Let’s get down to the nitty-gritty and explore how these supplements could potentially fuel your weight loss journey.

What Are Fat Burners?

Fat burners are supplements that help your body burn more fat and lose more weight. They do this by using different ingredients that boost your metabolism, increase your energy, reduce your hunger, and speed up your fat burning.

Fat burners come in many shapes and sizes, like pills, capsules, powders, and liquids. But they all have one thing in common: they help you reach your weight loss goals faster and easier.

What Do Fat Burners Do?

Fat burner products like PhenQ, stimulate your metabolism, the process that turns food into energy. They have different ingredients that work together to help you burn fat. 


Examples of popular fat burner ingredients are caffeine and green tea extract. They’re popularity stems from how they help boost your metabolism and make your body use more fat for energy.

Here’s how most fat burners work

  • Speed up your metabolism: Fat burners have stimulants like caffeine, green tea extract, and synephrine. They make your metabolism faster, so you burn more calories even when you’re not working out.
  • Break down and use fat: Fat burners have ingredients like green coffee bean extract, L-carnitine, and forskolin. They help your body break down fat and use it for energy. This is called fat oxidation, and it can make you lose fat faster.
  • Control your appetite: Fat burners have ingredients like glucomannan, 5-HTP, and chromium picolinate. They make you feel full and reduce your cravings. This can help you eat less calories and stick to your diet.
  • Boost your energy and performance: Fat burners have stimulants like caffeine and yohimbine. They give you more energy and improve your workout performance. This can help you burn more calories during exercise.
  • Increase your body heat: Fat burners have ingredients like capsaicin and black pepper extract. They make your body produce more heat, which is called thermogenesis. This can help you burn more calories by raising your body temperature.

The Science Behind Fat Burning

You need to know how your body burns fat to understand how fat burners work. 

When you eat food, your body breaks down carbs, proteins, and fats into smaller molecules for energy. Your cells use these molecules to make adenosine triphosphate (ATP), the main energy source for your body.

Fat burners boost your body’s ability to use stored fat for energy. They do this by stimulating different processes in fat metabolism. For example, caffeine makes your body break down more fat through lipolysis, while green tea extract makes your body turn more fat into energy through fat oxidation.

Different Types of Fat Burners

You have different options when it comes to fat burners. They come in different forms, like pills, capsules, powders, and liquids. Some work better before workouts, others work better throughout the day.

The types of fat burners include:

  • Thermogenic fat burners: These increase your body’s core temperature, boosting metabolism and calorie burn.
  • Appetite suppressants: They reduce hunger cravings and help control calorie intake.
  • Carb blockers: These prevent the absorption of carbohydrates, reducing calorie intake.
  • Fat blockers: They inhibit the absorption of dietary fats, reducing calorie intake.
  • Thyroid regulators: These optimize thyroid function, enhancing metabolism and fat burning.
  • Cortisol blockers: They reduce cortisol levels, a stress hormone associated with weight gain, especially around the abdomen.
  • Lipolytic stimulants: These stimulate the breakdown of stored fat cells for energy.
  • Metabolic boosters: They enhance overall metabolic rate, increasing calorie burn even at rest.
