Supplementation for Fat Loss

We live in a generation where everything is instant and quick. We go on the internet and can find any information at the click of a button (although the majority of its accuracy is questionable). There are ‘drive-throughs’ for food and we can click a button on an app summoning a Taxi at our location in 5 minutes. Whilst travelling around USA I have seen ‘drive-throughs’ for ATMs, dry cleaning, parcel pick ups and most worryingly of all… drive-through off-licenses. 

I see this culture with people trying to lose body fat. I know a lot of people buy pills and shakes hoping to find a miracle cure. Although cleverly marketed by targeting people’s insecurities, the vast majority of these claims are not supported by any scientific evidence. I have often thought about creating a supplement called ‘Placebo’ with the catch line ‘The supplement that guarantees to deliver whatever you desire; just believe and it will work’. People would definitely buy it, making me rich, and it would be actually one of the only supplements that is supported by thousands and thousands of Academic Studies. Ethically, I can’t find it in myself to do it.

Primarily I need people to understand that supplements should be just that: a supplement. Unless your training and nutrition are correct, supplements are worthless. They should form the finishing touches to your food pyramid. 

However, here are some popular supplements that are compounded with scientific evidence:

Green Tea– Contains caffeine which is a stimulant and has a thermogenic effect helping to increase energy expenditure(1). Also contains catechins; 200-300mg of EGCG (a catechin found in green tea) has shown to maintain cardiovascular and metabolic health, as well as having anti-diabetic effects(2).

Cocoa – rich in polyphenols, which are anti-aging, full of antioxidants and can subsequently lead to eating less. Cocoa has been shown to reduce blood lipids (fatty acids) reducing the risk of cardiovascular disease and can also improve cholesterol levels(3,4). Disclaimer – this doesn’t mean milk or white chocolate which is predominantly sugar, go for 75% + dark chocolate or cocoa nibs.

Carnitine – helps the body to utilise fats as energy and improves recovery by reducing circulating levels of muscle damage and suppressing ammonia levels(5). Also been shown to increase testosterone(6), a hormone associated with increased lean muscle and lower body fat percentage.

Apple-Cider Vinegar – been shown to improve serum lipid profile (levels of fats in the bloodstream) in normal and diabetic rats by decreasing circulating levels of fats and  ‘bad’ (LDL) cholesterol and increasing ‘good’ (HDL) cholesterol(7). Rats respond similar to humans during testing…especially Splinter from Teenage Mutant Ninja Turtles.

Chilli – Meals containing chillis have been shown to increase energy expenditure and fat oxidation (maybe because you have to sprint to the toilet). Regular consumption can reduce the insulin response after a meal, reducing excessive fat storage(8).

Cinnamon – studies show that it increases energy expenditure and fat oxidation, it is also fantastic at regulating insulin levels therefore reducing the bodies propensity to store fat(9)(shout out to all the diabetics amongst you). For the record Cinnamon Grahams don’t count.

Grapefruit – Studies in humans have shown that grapefruit prevents insulin driven fat storage and also increases fat breakdown(10).

MCTs (Medium chain triglycerides eg coconut fat) – increase fat transportation so that it is used as energy. Studies show that replacing dietary fat with MCTs increases fat oxidation at rest and during exercise and increases the BMR in athletes(11).

Just to reiterate my initial point, these supplements are worthless without a healthy diet and exercise. You aren’t going to make a hot chocolate with marshmallows and cream healthy by sprinkling it with cinnamon. You need to make sure you are exercising and eating well.
