A high-protein breakfast can impact metabolism positively by promoting satiety and supporting muscle repair. Consuming protein-rich foods in the morning can help stabilize blood sugar levels, reducing hunger throughout the day and potentially preventing overeating. Additionally, protein requires more energy for digestion than carbohydrates or fats, leading to an increase in the thermic effect of food (TEF). This elevated metabolic rate can assist in maintaining a healthy weight. Incorporating high-quality protein sources at breakfast contributes to better energy levels and nutritional balance throughout the day.
