Increase Your Muscle Mass
“You should increase your muscle mass because as your muscles get bigger, your resting metabolic rate increases,” Dr. Lofton told POPSUGAR. “As you’re sleeping with bigger muscles, you burn more calories than if you’re sleeping with smaller muscles,” she continued.
Eat More Protein-Rich Foods
The second thing Dr. Lofton said you should begin doing for a metabolism boost is “increasing the thermic effect of food (how much energy it takes to burn up your food) by increasing your fiber, your carbohydrates, and increasing your protein intake.”
Eating protein-rich foods like eggs, meat, and fish have a higher thermic effect than simple-carbohydrates like cereal and low-fiber foods like bananas.
