The science behind One Slender and weight loss
Your body uses more energy to digest protein compared to carbs or even fat. It’s called the “thermic effect.” And in a lot of ways, consuming more protein is like cranking up your metabolism. A protein-rich diet can also help you maintain muscle mass, so that the calories you’re burning are applied to fat—not muscle. It also causes you to eat fewer calories, feel fuller afterwards, and has even been shown to curb late night cravings for unhealthy foods. This is why One Slender is your best protein-rich option for weight loss.
