Weight for divers with higher body fat: what to know
Body fat is less dense than muscle, so a higher-fat build floats higher and takes about 1 kg more lead in this model. Keep it as a starting guess and confirm with a buoyancy check.
Worked example
For an 80 kg diver with higher body fat, wearing a 5 mm wetsuit and using an aluminum 80 tank in saltwater, the calculator estimates 7.5 kg (16.5 lb). Your number will differ with your body and gear, so enter your own values above and then do a buoyancy check.
Common questions
Do divers with more body fat need more weight?
Often a little. This model adds about 1 kg.
Why does fat float?
Fat is less dense than water and muscle, so it adds lift.
Is this setting about fitness?
No. It only describes body composition for the estimate.
Should I add weight beyond the estimate?
Only if a buoyancy check shows you need it, and in small steps.
Do other factors matter more?
Yes. Suit, tank and water change the answer more than build.
