What it is:

Caffeine is a natural stimulant belonging to the methylxanthine class of compounds. It is found in various plant sources, most notably coffee beans and tea leaves. Caffeine is well-known for its stimulating effects on the central nervous system, which can increase alertness, reduce fatigue, and improve cognitive function. 


Caffeine can boost metabolism by enhancing thermogenesis—the process by which your body generates heat and energy from digesting food. This increased metabolic rate leads to greater calorie expenditure, which is beneficial for weight and fat loss. It also promotes the breakdown of stored fat (lipolysis) and increases the release of fatty acids into the bloodstream. This makes fat more available as a fuel source during exercise and daily activities. It has been shown to suppress appetite which also helps in reducing overall calorie intake and supporting weight loss efforts. Additionally, it improves physical performance during exercise, which allows individuals to train harder and longer, which can lead to greater fat loss over time. The stimulant properties of caffeine can enhance mental focus, alertness, and mood, which can also contribute to increased motivation and adherence to a fat loss program. 


This 2022 systematic review and meta-analysis of 984 participants across 94 studies aimed to assess the impact of caffeine on fat metabolism using various biomarkers. The findings indicate that caffeine consumption increases fat metabolism and thus is a powerful and effective ingredient in our BURNER formula due to its capacity to mobilize fatty acids and potentially in weight management strategies.
