I’ve never seen as much confusion and disagreement around weight loss supplements as with fat burners and fat metabolisers.

While they’re both suitable for dealing with weight issues and your BMI, it’s important to understand that the ingredients function in a very different way.

That makes fat metabolisers and burners two very different supplements, and deciding on the right one can often lead to mistakes and a waste of money.

Let me explain some basics first.

What Are Fat Burners?

Fat burner supplements are dietary products that combine natural ingredients that cause your body to process more body fat through increased thermogenesis.

This is a process that causes your body temperature to slightly rise by using energy stored in fat.

However, keep in mind that even the best fat burners won’t help you lose weight while planting your body on the couch, watching Netflix, and eating your way through a box of donuts.

You still need to get into healthy diet habits and an exercise routine for a fat burner supplement to have any effect.

What Are Fat Metabolisers?

Fat metabolisers provide weight loss support in two different ways.

There’s one kind that works on your digestive system to help it break down fat faster and help your body transform the fat into energy.

The more common one is a supplement that has ingredients like acetyl l-carnitine that play a role in delivering fatty acids to muscle fibers, where it’s the fuel for increased energy levels.

Ultimately this means that your body becomes more effective at transforming fat into energy rather than unwanted love handles.

Sometimes, fat metabolisers and burners have overlapping ingredients, but it’s important to understand that they trigger and support different natural processes.

2 Main Differences

Before tackling the right choice of weight loss supplements, let’s take a look at three areas where you will find some differences.

1. Benefits

You’re probably familiar with the general benefits of fat burners, including:

Fat burning

Good fat burners mainly focus on helping your fat loss efforts by burning off a few extra grams of fat every day, even when you’re not physically active.

Appetite suppression

In addition to fat-burning benefits, they also tend to contain appetite suppressants that help you avoid snacking.

Fat metabolisers, on the other hand, are mainly involved in transporting the broken down fat cells to muscles and organs, where they provide increased energy levels.

That’s why the weight loss industry generally refers to fat metabolisers as causing indirect fat reduction, as they play a more supporting role.

2. Side Effects

The good news is that both types of weight loss supplements generally have very limited side effects.

On the fat burner side, the most common issue is jitters from the stimulants like caffeine.

This mainly happens to people who also drink a lot of coffee and is avoidable.

Fat metabolisers also have a generally safe ingredient list, but some folks with a sensitive stomach might experience some nausea from ingredients like L-carnitine, CLA, and choline [1].

Metabolism Effects

Fat burners directly target the flabby stuff and love handles that you want to get rid of by triggering thermogenesis [2].

“Thermogenesis, literally defined as heat production, is an important physiological variable as well as a normal by-product of metabolic processes.” -ScienceDirect.com. 

What fat burners don’t do is help your body transport the broken-down fat cells to where they are needed.

That’s where fat metabolisers come into play, and depending on the ingredients, they may help to remove a bottleneck for increasing the rate of fully metabolising fat into energy.

Making The Right Personal Choice

Here’s how I would suggest approaching these supplements.

In the majority of cases, I wouldn’t suggest just taking fat metaboliser supplements.

They tend to provide the best effects once the fat cells from love handles have been released but don’t directly target that release.

Fat burners are a good option to help with weight loss and directly targeting fat storage.

Once you find a good fat burner, I would suggest adding a metaboliser to further boost your metabolism and its end-to-end processing of fat.

Just make sure you avoid supplements with overlapping ingredients, as that’s where you could run into negative effects.

Which One Would You Try: Fat Burner or Fat Metaboliser?

At this stage, you should understand why a fat burners vs. fat metabolisers debate ignores the fact that they have a significant difference.

When it comes to weight management, these two supplements generally work well together to boost your metabolism with natural ingredients.

That’s why you should start by finding a suitable fat burner and then later adding a metaboliser into your weight loss stack.
