Utilizing short and controlled fasts to get lean has become more and more popular. While some evidence supports it, most hypertrophy-minded people can’t swallow the idea of going that long without protein. A recent study from China shows that supplementing with L-carnitine while fasting preserves muscles mass and promotes fat burning. Subjects were give two grams of carnitine twice a day via injection. At the end of the experiment, the carnitine group lost more centimeters from their waist than the placebo group.
Additionally, those taking carnitine reported milder feelings of hunger and less intense mental and physical fatigue than the placebo group. Oral carnitine is best absorbed when consumed with carbohydrates, so take carnitine with meals before and after your fast.
