One meals calorie (kcal) represents the power required to warmth one kilogram of water by one diploma Celsius. Whether or not you might be energetic or at relaxation, your physique continuously wants power. If it doesn’t use all of the power you devour, it shops the surplus primarily as physique fats, contributing to weight acquire.

Thermic impact of meals (TEF): The energy expended in digesting, absorbing, and processing the vitamins out of your meals.
Exercise power expenditure (AEE): Energy burned by bodily actions like exercising, strolling, or performing day by day chores.

This leads on to weight reduction, particularly when sustained over time.

A average and secure calorie deficit is commonly round 500 energy a day. This stage is broadly beneficial as a result of it usually interprets to about one pound of fats loss per week. That is contemplating that roughly 3,500 energy equals one pound of physique fats. Sustaining this deficit persistently permits for regular, wholesome weight reduction with out inflicting excessive starvation or fatigue.
