Intermittent fasting, the practice of eschewing food for 16 hours a day or one 24-hour period a week, has been a hot topic in fitness circles the last few years. If you’re curious about trying it, stock up on some L-carnitine first. Chinese scientists found that subjects who fasted and supplemented with L-carnitine not only lost more weight but their waist circumference got smaller and they suffered fewer feelings of hunger during the experiment than those taking a placebo. They also felt less mental and physical fatigue than the placebo group. Researchers even believe that the L-carnitine conferred some protection to their existing muscle mass dur-ing the fast.
