Do this: Most guys who are fairly active and exercise regularly burn about 18 calories per pound of bodyweight or more per day. On that basis, a 200-pounder would consume 3,600 calories daily. To start dropping body fat, reduce your calories to between 14-16 per pound of bodyweight per day on workout days, or 2,800-3,200 calories daily. On nonworkout days, drop to about 12 calories per pound per day (2,400 calories for the guy who's 200lbs).
When food intake and carbs are low, leptin levels will lower. This will send signals to the body that energy intake is low and the metabolism must be lowered to compensate for the lack of incoming energy. When carbs are kept in the diet it will help keep elevated levels of leptin and other fat burning hormones even when total calorie intake is low.
3. Caffeine: Coffee is good for more than just a jolt in the morning. A study in the International Journal of Sport Nutrition and Exercise Metabolism found that consuming caffeine an hour before you hit the gym can help you burn about 15 percent more calories than normal. What’s more, other research has found that sipping on the stimulant before the gym can help you eat fewer calories afterward.
“Speed is key—move, walk, or run a little faster and you’ll burn more total calories,” says Kravitz. In fact, changing up your walking pace quickly and frequently can help you melt up to 20% more calories, compared with maintaining a constant speed, according to a 2015 study from The Ohio State University. Try speeding up for 30 seconds, then walking at a comfy pace for three minutes.
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.
