What the research says
Scientific studies show that certain ingredients can moderately increase metabolic rate, boost fat oxidation or help control appetite when combined with diet and activity changes. Research most often supports short-term benefits for ingredients such as caffeine, green tea extract (EGCG), protein and chilli capsaicinoids. Clinical trials generally report small to moderate effects, and consistent, long-term lifestyle habits are needed for lasting results. Safety, correct dosage and product quality strongly influence outcomes, and results vary by individual factors such as age, sex, body composition and activity level.
Caffeine: Proven to increase energy expenditure and fat oxidation in the short term. Effective doses studied typically range from 75 mg to 300 mg per serving, depending on tolerance.
Green tea extract (EGCG): Offers modest benefits for metabolism and fat oxidation, especially when combined with caffeine. Studies show small improvements in resting metabolic rate.
Protein: Higher protein intake increases the thermic effect of food and supports muscle maintenance, which helps preserve metabolism during weight loss.
Capsaicinoids (capsaicin): Found in chilli peppers, these compounds may slightly increase metabolism and reduce appetite in some people.
Berberine and certain botanicals: Emerging evidence suggests benefits for blood sugar and metabolism, but results vary and better-quality trials are needed.
Lifestyle context: Exercise, especially resistance training, adequate sleep and a balanced diet are the main drivers of resting metabolic rate. Supplements are support tools, not standalone solutions.
Safety and quality: Look for third-party testing, clear dosage information and professional medical advice if you have health conditions or take medications.
