure.

They all contained either yohimbine or synephrine, substances that the Medicines and Healthcare products Regulatory Agency (MHRA) has said have “considerable potential to cause harm if used without medical supervision or advice”.

Which? bought nine such products, which are used by some people seeking to lose weight, bodybuilders and gym-goers, through the online marketplaces eBay, Wish and AliExpress. Of those, two … Read the rest

Evidence lacking for “alternative” weight-loss therapies

Posted 07 July 2021

A systematic review of published research evaluating the efficacy of dietary supplements and “alternative therapies” for weight loss among people at least 18 years of age has found that supportive evidence is weak. 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.

Key findings included:

  • Out of 315 randomized controlled trials included in the review, 52 were classified as having a low risk of bias, of which 16 demonstrated significant weight changes for tested therapies compared to placebo.
  • No high-quality evidence supported acupuncture, calcium-vitamin D supplementation, chocolate/cocoa, phenylpropanolamineguar gumPhaseolus vulgarispyruvate, and mind-body interventions as weight-loss

Evidence for claims in weight-loss ads is slimmer than you’ll be

Posted 05 July 2021

Was Pinterest right to ban advertising for diet products on its platform?

Wendy Knowler TimesLive 04 July 2021

Pinterest has banned all weight loss ads on its platform, as part of its policy not to support body shaming advertising.

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

Herbal and diet supplements ‘have no effect on weight loss’

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. I would rather believe evidence, of which they have zero.

Science or Snake Oil: do skinny teas boost weight loss?

Posted 18 December 2017

From The Conversation:

Weight loss teas are becoming common, with advertisements claiming dramatic results often appearing online. 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.

New research shows desperate dieters in danger – the secret world of online slimming pills

Posted 14 December 2017

Published: 30 November 2017

The Medicines and Healthcare products Regulatory Agency (MHRA) is working in partnership with Slimming World as part of the Agency’s wider #FakeMeds Campaign to encourage those wanting to lose weight to turn to safe, legitimate and appropriate routes.

Online sellers of potentially dangerous slimming pills containing withdrawn pharmaceutical ingredients are putting desperate dieters’ health at serious risk by seducing them with the promise of quick-fix weight loss and discreet deliveries that bypass discussions with their GP and pharmacist, new research reveals.

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. Since April 2013, the Agency has seized nearly £4 million worth of dodgy weight loss pills.

One-third of UK dieters have used slimming pills bought online – report

Posted 30 November 2017

UK medicines regulator warns that many of the websites are unregulated and sell fake diet pills containing banned ingredients

One-third of people trying to lose weight have tried potentially dangerous slimming pills bought online, a government survey has found.

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. If you don’t, your weight could Read the rest
