UNDERSTAND THE METHOD

How to use this calculator

Supply a current intake and a higher maintenance estimate. Select a weekly increase. The final week stops at the maintenance value. This is a schedule based on your assumptions.

What the result can tell you

The schedule and comparison score are product heuristics. Research does not validate this exact sequence or prove that a gradual ramp prevents fat gain. Actual maintenance can differ from the supplied value.

Common questions

How does the weekly calorie ramp work?

Enter current intake and a higher supplied maintenance estimate. Select a weekly increase. The calculator estimates the number of weeks and stops the final week at the supplied maintenance value.

Does a gradual ramp prevent fat gain?

No. The schedule is a product heuristic based on your assumptions. Research does not validate this exact sequence, and actual maintenance can differ from the supplied value.
