Before you scarf down meal number one, get moving: Working out first thing in the morning can help you lose 20 percent more fat than exercising after breakfast, according to a 2013 study in the British Journal of Nutrition. For a quick sweat session, try this fat-burning HIIT workout that includes challenging moves like squat jumps and lunges, but can still be done in the comfort of your living room. The best part? It takes just 10 minutes to complete.
This may explain why the fat-burning effects of eating more protein were confirmed in a study published in the American Journal of Physiology. One group was fed a high-protein diet (just over 1 gram per pound of body weight per day) while the second group consumed an amount closer to the lower recommendation of the RDA (recommended dietary allowance). The group eating the higher-protein diet burned the most fat.
