What daily energy deficit is commonly recommended for gradual weight loss?

• A. 250 kcal/day.
• B. 500 kcal/day.
• C. 750 kcal/day.
• D. 1000 kcal/day.

Answer: (B)

A moderate daily energy deficit supports gradual and sustainable weight loss. About 500 kcal less per day is commonly recommended because it tends to produce roughly 1 pound of fat loss per week (since 3,500 kcal roughly equals one pound). This pace is generally easier to maintain, helps with adherence, and reduces the risk of losing lean tissue or feeling deprived.

Larger deficits, like 750–1000 kcal per day, can lead to faster initial results but often make it harder to stick with the plan, potentially trim nutrient intake, and increase muscle loss or metabolic slowdown. Smaller deficits, such as 250 kcal per day, will lead to slower progress and may feel less motivating, even though they can be more sustainable for some people.

In practice, aim for enough deficit to lose about 0.5–1 kg (1–2 pounds) per week, adjust for how you feel, and pair the approach with adequate protein and resistance training to preserve lean mass while you slim down.
