The daily caloric deficit should not exceed 1,000 to 1,200 kcal per day, which corresponds to a body-weight loss of about 2 lb per week.
Detail
When creating a negative caloric balance, the daily caloric deficit should not exceed 1,000 to 1,200 kcal per day. This ceiling results in a body-weight loss of approximately 2 lb per week. The deficit can be attained by decreasing caloric intake, increasing energy expenditure through exercise, or combining both — with the combination of restricted intake and exercise being recommended.
Key facts
- Daily caloric deficit ceiling: 1,000 to 1,200 kcal per day.
- Maximum recommended weight loss: ~2 lb per week.
- Compare with the 500 kcal/day deficit that yields ~1 lb/week (see adipose-tissue-rule).
Connections
- negative-caloric-balance — the deficit being limited.
- adipose-tissue-rule — the 3,500 kcal/lb arithmetic behind the rates.

3,500 kcal = 1 lb Adipose Tissue Rule
One pound of adipose tissue equals 3,500 kcal, so a 500-kcal-per-day deficit produces roughly 1 lb of fat loss in one week.Caloric Balance (Energy Balance)
Caloric balance is the relationship between the calories you take in and the calories you burn; the energy-balance equation is Caloric Intake = Caloric Expenditure.Negative Caloric Balance (Caloric Deficit)
When energy expenditure exceeds caloric intake, a caloric deficit exists and the body primarily burns stored adipose tissue, producing weight loss.
