I’ve heard about this thing so many times. How is it possible to eat something, but still burn calories?
In: Biology
Even at rest, a body needs energy for all it does. This includes breathing, sending blood through the body, keeping hormone levels even, and growing and repairing cells. The number of calories a body at rest uses to do these things is known as basal metabolic rate, also called basal metabolism.
Basal metalbolic rate can vary from person to person but is essentially the calories burned by the body by just living. So to simplify, if weight loss or gain is just calories in vs. calories out if all you eat in a day is a meal that’s 400 cals but your BMR burns 1200 cals, you would be in a caloric deficit of 800 cals that day or negative 800 calories.
