Hot foods will fire up metabolism

True. Capsaicin, the bioactive compound that makes chile peppers exude heat, can turn your metabolism up a notch while also enhancing satiety and reducing hunger. Studies show that eating about 1 tablespoon of chopped red or green chile pepper, which is equal to 30 milligrams of capsaicin, resulted in up to a temporary 23% boost in metabolism. In another study, 0.9 grams of red pepper was given in capsule form or naturally in tomato juice before each meal. The researchers noted that the individuals reduced their total calorie intake by 10 or 16% percent, respectively, for 2 days after and still reported being full.

Tip: Sprinkle red pepper flakes onto pasta dishes and into chilis and stews; fresh chile peppers work well in salsas and add a fiery flavor to many other dishes.
