 As of 2007 there was no evidence showing that weight loss is directly correlated with ingesting capsaicin.Well-designed clinical studies had not been performed because the pungency of capsaicin in prescribed doses under research prevents subject compliance.A 2014 meta-analysis of further trials found weak, uneven evidence suggesting that consuming capsaicin before a meal might slightly reduce the amount of food that people eat and might drive food choice toward carbohydrates.
