FDA warns consumers to avoid HCG weight-loss products

Continue Reading 0

Posted 30 July 2020

The Food and Drug Administration (FDA) is advising consumers to avoid human chorionic gonadotropin (HCG) weight-loss products. These products are typically sold in the form of oral drops, pellets and sprays, and can be found online, at weight loss clinics and in some retail stores. Claims that HCG can “reset your metabolism” and change abnormal eating patterns are unsubstantiated. HCG is a hormone produced by the placenta during pregnancy. The FDA has approved HCG as a prescription drug for the treatment of female infertility and for other medical conditions, but not for weight loss and not for use without a prescription for any purpose. Marketing of HCG for weight loss is typically accompanied by the recommendation to limit calorie intake to 500 per day, which is dangerous.

Avoid dangerous HCG products. FDA consumer update, July 13, 2020

Ketovatru – Major scam – beware!

Posted 29 June 2020

Ketovatru is promoted as a weight-loss product. The company claims that Prof Tim Noakes and Dr Moll endorse this product.

The scam even appears to show Prof Noakes responding to comments – but these are lies – they are not his comments.

Neither Dr Moll nor Prof Noakes have endorsed this product, and the scam artists are using their names and photos without permission. Furthermore, there are many comments on Facebook pointing out that money was taken and no product delivered.

Beware, avoid.

Science Has Shown These Five Weight Loss Supplements Are a Waste of Money

The Conversation 8 Dec 2019

When you google “weight loss” the challenge to sort fact from fiction begins.

These five supplements claim to speed up weight loss, but let’s see what the evidence says.

1. Raspberry ketones

Raspberry ketones, sold as weight loss tablets, are chemicals found in red raspberries responsible for that distinct raspberry flavour and smell. You can also make raspberry ketones in a lab.

A study in obese rats found raspberry ketones reduced their total body fat content.

In one study, 70 adults with obesity were put on a weight loss diet and exercise program, and randomised to take a supplement containing either raspberry ketones, or other supplements such as caffeine or garlic, or a placebo.

Only 45 participants completed the study. The 27 who took a supplement lost about 1.9 kilos, compared Read the rest

‘Appetite suppressant’ lollipops and ‘detox’ teas have been promoted by the company’s hand-selected celebrities and Instagram models.

The product for sale – 35 calories worth of flavored cane sugar laced with an extract of saffron that supposedly curbs hunger – sparked immediate backlash for a company that had built its brand selling so-called “detox” teas. Good Place actor Jameela Jamil called out Kim Kardashian West for promoting the lollipops to her 116 million Instagram followers (“You terrible and toxic influence on young girls,” Jamil tweeted), and more than 100,000 people signed an online petition calling for the billboard’s removal.

“Dietary supplements sold for detox or weight loss are snake oil, plain and simple,” said Dr S Bryn Austin, a Harvard Medical School professor who specializes in eating disorder risks. “The liver and kidneys already do the the so-called detox and adding junk products into Read the rest

Alkaline diet: Separating pHacts from pHiction

Continue Reading 0

Posted 3 September 2018

Dr Harriet Hall explains why the alkaline diet, and other claims of pH imbalance requiring intervention in individuals without chronic disease, is mostly nonsense. For example, does Vogel’s Multiforce Alkaline Powder claims have any merit, or are they simply marketing rubbish?

She writes:

The internet is a cornucopia of facts, some true and some “alternative” (in other words, lies). One topic that is particularly plagued by misinformation is pH. People are restricting their diet, buying alkaline water, testing their urine with pH test strips, and buying into bogus cancer cures, all on the basis of false pseudoscientific claims. Going back to basics will help us distinguish pHacts from pHiction.

Can DNA Predict Your Perfect Diet?

Nutritional genomics would mean the end of dietary guesswork, but science hasn’t quite caught up to the hype

Markham Heid The Medium

Which diet is best for weight loss: low carb or low fat?

It seems like a straightforward question — one that a single well-designed study should be able to answer. But after nearly 20 years of such studies, the debate rages on. Taken together and applied to big groups, existing research suggests the two diets are about equally effective. But at an individual level, the effectiveness of these plans varies dramatically; some people lose 50 pounds or more, while others on the same diet end up gaining weight.

If only dietitians and doctors could predict how a patient would respond to a specific diet — in terms of weight loss, but also longevity, disease risk, and other health outcomes — it would Read the rest

Quick Weight-Loss Fix? Fat Chance, As Yet Another Herbex Advert Gets Banned

No evidence to support claimed weight loss.

By Zongile Nhlapo  HuffPost South Africa 05/06/2018

The Advertising Standards Authority (ASA) has banned advertising for yet another weight-loss product from “Herbex — Fat Burn Concentrate for Men”.

The original complainant in the matter, medical doctor and consumer activist Harris Steinman, argued that a commercial by the company implied that using the products could result in weight loss‚ which was unsubstantiated and misleading.

“The European Food Safety Authority has found that‚ even at greater doses than those used in Fat Burn‚ there is no causal relationship between these products and weight loss,” Steinman told Business Live.

“Herbex Fat Burn Concentrate for Men essentially claims that diluting between 7 percent to 50 percent of a green tea bag and half a cup of coffee in one litre
