I don't see how reducing body-fat percentage will ever help much when chasing an absolute number. It will help in reaching relative numbers like 2.5 bw deâdlift, and not being an unhealthy non-athletic fatass, which are good enough reasons alone, but let's not pretend that 500 lbs deadlift would be easier if he suddenly had a liposuction. Though deadlift specifically is said to be the lift that drops the least from losing weight.
