How to Lose Weight, Not Muscle
Losing weight and gaining muscle can often seem at odds. You’ve heard the classic advice: If you want to shed pounds, you have to eat fewer calories while burning more of them. If you want to gain muscle, you have to do just the opposite, increasing your caloric intake while working your muscles hard. So is it possible to attack the two most popular fitness goals at the same time? The answer is an unequivocal yes. Just follow these three simple rules.
Skip the Long Runs If you want to lose fat, don’t go the aerobic route, say researchers at Pennington Biomedical Research Center, in Louisiana. Their study comparing the weight-loss results of people who did aerobic workouts while dieting with those who only dieted found that steady state cardio (think: jogging, stationary cycling, rowing) added almost nothing to the weight loss equation. When it comes to shedding pounds, you want to be the hare, not the tortoise: A 2011 Australian study found that shorter, tougher workouts (e.g., sprints, intervals, high-intensity strength circuits) consistently resulted in significant fat loss. Added bonus: Working out at a high intensity specifically targets abdominal fat—the most insidious kind that wraps around your internal organs, increasing the size of your belly and your risk for cardiovascular disease, diabetes, and even cancer.
Don’t Starve Yourself If you want to lose fat, you have to cut your caloric intake. But if you also want to also maintain (or even build) muscle, cutting a little works better than cutting a lot, according to Norwegian scientists. Their study found that strength-training athletes who cut calories by 30 percent saw no change in muscle mass, but those who cut calories by just 19 percent were able to increase their muscle mass while also leaning out. Shoot for losing no more than 1 percent of your bodyweight—or roughly 1 to 2 pounds—per week, suggest the researchers.
Prioritize Protein You need protein to build muscle. If you want to lose fat at the same time, you may need even more: A 2016 study found that overweight men on an intense fitness routine and a calorie-restricted diet were able to gain muscle over a 4-week period—but only if their protein intake was high. Protein should make up slightly more than one-third of your total caloric intake. Don’t want to do the nutritional math? Eyeball it: Meat, fish, poultry, and other protein should take up about a third of your plate at each meal.
