Calorigenic refers to a substance or process that stimulates or increases the production of heat within the body, leading to an elevation in metabolic rate, and subsequently, an increase in calorie expenditure. The term is derived from the combination of the words "calorie" - the unit of energy derived from food, and "genic" - indicating the production or creation of a particular substance.
In the context of biology and physiology, calorigenic substances or processes can affect the activity or synthesis of enzymes, hormones, or other molecules that regulate metabolism and energy expenditure. This can occur through various mechanisms such as uncoupling oxidative phosphorylation, increasing the secretion of thyroid hormones, or enhancing sympathetic nervous system activity.
Calorigenic agents are often associated with thermogenesis, the process of heat production in the body. The stimulation of thermogenesis can result in the burning of stored energy, predominantly from body fat, to generate heat and maintain body temperature. Consequently, this can contribute to weight loss or metabolic enhancement.
Evidence suggests that certain foods, such as spicy peppers, caffeine, or green tea, possess calorigenic properties. Additionally, specific physical activities, such as high-intensity exercise, can increase the calorigenic effect by raising the metabolic rate for an extended period after completion.
In summary, the term calorigenic signifies a substance or process that promotes heat production and elevates metabolic rate, leading to increased calorie expenditure.
