The term thermogenesis comes from the Greek word thermos, meaning heat. All metabolic processes in animals produce heat. This is a reflection of thermodynamic inefficiency meaning animals are thermogenic. However, generally, it describes an adaptive process of heat generation. The heat produced in direct response to a meal also describes it.
Thermogenesis refers to the process of creating heat within the body. Thermogenesis is closely linked to metabolism. This is because the body burns calories in order to produce the resulting heat. There are three types of thermogenesis that occur in the human body:
- E.A.T. (exercise-associated) – Intentional muscle movement, such as exercise, causes heat production in the body
- N.E.A.T. (non-exercise activity) – Energy expended for non-sporting activities like cooking, typing, or standing.
- D.I.T. (diet-induced) – Also known as the ‘thermic effect of food.’ This refers to the calories expended in the digestion, absorption, and storage of food.
Thermogenesis can have a significant influence on weight loss. This is because it burns calories which can help you avoid a positive energy balance which is the main cause of weight gain. So, inducing thermogenesis, with a healthy diet and exercise, is an effective way to lose weight by burning body fat.
Thermogenesis uses calories to produce heat which helps to create a negative energy balance. As a result, this leads to weight loss. It is part of a complex metabolic system that’s designed to ensure your body can adapt to changing environments. Increasing your activity and consuming thermogenic substances help to increase heat production in the body. This supports other fat loss efforts. It ensures you get the best results from your hard work.
