Calorie Deficit
A Calorie Deficit (pronounced: /ˈkaləri ˈdefəsət/) is a state of the body where the energy intake from food is less than the energy expended in the body's metabolic and physical activities.
Etymology
The term "Calorie Deficit" is derived from two words. "Calorie" is a unit of energy that comes from the Latin word calor which means heat. "Deficit" comes from the Latin word deficere which means to lack or be in want of.
Definition
A Calorie Deficit occurs when a person consumes fewer calories than their body needs to maintain its current weight. This deficit can be achieved through diet, exercise, or a combination of both. The body then uses stored fat for energy, leading to weight loss.
