A calorie deficit is
simple arithmetic.

What is hard is doing it for sixteen weeks. So we compute the numbers exactly, tell you where they are uncertain, and pick an approach you will still be following in two months.

Calculated

Mifflin-St Jeor and Katch-McArdle. Not a lookup table.

Guarded

Hard calorie floors, and we show you every adjustment we make.

Honest

Long projections drift. We say so, and re-check every four weeks.
