Proteins increase metabolism due to its role in preserving lean muscle mass. These macronutrients also have a greater thermal effect, that is, proteins need more calories to be digested, compared with fats or sugars.
Thermal effect of proteins
The thermal effect of food is described as the energy used by our bodies to consume and metabolize food. According to the CaloriesperHour website. com, "proteins require the highest energy expenditure, with estimates that reach up to 30%." This means that you will burn up to 30 percent of the calories in the proteins you consume only to be able to digest them.
Proteins and weight loss
When losing weight, your lean muscle mass is susceptible to being consumed for energy without having enough carbohydrates in your diet. Leucine, an amino acid found in proteins, prevents the loss of muscle mass during a period of weight loss. Since lean muscle mass requires calories to survive, consuming enough protein will help conserve your muscles and metabolism.
Proteins should be consumed in several meals throughout the day to increase metabolism and meet daily requirements. Protein sources include lean meats such as chicken, turkey and fish, as well as beans and nuts such as almonds and black beans. The appropriate consumption of proteins favors a healthy metabolism and body.
