Thermogenesis is the process by which the body produces heat, playing a vital role in weight loss and energy expenditure. It is divided primarily into three types: obligatory thermogenesis, which is related to metabolic processes; adaptive thermogenesis, which responds to environmental factors like temperature; and diet-induced thermogenesis, associated with the digestion and processing of food. By increasing thermogenesis, individuals can enhance calorie burning, even at rest. Factors affecting thermogenesis include body composition, diet, and physical activity levels. Therefore, strategies to boost thermogenesis—such as strength training or consuming specific foods—can be beneficial for weight management and metabolic health.
