How to find a calorie deficit that fits your weight loss goal

The same deficit can produce different results Expanding on the above example, if the adults eating 500 fewer calories than before start from comparable positions, then they will likely lose comparable amounts of body weight, even though it will likely not be a pound per week.

These two bodies function differently, require different amounts of calories to maintain their current weight, and have a different body composition in terms of fat and lean tissue.

It reflects changes in body composition as you lose weight, it includes metabolic adaptation and it shows how a calorie intake that initially produced a given weight loss may produce a smaller loss later on.
