Calorie and nutrition guides: where to start and what to open next

Use this page when the question is still broad: how fat loss works, how to set a calorie target, how to log without burnout, what macros are for, and whether fasting changes anything. The point is not to read everything. It is to start in the right branch.

Guide library

The section is grouped by task so it is easier to start from the real problem instead of reading the whole archive.

Where the numbers come from and how to read them

If you want the formulas, data sources, and limitations spelled out, open the methodology page. You do not need it before you start, but it is useful once you want to pressure-test the estimates.
