Caloric deficit
Caloric Deficit
A Caloric Deficit (pronounced: kuh-LOHR-ik DEH-fuh-sit) is a state in which an individual consumes fewer calories than they expend, leading to weight loss.
Etymology
The term "Caloric Deficit" is derived from the Latin word calor which means "heat", and the English word "deficit" which means "a lack or shortage". In the context of nutrition, it refers to the shortage of calories or energy intake compared to energy expenditure.
Definition
A Caloric Deficit occurs when a person's caloric intake is less than the number of calories they burn in a day. This can be achieved through diet, exercise, or a combination of both. The body then uses stored fat for energy, resulting in weight loss.
