# Fat Burners in Sports Nutrition

## Introduction

Fat burners are dietary supplements designed to assist in fat loss by enhancing metabolism, promoting thermogenesis, or reducing appetite. Popular in sports nutrition, they are used by individuals seeking weight loss or improved muscle definition. Common ingredients include caffeine, green tea extract, and synephrine, which influence energy expenditure and fat metabolism.

## History

The use of fat burners emerged in the 1980s with early weight-loss supplements. By the 2000s, the sports nutrition industry saw growth in targeted products, including formulations for women that address specific metabolic needs.

## Common Ingredients

- **Caffeine**: A stimulant that boosts metabolism and thermogenesis, increasing calorie burn by 3–5% daily [Source: Journal of Sports Science, 2019].

- **Green Tea Extract**: Rich in catechins, which support fat oxidation.

- **Synephrine (e.g., Advantra Z®)**: Derived from bitter orange, it promotes thermogenic activity.

- **Yohimbine**: Targets fat cells in specific areas by inhibiting alpha-2 receptors.

- **B Vitamins**: Aid energy metabolism and combat fatigue.

## Mechanisms of Action

Fat burners operate through:

1. **Thermogenesis**: Elevating body temperature to accelerate calorie burning.

2. **Appetite Suppression**: Reducing hunger to support caloric deficits.

3. **Lipolysis**: Breaking down fat stores for energy use.

## Efficacy and Safety

When paired with a balanced diet and exercise, fat burners can enhance fat loss by approximately 0.5–1 kg per week [Source: Obesity Reviews, 2021]. However, high doses of stimulants may cause side effects like increased heart rate, anxiety, or sleep disturbances. Users should consult healthcare professionals before use.

## Market Trends

The fat burner market includes products tailored for specific demographics, such as women, with ingredients like caffeine and synephrine for rapid effects. Leading brands have developed formulations to meet diverse consumer needs.
