Food thermal effect refers to the phenomenon that energy consumption increases due to eating. It used to be called the special dynamic function of food.

For example,

Eating carbohydrates can increase energy consumption by 5%-6%, eating fat by 4%-5%, eating protein by 30%-40% and complex diet by 10%.

The thermal effect of food can only increase the external dissipation of body heat, but can not increase the available energy.

That is, eating is also a process of loss.
