If you ask ten people on the street what it takes to lose a few pounds, I can almost guarantee that nine of them (at least) will respond with something almost identical too “eat less and exercise more”.
Unfortunately, as most of us who have tried to lose weight know, it isn’t always so simple.
Making long term dietary changes and implementing a solid exercise regime (and subsequently, losing weight) requires hard work, dedication, and consistency. And even then, changes in our body composition don’t come rapidly.
As a result, people often look to the somewhat shady world of fat loss supplements as a way to increase their rate of fat loss.
Unfortunately, good fat loss supplements are few and far between. With some containing dangerous levels of stimulants, and others containing herbal ingredients that do absolutely nothing to help you achieve your goals, it is hard to know where to start.
Fortunately, we are here to help identify those supplements that have some merit, and those that do not.
Enter, MAN Scorch.
MAN Scorch is one of the more recent fat burning supplements to hit the shelves. Scorch is made by a USA based company called Metabolic Augmenting Nutrition (hence the name, MAN Scorch) that produce a number of different health and fitness related supplements.
MAN describes Scorch as a ‘clinically dosed fat loss solution’, that is suggested to make dieting easier by reducing hunger signals and improving mood. MAN even go as far as to suggest that Scorch can increase energy levels and improve exercise performance, while also stimulating thermogenesis and additional fat loss.
To gain an understanding of whether MAN Scorch can meet these somewhat lofty claims, we are going to take an in depth look at the ingredients within Scorch.
If you take a closer look at the ingredient list of almost any supplement advertised to have fat burning qualities, you can guarantee green tea (or green tea extract) will be listed as a key ingredient.
There is actually a very good reason for this.
Green tea has constantly been shown to have the ability to increase both fat metabolism, and resting metabolic rate in humans.
In fact, specific studies have demonstrated an increase in resting metabolic rate (the amount of energy we burn at rest) by 4%. While an increase of 4% may not sound like a whole lot, the accumulated effect of this increase in resting metabolic rate over an entire day can become quite significant .
In addition to an increase in resting metabolic rate, green tea consumption has also been shown to cause an increase in the metabolism of fat for energy by up to 17% . Put simply, green tea can increase the availability of fat as a fuel source for the production of energy, while also increasing the amount of energy we need to use to maintain our resting metabolic rate.
This creates a good environment in which fat loss is stimulated.
Oolong tea is a traditional Chinese tea that was once suggested have a number of medicinal properties (and as such is used extensively in traditional eastern medicine). Oolong tea is partially oxidised, and as such has similar characteristics to both green and black teas.
The antioxidants found in Oolong tea have shown to boost metabolic rate in a similar fashion to green tea, while also further stimulating the metabolism of fat .
Interestingly, as an additional benefit, oolong tea has also been shown to reduce the rate of fat storage within the body. These combined effects are likely to help promote fat loss over time.
Caffeine is a stimulant that works by stimulating the brain and central nervous system, reducing fatigue while increasing feelings of alertness.
When we consume caffeine, it is rapidly absorbed into the blood, where it is then broken down in the liver and shuttled around the body. It is then shuttled to the brain, where it stimulates the central nervous system, improving mood, increasing alertness, and reducing fatigue.
As an added bonus, this stimulation has also been suggested to promote weight loss.
Caffeine consumption has been demonstrated to increase resting metabolic rate by up to 11%, while simultaneously increasing fat metabolism by up to 13% . While these effects are similar to green tea, they do occur via slightly different pathways, making caffeine an excellent addition to green tea based supplements.
Furthermore, caffeine has also been shown to reduce hunger signals slightly, further aiding weight loss.
PEA (more commonly known as Phenylethylamine) is a trace amino acid found naturally occurring within the human body.
PEA an also be taken orally as a supplement, and has been proposed to increase the secretion of the dopamine and serotonin (happy hormones). As such it has been suggested that PEA supplementation can improve mood, while causing weight loss.
There is limited scientific evidence to support these claims.
Synephrine is a supplement more commonly known as bitter orange. It is a molecule that actually shares similarities to ephedrine, but acts less severely as a stimulant.
Synephrine consumption has demonstrated measurable increases in both resting metabolic rate, and fat metabolism . Syniphrine works by inhibiting specific fat storage receptors found in the adipose tissue of the human body. This causes a subsequent increase in the availability of fat to be used for energy, which can promote fat loss.
Syniphrine and caffeine promote fat loss via completely different mechanisms, as such they are best when paired together.
Ginger is one of the few spices has demonstrated positive effects on the human body. I
Ginger is full of nutrients and compounds that have a host of benefits. These compounds can have an anti-inflammatory effect on our cells. This reduction in inflammation can improve their capacity to function, increasing the body’s ability to use stored energy. This, in turn, can promote an increased rate of fat loss
Additionally, ginger has also shown to suppress appetite, which can further promote fat loss .
Isobutyryl Thiamine Disulfide is a manmade compound more commonly known as Sulbutiamine, which is extremely similar to the b-vitamin thiamine. It has been suggested to improve feelings of lethargy and fatigue, although there is no evidence to suggest this is the case.
Raspberry ketones are a naturally occurring supplement found in raspberries, which are similar to Syniphrine in their molecular makeup.
While raspberry Ketone supplementation has shown to increase the breakdown of fats for energy in rats (and subsequently, cause fat loss), there is no scientific evidence to suggest that they work in humans.
Evodiamine is an extract from the Evodia Rutecarpa, a plant that was traditionally used in Chinese medicine to increase body temperature. It is for this reason that it has been suggested to promote fat loss (through an increase in thermogeneisis).
There is no evidence to suggest that Evodiamine can promote thermogenesis or fat loss in humans.
It is also important to note that Evodiamine has also shown to inhibit blood clotting, which may become problematic in some situations.
Bioperine is actually a form of Piperine.
Piperine is an extract derived from black pepper that has been demonstrated to improve the absorbtion of other supplements in the gut. It may have merit for use in a fat burning supplement as an aid to promote the absorption of other fat burning products.
MAN Scorch contains a number of compounds that are have known fat burning effects, as such it is likely to help promote fat loss in conjunction with diet and exercise.
It is important to note that most of these are also known stimulants (that appear here in high doses), and their consumption together may induce side effects such as dizziness, anxiety, and nausea.
