Can this calculator replace a body fat scan or professional assessment?

No, the Omni Calculator provides an estimate based on standard formulas using weight, height, age, and gender. It cannot replace clinical body composition analysis or professional medical evaluation.

Why do muscular people sometimes weigh more than others with higher body fat?

Lean body mass includes muscles, bones, organs, and other non-fat tissues. Two people at the same total weight can have very different lean mass amounts, which is why muscle density affects appearance and scale readings differently than fat.

Does the calculator require exact measurements or can I use approximate values?

You can enter your current weight and height as you know them; the tool will process those inputs using its formula. For best results, use your most recent and accurate measurements.

Can I use this calculator to determine how much fat I should lose?

The calculator helps you monitor lean mass during weight loss, which can indicate whether you are losing muscle or fat. It is designed to support fitness tracking, not to prescribe specific fat loss targets.
