How Long to Reach a Target Weight (Calorie Deficit)
Estimate weeks and months to go from current to target weight using a daily calorie deficit and the rule of about 7,700 kcal per kg of fat. Supports kg or lb input; results round weeks and show approximate months.
How to use
Pick kg or lb, enter Current weight, Target weight, and Daily deficit (kcal). Read estimated weeks and months. If target is already reached, you see a reached message.
Example
85 kg to 75 kg with 500 kcal/day deficit: about 10 kg to lose, roughly 77,000 kcal total, near 154 days or about 22 weeks.
Tips
Real loss varies with water, muscle, and adherence. Very large deficits are not recommended without professional supervision.
