Reducing calories always causes you to lose weight. Yet two factors control whether you'll lose mostly body-fat or muscle tissue as well; how many calories and how much protein you eat. Eating too few calories affects your ability to exercise at high levels of intensity, as well as slows your metabolic rate (an important factor in losing body-fat). Fasting or starving yourself will not only cause your body to burn lean muscle mass for fuel, but could also put you into a state of ketosis. When you drop your calories from fats and carbohydrates, protein becomes a reserve fuel source (in addition to the body-fat you'll be burning). If you eat too little protein each day, your body may use up body protein, causing a loss of muscle, a slower metabolism and a softer appearance.

Low-carb diets deplete muscle-glycogen levels to trigger the body to rely on fat for fuel. High-intensity aerobics further depletes glycogen levels to burn away more unwanted fat. For best results, do cardio before you eat (when glycogen levels are lowest). Stay on a low-carb diet for two weeks. Then on the 15th day, increase carb consumption to two or three grams per pound of bodyweight and decrease protein to one gram per pound of bodyweight. You can follow a low-carb diet for eight or nine weeks, as long as you take a break from it for one day every two weeks to give your body a mental and physical relief.

Shown below are diets that could be used by either male or female to reduce body-fat, and maintain lean muscle. Substitutions of certain foods are acceptable, if they're in the same food group and roughly the same categorized gram and caloric count.
