A 500-calorie daily deficit is within the FDA's recommended safe range. At this rate, the body preserves most muscle tissue while losing primarily fat.
To achieve a 500-calorie daily deficit, the typical approach is a combination of dietary reduction (~60–70%) and exercise (~30–40%). For example, reducing food intake by 325 calories and burning 175 via exercise.
