The Science Behind Capsaicin and Weight LossHere's a look at several findings from studies on capsaicin and weight loss:
1) Capsaicin and Appetite
Upping your capsaicin intake may ease your appetite, according to a 2009 study from the journal Clinical Nutrition. In an experiment involving 27 healthy volunteers, researchers found that consuming a combination of capsaicin and green tea led subjects to feel less hungry and take in fewer calories.
Another 2009 study (published in the European Journal of Nutrition) found that capsaicin may help decrease ghrelin (a hormone involved in promoting hunger).
2) Capsaicin and Metabolism
A number of laboratory and animal studies show that capsaicin may help rev up thermogenesis (a biological process involved in burning calories). However, there is currently a lack of studies testing capsaicin's ability to boost metabolism in humans.
3) Capsaicin and Body Fat
Preliminary research indicates that capsaicin may help fight the buildup of body fat. In tests on rats fed a high-fat diet, the authors of a 2010 study from the Journal of Proteome Research found that capsaicin stimulated certain proteins known to break down fat and inhibited the actions of proteins involved in producing fat.
