Foods known to boost metabolism include those high in protein, such as lean meats, legumes, and dairy products. These foods require more energy for digestion, known as the thermic effect of food. Spicy foods, particularly those containing capsaicin, can temporarily increase metabolic rate. Green tea and coffee, due to their caffeine content, also promote a slight increase in metabolism. Incorporating fiber-rich foods helps maintain a healthy digestive system, which is crucial for efficient metabolic function. Together, these dietary choices can support greater energy expenditure and weight management.
