The more muscle you have, the more calories you burn—no matter what you’re doing. Hitting the gym helps you build muscle but eating protein keeps your gains from breaking down and slowing your metabolic rate as a result. Protein needs differ by individual, but typically consuming 0.8 to one gram of protein per kilogram of body weight per day should be sufficient enough to fuel weight loss, says Leah Kaufman, MS, RD, CDN, a New York City-based Dietitian. For a 130-pound (59 kilograms) person, that would equal between 46 and 58 grams of protein. Research has found that because protein is more difficult for the body to break down and digest than other nutrients, it can increase post-meal calorie burn by as much as 35 percent. Aim to incorporate some protein into every meal and snack throughout the day.
Although it’s true that egg whites are low in calories, fat-free, and contain most of the protein found in an egg, eating the entire egg is beneficial to your metabolism. The yolk contains many metabolism-stoking nutrients, including fat-soluble vitamins, essential fatty acids and—most significantly—choline, a powerful compound that attacks the gene mechanism that triggers your body to store fat around your liver. Worried about cholesterol? New studies have found that moderate consumption of two whole eggs per day has no negative effect on a person’s lipid (fat) profile and may actually improve it.
When you're trying to ramp up your metabolism, eating fats might sound scary — but you just have to eat the right kind. Focus on a balanced diet of protein, carbs, and healthy fats like avocados, nuts, and olive oil to see a change. "I told my friend to start her day with high-fiber cereal, plain yogurt, and a handful of walnuts, or a hard-boiled egg and a slice of whole-grain toast topped with avocado. Then eat this same balance of protein, carbs, and fat for lunch and dinner," says Eugenia Gianos, M.D., co-director of the Center for the Prevention of Cardiovascular Disease at New York University Langone Medical Center. "She felt full between meals, had fewer cravings, and because good fats and fiber work in tandem to boost metabolism, she was able to drop the extra pounds and keep them off. It's a strategy I've seen work over and over again in my practice."
The easiest 350 calories you'll ever burn: Exercise is obviously important, but regular daily activity known as "NEAT" (nonexercise activity thermogenesis) is equally essential for a healthy metabolism. Small movements such as stretching your legs, taking the stairs, even just standing to talk on the phone increases your energy expenditure and can add up to an extra 350 calories burned a day.
