Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. I think this board over-worries about lean mass. Some lean loss is obligatory — you need less muscle to move a smaller body, and preserving mass you no longer need is not a health outcome. The question is whether strength and function held, and mine did.
Dr.NutriCornell said:I lifted three times a week throughout and still lost lean mass.
OMG yes. lean mass + resistance training is the combo. Can confirm.

Bone density monitoring on lean mass: DEXA bone density at baseline and month 12.
Lumbar spine T-score: -0.8 → -0.6 (stable to slightly improved)
Femoral neck T-score: -0.9 → -0.7 (stable)
No significant bone loss despite 50 lbs of weight loss. Key factors: adequate calcium (1200mg/day), vitamin D (5000 IU/day), resistance training 3x/week, and adequate protein. Weight-bearing exercise is critical for maintaining bone density during rapid weight loss.

What fraction of loss being lean mass is actually normal, because the numbers quoted here range from 10% to 40% and cannot all be right?
Reporting back.
Second scan under matched conditions, six months apart, same time of day: the lean number came back nearly a kilo higher than the panic scan. Strength was up throughout.
