Frequently Asked Questions
What are fat burners?

Fat burners are supplements designed to increase your basal metabolic rate and energy expenditure, helping you burn fat more efficiently​. They often contain ingredients like caffeine, green tea extract, and L-carnitine, which boost metabolism and enhance fat oxidation.


Additionally, fat burners can help suppress appetite, improve energy levels, and enhance workout performance, making it easier to achieve weight loss and fitness goals.

What ingredients are commonly found in fat burners?

Some of the most common ingredients in fat burners include the following ingredients, used for their thermogenic effects and ability to aid in fat loss:


  • Caffeine: Increases basal metabolic rate and energy expenditure.
  • Ephedrine: Enhances fat loss and suppresses appetite.
  • L-Carnitine: Stimulant-free amino acid that helps use fat stores for fuel and maintains heart health.
  • Conjugated Linoleic Acid (CLA): Burns stored fat for fuel and aids muscle recovery.
  • Diuretics: Help reduce water retention for a more defined look.
Can I take fat burners if I'm sensitive to stimulants?

If you are sensitive to stimulants, you can choose stimulant-free options. Many fat burners contain ingredients like caffeine, which can cause jitteriness or increased heart rate. Non-stimulant weight loss supplements are a great alternative to stimulant-based fat burners and thermogenics. They provide sustained energy, forcing your body to use its own fat stores as a fuel source.


A popular non-stimulant fat burner is an Amino Acid called L-Carnitine. L-Carnitine regulates protein balance and helps maintain a healthy heart. 


Conjugated Linoleic Acid (CLA) is another popular non-stimulant weight loss supplement. CLA encourages a positive fat balance by burning stored fat for fuel, supporting muscle recovery, and promoting a healthy immune system.


Bodybuilders and figure show contestants use diuretics to help draw excess water from between their muscles and skin. Diuretic supplements help competitors strive for the most muscular and hardest look they can possibly achieve.

Are there any side effects of taking fat burners?

The main side effects of fat burners come from stimulants like caffeine. If you notice any side effects, talk to your doctor. The most common side effects associated with the use of fat burners are:


  1. Increased heart rate: Often caused by stimulants like caffeine.
  2. Insomnia: Difficulty sleeping due to stimulant content.
  3. Jitteriness and anxiety: Common with high stimulant doses.
  4. Digestive issues: Such as nausea or upset stomach.
  5. Dehydration: Especially with diuretic ingredients.
How quickly can I see results from using fat burners?

Unfortunately, this is more of a "how long is a piece of string" situation, as a few variables impact the time it takes to see results. These include:


  • Diet and Exercise: Essential for effectiveness
  • Consistency: Regular use as directed
  • Individual Differences: Metabolism and overall health


Because of these factors, results from fat burner supplements can vary, but generally:

  • Initial Changes: 1-2 weeks (increased energy, reduced appetite)
  • Visible Weight Loss: 4-6 weeks
  • Substantial Results: Several months
Do I need to cycle fat burners?

Cycling fat burners is generally recommended to maintain their effectiveness and reduce the risk of side effects. Cycling involves taking the fat burner for a set period, followed by a break. This helps prevent your body from getting used to the supplement, which can reduce its effectiveness. Additionally, it reduces the effects associated with prolonged use.

Here’s an example of a common cycle:

  • Use: 4-6 weeks on
  • Break:  2-4 weeks off
What is the role of green tea extract in fat burners?

Green tea often plays a key role in fat burner supplements due to its potential weight loss benefits. It contains catechins, particularly EGCG (epigallocatechin gallate), which can enhance metabolic rate and increase calorie burning. Additionally, green tea can improve the body's ability to burn fat, especially during exercise.


Beyond its fat-burning properties, green tea offers antioxidants that help protect cells from damage and support overall health. Some studies also suggest that green tea can help suppress appetite, contributing to reduced calorie intake. However, for maximum effectiveness, you should combine green tea with a balanced diet and regular exercise.
