Question 1

How do I know body fat %?

Accepted Answer

Use calipers, BIA scales, Bod Pod, or DEXA. Methods differ — stay consistent.

Question 2

Is LBM the same as muscle?

Accepted Answer

LBM includes muscle, organs, bone, and water — not pure skeletal muscle.

Question 3

Athletic formulas?

Accepted Answer

Boer/James formulas estimate LBM from height/weight without BF%; this tool uses BF% directly.
