Review Overview – What does Fat Affinity Lean Burner do?

Made by Fat Affinity, this is an all natural fat burner that has been claimed to promote:

  • Burning Fat
  • Energy
  • Losing weight


But how well does it really work?

In this review, we look closer at Lean Burner to see how effective it really is.

This is what you need to know:

How are the servings?


With only 1 serving a day, there’s only so much benefit you can get out of this fat burner.

Your body can only absorb so much at a time, and the effects will only last so long.

For the best results you need to give your body a constant supply of the nutrients it needs to stay in that fat burning mode and give you day long effects and results.

What about the ingredients in Fat Affinity Lean Burner?

Not that great.

Although there are some good thermogenics in here, there are other nutrients that really let it down.

Due to a few poor choices, this fat burner runs the risk of causing side effects and is also under dosed in several places.

Here’s what you need to know:fat-affinity-lean-burner-side-effects

Cayenne Pepper

A potent thermogenic.

This chili helps to promote your core temperature which has a great fat burning benefit.

By raising the heat, the chili encourages your body to start a cool down process that burns extra calories.

This helps burn fat at no extra effort on your part.

Green Tea

One of the better thermogenics on the market.

Green Tea has been seen to help promote fat burning due to the catechins in the herb.

By promoting the fat burning hormone, norepinephrine, these catechins help your burn more calories with any extra effort.

You may even get a mild caffeinated boost.


One of the best natural stimulants there are.

Caffeine has been seen to promote metabolism and energy levels, which is exactly what you need when you’re working out to lose weight.

Not only that, it may even improve your overall performance by enhancing power output.


May help – but there’s such a small amount.

This amino acid has been seen to raise metabolism and energy levels – however it may not be dosed effectively here.

Studies have shown you need 500 – 2500mg of Carnitine for the best effects.

With only 110mg per serving – you’re definitely not getting enough.


May help improve focus, which could helps concentration in the gym.

It won’t however help fat loss.

Citrus Aurantium

One of the poorer choices in a fat burner that may cause side effects.

Marketed to boost fat loss and energy, however the studies behind it has proved very little.

And it may cause side effects when mixed with the caffeine in this product.


Nothing special here.

May help to boost blood flow, but not much else.


Not a good choice.

Thought to help impact thyroid function for fat loss, the actual results have been seen to be far more lacking.

It will have little to no effect.

Alpha Lipoic Acid

Another ineffective fat burner.

Thought to induce stimulant-free fat loss. However no real results have been documented.fat-affinity-lean-burner-results

Ingredients Bottom Line:

On the whole this isn’t the best fat burning nutrient profile.

The main problem is the side effect risks.

Citrus Aurantium is bad news, especially when combined with caffeine.

Not only that, some of the nutrients are under dosed, and not all of them support fat loss.

Side Effects

Your main problem with Fat Affinity Lean is the Citrus Aurantium.

There are endless studies of this nutrient causing side effects – especially when combined with caffeine.

It has been seen to cause the following side effects:

  • Headaches
  • Nausea
  • Dizziness
  • Raised Heart Rate
  • Risk of High Blood Pressure
  • Light Headedness

Definitely not what you want in a fat burner.
