What are the different types of fat burner?

Different fat burners work through different mechanisms to allow you to burn more fat.

  • Appetite Suppressant

Supplements such as 5-HTP have been shown in research to reduce the amount of calories we eat, even when left to eat freely. These supplements mean that it is easier for us to maintain a calorie deficit, and therefore are burning more calories relative to what we are taking in from food.

  • Thyroid Support

The thyroid helps regulate metabolic rate. Thyroid hormone issues can arise both from long periods of both over or undereating. Thyroid regulating supplements provide substances your thyroid would usually produce such as forskolin.

  • Glucose Disposal Agents (GDAs)

A glucose disposal agent formula or ingredient (such as berberine, chromium or ALA) helps transport carbohydrate from the bloodstream into the muscles. By tacking elevated blood glucose and shuttling carbs into the muscles, we can reduce fat storage, combat cravings and boost fullness, pumps and performance for improved body composition.

  • Thermogenics

Thermogenic fat burners are designed to raise internal body temperature so that our body burns more calories even at rest (essentially raising the metabolic rate). Capsaicin and Grains of paradise are examples of thermogenics you might find in your supplements.

  • Topical

Topical fat loss supplements usually work by warming the area of fat in stubborn areas, such as the stomach or hips. These supplements are great to use before cardio as they may cause more blood flow to the area, and therefore more fat breakdown in those problem areas.

What are the best fat burning ingredients?

If you are looking to purchase a fat burning formula, there are a number of ingredients that you might want to look out for that can be particularly valuable in supporting you towards your fat loss goals. While there are many of these which fall into many different categories, here are some of our favorites based on the literature and anecdotal evidence we've seen.

1. L-Carnitine

L-Carnitine is an amino acid naturally produced by the body. L-Carnitine aids the body in oxidizing (breaking down) fat into fatty acids to be transported to the mitochondria for use as fuel. L-Carnitine is available in many forms from capsules to liquids and even injection, and as a non-stimulant fat burner, stacks well with other products.

2. Caffeine

Caffeine is a commonly used stimulant that can double up as a valuable tool in your dieting phase. Caffeine increases energy so that you can burn more calories throughout the day and get yourself into a deeper calorie deficit. It can also blunt appetite and act as a diuretic, so that you are less likely to overeat and can drop some excess water weight and fluid retention. As it has a half life of around 6 hours, we'd advise taking caffeine first thing in a morning or during the midday slump.

3. Yohimbine

Yohimbe, or yohimbine is an ingredient that is on the banned list of ingredients in some countries. This is due to the fact it can interact heavily with medications, specifically neurological ones which treat ADHD and mood disorders. Yohimbe works by blocking alpha-2-adrenergic receptors that are in fat cells – these receptors normally suppress fat burning. It also increases adrenaline making it highly stimulatory. Yohimbe is partially negated by food, so it is best taken during periods of fasting. Alpha-2 receptors are found hormonally across the body – that is for men, they are found mainly in the stomach and for women they are found mainly on the glutes and hips.

4. 7-OXO

Also known as 7-Keto DHEA which has anti-cortisol mechanisms which helps to decrease body fat. The main reason this metabolite is used in fat burners is because it has been shown to increase metabolic rate during a period of calorie restriction. During a heavy diet, our BMR (basal metabolic rate) decreases, but some studies have shown that 7-OXO can counteract this, keeping our metabolic rate high so more calories are burned. Even though DHEA is in the name, it doesn’t metabolise back into this parent form so there are no androgenic effects or hormonal modulation.

5. CLA

CLA (Conjugated Linoleic Acid) is a natural fatty acid. CLA has been shown to increase rate of fat loss and might promote the breakdown of fat rather than muscle while trying to reduce body mass. CLA is a generally affordable supplement and, like l-carnitine, stacks well with other ingredients to enhance results.

8. Predator Nutrition L-Carnitine

Predator Nutrition L-Carnitine is our best value capsule carnitine supplement. L-Carnitine 'shuttles' fatty acids to the mitochrondria for use as energy. This aids fat oxidation (breakdown) and increases natural energy without stims.

Review:

'Only been using for a few weeks, but during that time I've noted an increase in how fast my body fat percentage is decreasing while changing nothing in my daily routines.'

9. Man Sports CLA Powder

CLA is one of the most popular dietary supplements for natural fat loss without side effects. Conjugated linoleic acid plays a major role in fat metabolism, particularly in relation to the oxidative cellular system.

The primary benefit of supplementing with CLA includes its capacity to alter body composition, promoting an increase in lean muscle mass and a reduction of fat mass.

10. Predator Nutrition Green Tea

Green tea works in a similar way to caffeine but is naturally sourced and lower in side effects, with additional benefits including a high antioxidant content. A green tea supplement is much more concentrated than the drink ever could be, providing benefits including supporting metabolism. Predator Nutrition Green Tea can easily be stacked with other ingredients such as L-Carnitine or CLA.

Review:

'Stacking this on my previous cut helped me to shed my body fat right down! You will get a metabolic increase as intended.'

FAQs

Do fat burners work?

An effective fat burner will work best when combined with an intelligent fat loss programme with diet, training and cardio set to place you in a calorie deficit. Fat burners work to support this through various means such as increasing energy expenditure, reducing appetite or helping the breakdown of fat for fuel.

How do fat burners help you lose weight?

Fat burner supplements work in many different ways to assist weight loss. For best results, we'd advise stacking supplements that work through different mechanisms (so long as you are not doubling up on stimulants) or using an all-in-one supplement. This will bring about the most rapid and noticeable effects.

What are the side effects of taking fat burners?

Side effects associated with fat burner use usually come from a high stimulant content. If you fear that you may be prone to these side effects, we'd suggest starting at the lowest effective dose, only taking a fat burner first thing in a morning, or looking for a non-stimulant alternative.

  • Elevated heartrate
  • Jitters and/or anxiety
  • Sweating more than normal
  • Difficulty sleeping
  • Changes to appetite/hunger

Is thermogenic fat burning safe?

To ensure that you are using your thermogenic fat burner safely, ensure that you are buying from a reputable brand/distributer. There are certain ingredients that are banned in the UK, so if you are unsure about something on the panel, always check. When taking your fat burner, ensure you follow the usage directions given on the packaging carefully.
