Brazilian Slimming Tea Review 

First impressions

Brazilian slimming tea hits all the buzzwords that we see in dietary supplements: it claims to be an ‘all-natural’ diet tea focusing on the inclusion of various popular teas (all of which have a common progenitor) and raspberry ketones. Teas and ketones are two of the “hottest” weight loss ingredients on the marketplace, being included in a wide variety of supplements that we’ve already looked at. Teas are sold in supplies from 15 days to 90 days, marketed as a package with teas for 4 different times of day. The beauty of tea-based supplements is that they are usually incredibly safe when consumed in reasonable quantities and possess fantastic anti-oxidant and de-stressing properties.

The list of products offered also includes skin creams and “body wraps” which are aimed at improving the quality of skin and reduction of body fat in particular areas. Whilst these will not be the focus of this review, it is important to note that body wraps are a whole area of the fitness industry founded on poor science and blind optimism. Reduction of bodyfat in a single, isolated are does not fit with the body’s mechanism for fat oxidation and metabolism. We can increase the contributions of certain areas to a universal reduction in body fat, but this is achieved through altering hormonal profiles, not wrapping them in glorified cling film! We can’t comment on the skin creams but these wraps should be avoided – the teas are the only product we could even consider from this list.

Brazilian slimming tea provides a 14-day 100% money back guarantee for anyone who is unsatisfied with their order. This suggests that the company has faith in its products and has at least some level of concern for the customer’s wellbeing and was awarded a customer service award in 2013.

How effective is it?

Brazilian tea is based on a blend of 4 teas and raspberry ketone tea. These include Oolong, green tea, Pu-erh and White tea. This seems like a comprehensive blend until we realise that there are no huge differences between the teas: whilst they may contain different levels of different chemicals, they are all derived from the same tea leaves – there is nothing malicious in this, but it is worth remembering that they are fundamentally the same thing and green tea has the greatest quantity of ingredients that are active in weight loss [1]. The varieties of tea found in Brazilian slimming tea does not have a significant bearing on weight loss, but does provide a variety of health benefits. For example, white tea has the most relaxing effects [2] whereas Pu-erh has improved anti-inflammatory qualities [3].

Green tea catechins have been shown to have some positive impacts on body fat and the fat-oxidation process, but this has been demonstrated to be as small as 5.7g of body fat per cup of green tea [4]. This is an approximate 50mg of EGCG – even with the 4-a-day schedule provided by Brazilian slimming tea, this is an incredibly small amount of effect (with a generous estimate of 24g of fat burned in a day). This is an incredibly small change and, whilst it does technically suggest that there are some positive effects associated with the drinks – the problem is that this is also seen from regular forms of green tea. Your household brand of green tea may be just as effective for fat loss and anti-oxidant effect as Brazilian slimming tea!

As stated above, the introduction of raspberry ketone to various dietary supplements and products has been popular recently as they have gained a cultural status as a “fat burner”. The problem with the inclusion of this product is that it simply does not work: experiments that have demonstrated positive effects are performed either on fat cells in vitro or on rats in concentrations that are far beyond the amount we might consider reasonable for human consumption [5]. For example, example.com suggests that “The concentration which is required to have fat burning effects is astronomically high” – as high as 62g a day for an adult weighing 113kg.

The question as why we shouldn’t consume 62g of raspberry ketone per day demonstrates another problem with the inclusion of raspberry ketone in dietary supplements: raspberry ketone has been used for its molecular similarities to synephrine – a stimulant. The suggestion that raspberry ketone works by mimicking stimulants is part of its appeal (stimulants tend to promote weight loss) but if this is the case, consumption of this quantity would involve some profound side effects. From both practical and safety perspectives, the consumption of this quantity of raspberry ketones would be both difficult and potentially dangerous.

Questionable claims and disclaimers

Brazilian slimming tea makes a few false or misleading statements on their website. Firstly, they claim that their products allow for weight loss without the use of caffeine – this is clearly false as green teas have been noted to contain caffeine [6] which is associated with the increased basal metabolic rates associated with teas. Secondly, they claim that their products are all-natural whilst also containing raspberry ketone – the problem with this claim is that raspberry ketones are synethically produced and cannot be extracted from raspberries in the quantities associated with effective weight loss and must be synthetically-produced [7].

Additionally, the company claims that their products are contrasted with “torturous cleanses or diet pills full of chemicals” – this is to suggest that Brazilian slimming tea does not contain chemicals. The obvious response to this is laughter – all foods are full of chemicals by definition and the inclusion of synthetically produced raspberry ketones suggest that it would not even be possible to differentiate the product based on “natural” chemicals as opposed to those produced through industrial processes.

When we begin to look at the value of a dietary supplement for our lives, it is important to look for evidence-based claims that are supported by a variety of scientific sources and clinical evidence. This is, after all, why we review these products: to provide a more balanced scientific appraisal of their contents and efficacy. It is worrying, then, that the Brazilian slimming tea website includes the following disclaimer in the footer: “Representations regarding the efficacy and safety of Brazilian Slimming Tea have not been scientifically substantiated or evaluated by the Food and Drug Administration. Results may vary.” (our italics). That a company can make scientific claims about its product whilst simultaneously acknowledging that it has no substantive science to support its claims is preposterous.

However, our favorite preposterous claim is included in the otherwise-reasonable “eating plan”: “Lemon dressing, olive oil and vinegar makes the best salad dressing, it detoxifies and is zero calories!”. To anyone with even a rudimentary understanding of nutritional science, the problem with this statement should be obvious: not only is olive oil not zero-calorie, it has the highest possible calorie content of any food in existence. 100g of olive oil contains 900 calories because fats are 9 calories per gram and “oil” is another word for pure fat. Clearly, whoever wrote the eating plan had a lapse of sanity here!

The value question: is it worth the cost?

Even if Brazilian slimming tea had the effects that it claims, it does not seem obvious to us that it would justify the costs. A 90-day supply of tea has an RRP of $300 – this seems excessive given that the different ingredients are widely available relatively inexpensively. A similar supply of raspberry ketones can be purchased for less than $20. Whilst some of the included teas can be more expensive (mostly Pu-erh, due to the associated fermentation process), 360 green tea bags can be purchased at a cost of less than $18. Where the price tag of $300 comes from we are not sure – though we can definitively state that it does not reflect the cost of clinical trials and research!

Given that the effects of additional teas have already been shown to be minimal for weight loss, and that green tea is already an effective anti-oxidant, there seems to be very little to commend Brazilian slimming tea over the combination of these products by themselves. When we consider that raspberry ketones don’t have a significant effect on weight loss, we could do without even purchasing the capsules. With this in mind, it is clear that we could effectively replace the Brazilian slimming tea with regular green tea without any serious differences in the weight loss effects experienced.

Brazilian slimming tea still fails our basic value test, which is as follows: does it justify the costs if we are already on a balanced diet? This does not seem to be the case with this glorified tea – an individual on a balanced and nutrient-dense diet may benefit from the consumption of green tea (a balanced diet will make the best use of the nutrients included in green tea) but there is no reason to believe that Brazilian slimming tea is more effective than regular tea. As such, it seems that the question of value is a resounding no: there is very little positive value added to a balanced diet from the inclusion of this product.

Closing remarks

It’s just expensive tea.
