Daily calorie scenario
1,870 kcal
112 g protein · 239 g carbs · 52 g fat. Customize this split in the macro calculator.
Illustrative time range at a constant pace
13.3–20.8 weeks
Central scenario: 0.30 kg/week. This arithmetic does not model metabolic adaptation.
Inputs stay in this tab. Saving keeps a copy on this device until you reset or clear it.
For adults outside pregnancy, breastfeeding, and eating-disorder recovery. Calorie and training needs are individual. Fixed calorie differences do not produce constant weight change in real life.
How this tool works
Use a formula-based or observed maintenance estimate. The selected percentage produces a deficit for a lower goal weight or a surplus for a higher one. Macro starting points follow the same method as the macro calculator.
The timeline is a constant-pace illustration: daily calorie difference × 7 ÷ 7,700 gives a nominal weekly weight change. The time range is 80% to 125% of the central estimate, chosen to illustrate sensitivity, not a confidence interval. Real weight change is nonlinear. This tool does not implement or claim equivalence to NIDDK's dynamic model.
Dates compare your desired schedule with the illustration; they do not force a larger deficit. The tool does not generate weight-loss goals below BMI 18.5 or calorie scenarios below 1,200 kcal/day. These display limits are not a guarantee of nutritional adequacy.

Frequently asked questions
Will I reach the goal on the shown date?
The date illustrates a constant pace. Changes in energy needs, water, activity, and adherence can move the real timeline. Reassess with several weeks of data.
What do I do with the calorie result?
Use it in the macro calculator, customize the split, then send the targets to Remaining Macros. Review the plan with the Progress Calibrator.
