What is thermogenesis?

Thermogenesis is a natural process in our body that generates heat by burning calories.

The word comes from thermo, meaning heat, and genesis, meaning generation or production.

Thermogenic pre workouts vs other pre workouts

Life is always busy, you go to work or school if you are a student, you get back home and you are getting yourself ready to go to the gym and blast a workout, right? But unfortunately, you are tired from work and don’t have that much energy.

On top of that, you are dieting because you have the goal of losing fat so it is making it a bit worse.

Pre workouts are designed to help with that matter. Some people lose focus and don’t have that much energy to go blast a workout in the gym.

A pre-workout gives you a boost of energy to help you power through your workout.

Fat burners, on the other hand, are a supplement that are made to increase metabolism and help you lose fat along with the diet and training.

If you are dieting and training hard but still you are not satisfied with the results, a fat burner such as a thermogenic pre-workout will be a great tool.

What are Thermogenic Pre workout Supplements?

Imagine combining two of the best supplements together, the result is legendary.

Thermogenic Pre Workouts are the supplements that combine pre workout supplements effects which are boosting energy and increasing focus with fat burning ingredients that help you lose fat and increase metabolism.

Pre workouts and fat burners will usually have similar ingredients, but each one of them adds a few ingredients to the list.

When you combine them together, they give you the effect of fat burners and pre workouts in the same supplement.

Fat burners effect is called the ” Thermogenic effect” because it works through a mechanism called thermogenesis. So now you know why we called them thermogenic pre workouts.

Thermogenesis and Fat loss

Thermogenesis is basically the mechanism of burning calories to produce heat in your body.

For example, when we are in the winter, we tend to eat more than summer because our body is trying to produce heat.

The metabolic process of thermogenesis is affected by a great number of ingredients, these ingredients increase thermogenesis in our bodies which burns more calories.

Burning calories translate to burning fat.

Our bodies don’t burn fat directly, calories are burnt first, then the body goes to the fat storage to take energy and survive.

Along with burning fat, thermogenesis also reduces appetite, which will help you lose more fat. Appetite can be a real problem for some people.

Important Ingredients In Thermogenic Pre Workouts


When we talk about pre workouts and fat burners, the most important ingredient is the caffeine. For the coffee lovers, here we go.

Caffeine is an ingredient that is found in coffee, tea, chocolate, and many products. It is an ingredient that increases focus, improves performance, and burns fat.

Even though caffeine is very important, some thermogenic pre workouts will have a dose that is so high for you.

Studies suggest that 100-400mg from caffeine is safe for everyone, but higher than that, they did not say much.

However, The dosage range is individual, you might be good off 100mg, some people can tolerate 400mg in a dose with no problem.

Capsaicin “Cayenne”

Capsaicin is one of the main ingredients in fat burners. It is the chemical substance that causes heat when you eat chili peppers.

Have you ever eaten chili peppers and not gotten a hot, burning sensation on your tongue?

Capsaicin is an ingredient that increases our thermogenesis which means more fat burning. Not only that, capsaicin can also decrease appetite helping you to eat less.


CLA is a powerful ingredient and can be in fact in an individual supplement. It is known to increase fat oxidation and let your body target your fat storage for energy first.

It also has many other health benefits other than increasing thermogenesis and fat oxidation “burning”.


Yohimbine is a strong fat burner that comes in a lot of thermogenic pre workouts. However, the ingredient is banned in some countries because of the adrenaline effect it has.

Green Tea Extract

Green Tea Extract is an important ingredient in fat burners. It contains caffeine and many antioxidants that have a thermogenic effect.

Do I need to take a Thermogenic Pre Workout?

If you have the goal of losing fat and you want to boost the process more, thermogenic pre workouts can be a great fit for you.

Also, if you have low energy levels and want a pre workout that boosts your energy and increases performance so you can train hard while dieting, you definitely need them.

When to take these Pre Workouts?

As it is named “Pre workout” supplements are taken 15-30mins before your workout.

However, thermogenic supplements burn fat any time in the day, they are best suited before workout to boost your energy and increase your performance.

Also, do not take the thermogenic pre workout at night, as it contains a high dose of caffeine and will hinder and worsen your sleep.

Consider taking it before your workout in the morning, if you train at night, find a product with a low dose of caffeine if at all.

Are thermogenic pre-workouts safe and what are the side effects?

Generally, thermogenic pre workouts are safe. However, they have some minor side effects as making you sweat more, go to the bathroom more, and the high caffeine dosage can make sleeping more difficult for you.

With that being said, some ingredients can be harmful to you if you have a sensitivity or heart disease or others, consult your doctor and tell him/her about the ingredients before taking them.
