Green Tea

Green Tea is very popular amongst health and fitness enthusiasts in recent times. Especially as it has been found that when combined with caffeine, it can boost your metabolism far beyond what caffeine can do alone.
Studies have shown that it can increase your metabolism to the point of burning an extra 200 calories a day without added exercise. 500mg of Green tea is perfect in a fat burner.

Rest assured we have pulled all the latest research and science on Green Tea together in the index and made it so it’s easy to understand in the context of the product you are looking at.

Whilst it’s great to have a product that looks amazing and works – Instant Knockout and Grenade we are looking at you, the ingredients are the things that will get you shredded.

#2 Grenade Thermo Detonator


What our review said:

A fairly good blend let down by Bitter Orange Peel. If we could go on looks alone Grenade would be #1. Ultimately though, it’s just not as well thought out as Instant Knockout and won’t get you as good results.

  • Only available direct

#5 Thermaxin Thermo Enhancer

A very affordable fat burner that uses some good doses of natural ingredients. It is a little under dosed so can’t compete with the top 3, but for affordability and potential to work over a long period it’s not bad.

  • Will boost metabolism and burn away some fat


  • Needs to be supplemented for longer periods

#7 Warrior Blaze Fat Burner


What our review said:

It’s supposed to be one of the strongest, but ultimately is just a bit risky. This is for the hardcore fitness enthusiast and even then it may not work or be too strong. Plus it’s quite expensive.

#9 Optimum Nutrition Opti Lean Fat Burner


What our review said:

A great metabolism booster, but not a very good general fat burner. High levels of stimulants may cause unwanted side effects too. Opti Lean is a fairly safe bet, but don’t expect results to be as good as our number #1 fat burner.


  • Guaranteed metabolism boost
  • Some fat burning properties
  • Big trusted company


  • Slightly over priced
  • Limited ingredients profile
  • High chance of side effects

#10 Muscletech Hydroxycut Platinum


What our review said:

A solid supplement that is packed full of essential vitamins and minerals. It’s fat burning effects won’t be huge, but supplementation will be safe and you should get good results over time. Muscletech’s Hydroxycut Fat burner range is hit and miss, but this is one of the better options.


  • High doses of key vitamins and minerals
  • Probiotics
  • Widely available


  • Not a through and through fat burner
  • Over complicated
  • Can be expensive

Full Review

#11 Cellucor P6 Ripped


What our review said:

Cellucor have made a male orientated fat burner with P6 Ripped. We liked it because it does have some elements that can help with increasing testosterone (and reducing belly fat) but also uses sizable doses of key fat burning ingredients too. There is still room for improvement however.


  • 2 Supplements in one
  • Looks incredible
  • Caffeine and Cayenne are proven ingredients


  • Very expensive for the amount of ingredients
  • Not a focused, pure fat burner
  • Some ingredients may not work
  • Proprietary blend

#12 Unaltered Athletics Fat Burner


 What our review said:

A solid looking fat burner that has a huge 5 capsule dose. There is a high risk of side effects though, so be wary. They could have also included more thermogenic elements than they did.


  • Good solid ingredients
  • High dose
  • Trusted company



  • Contains synephrine
  • Could cause side effects
  • 5 capsules per day could be annoying

Starting a Diet in 2018 – How to Stick to it

Having one of the top and proven fat burners ready in 2018 is all well and good.

But for a large proportion of these supplements to work effectively you need to be ready to nail down a diet too.

With January fast coming up preparation is key.

You’re reading this because your goal is weight loss. Now to ensure you lose a good amount of weight you need to be putting yourself in a calorie deficit.

Calorie Deficit = Burning off more than you take in

This is the simple rule of losing weight, and one you need to follow to ensure you are successful with any fat loss program.

Choosing a Diet

Like we said, there are hundreds of diet plans and workout guides out there, some are better than others.

We’d be ALWAYS inclined to choose a diet plan and workout guide that work WITH each other to promote fat loss.

You can see our favorite video based, comprehensive workout plan here.

Or alternatively you can get loads of free good ones over at bodybuilding.com.


Steve Cooks 8 Week training plan includes a nutritional guide, program overview, training overview. This is a good and essential guide if you are looking to build up some muscle and symmetry whilst also cutting back that fat.

Sticking to your New Year Diet

It’s easy to find a diet, but the hard thing is sticking to one. With so many people giving up on their new year weight loss plans, it’s frustrating to watch and probably even more frustrating to live it.

The simple way to stick to it is constantly remind yourself of what you are looking to achieve. Put notes all around the house and generally don’t give it. Telling your friends what you are going can offer a bit of positive reinforcement too.

Before you start your diet and workout program (which can be supported with a fat burner) we’d recommend you use a calorie calculator to figure out what you should be aiming to burn off each day.

Calorie Needed Per Day:

You Must Intake The Following Daily
