Herbex is flighting an advert on MNET during the Carte Blanche program for Herbex Fat Burn for Men.
In the form of an animated cartoon, it shows an overweight man crashing off a roof. The inference and promotion for Herbex Fat Burn for men range is the clear goal of this advert, therefore making the claim that the Herbex Fat Burn for Men range can result in weight-loss.
Herbex Fat Burn Concentrate for Men attributes its claims to three main ingredients: Guarana, Green tea leaves and Siberian ginseng.
Natural Medicines Comprehensive Database (NMCD) is a very credible source for information on these ingredients. ‘Experts’ for Herbex have previously relied on this source to argue the case, falsely, for other Herbex products.
NMCD states for the effectiveness of Green tea for use in obesity/weight-loss as “INSUFFICIENT RELIABLE EVIDENCE to RATE”. But worse, Herbex uses this ingredient in massively smaller dosages than studied!
I had the dosages of the ingredients of Herbex Fat Burn tested for by a prominent local university.
The directions for this product is to “Dilute 25 ml of concentrate in 1 litre of cold water. Mix well. Drink throughout the day”.
According to our laboratory measurement for the amount of green tea in this product, it contains between 7% to 50% of a bag of green tea.
In other words, Herbex Fat Burn claims that around half a bag of green tea leaves, with the addition of guarana and Ginseng, added to 1 litre of water to be drunk throughout the day, will result in weight loss. But wait, there is more!
The second ingredient, Guarana, contributes caffeine. Herbex tells us that 50 mg of Guarana is contained in every 25 ml to be added to 1 litre of water. Guarana seeds contain around 4.7% caffeine, so 1000 mg of guarana would contain on average 47 mg of caffeine. Therefore 50 mg would contain 2.35 mg caffeine. A cup of coffee contains on average 94.8 mg caffeine.
In other words, Herbex Fat Burn claims that caffeine found in about 3% (7.5 mls) of a cup of coffee, with the addition of half a bag of green tea leaves and Ginseng, added to 1 litre of water to be drunk throughout the day, will result in weight loss. But wait, there is more!
The third ingredient is Siberian Ginseng. It has no evidence of use for weight-loss, but Natural Medicines Comprehensive Database (NMCD) states that Siberian ginseng has been traditionally used as an appetite stimulant! (Herbex claims that “Ginseng is known to increase energy levels which helps to stimulate the metabolism”. There is no evidence for this claim)
In other words, Herbex Fat Burn claims that a mixture of about half a bag of green tea leaves, caffeine found in 7.5 mls of a cup of coffee, and Ginseng traditionally used to stimulate appetite, added to 1 litre of water to be drunk throughout the day, will result in weight loss.
In 2012 a company making a product containing green tea and guarana, at high dosage levels, asked the European Food Safety Authority for permission to market the product for weight-loss. Using much greater dosages than found in Herbex Fat Burn, their conclusion was: “The Panel concludes that a cause and effect relationship has not been established between the consumption of a combination of Paullinia cupana Kunth (guarana) and Camellia sinensis (L.) Kuntze (green tea) extracts and a reduction in body weight”.
So it appears that the only weight-loss you will experience with Herbex Fat Burn for Men is that of less money in your pockets.
