How much weight can be safely cut?

A safe, conservative cut is 2-3% of body weight (water loss) over 24-48 hours. Cuts exceeding 5% significantly impair performance even after recovery time. Cuts above 7-8% carry serious health risks.

What is the safest weight cut method?

Gradual water restriction and low-sodium diet over 24-48 hours (with no food in the final 12 hours) is safer than sauna or rubber suit methods that can cause rapid electrolyte imbalances and heat illness.

How long before competition should the cut start?

Ideally, athletes should compete within 2-3% of their walking weight to avoid health risks. If a cut is needed, it should be completed with sufficient rehydration time (at least 2-24 hours) before competition.
