Breakfast revs your metabolism
Breakfast has no more special effect on metabolism than any other meal of the day, according to Nadler. Weight maintenance is more about the quality of the food and managing blood glucose levels, she explained. Thermic effect of food (TEF), which is the increase in metabolic rate as a result of breaking down the food you eat, occurs after every meal, not just the first one in the morning.
High-intensity interval training speeds up metabolism
High intensity interval training (HIIT), which are workouts that include short bursts of intense exercise alternated with short breaks, have been very popular in the fitness industry for years. HIIT increases the number of calories burned and reduces fat, but that doesn’t necessarily translate to faster metabolism. Metabolism is influenced by muscle mass, and to build muscle you need to do strength training.
