Thermogenesis is the process of producing heat. It’s a key body function since it helps maintain vital organs at a safe temperature.
Thermogenesis turns food into heat. This process happens when the body shivers, but some fat tissues are able to produce heat without the shivering mechanism. These fat tissues are brown fat, which use a chemical reaction to turn calories into heat.
Besides keeping the body warm, thermogenesis helps eliminate any excess energy by burning it.
