Body Fat and Lean Mass

I just worked up my beginning body fat and lean pounds. Body fat start - 78.62 pounds. Lean mass start - 129.38 pounds.

Net body fat loss - 38.32 pounds.
Net lean mass loss - 14.68 pounds.
Total weight loss - 53 pounds.

I've managed to greatly slow my muscle loss by adding protein shakes, but I haven't yet completely stopped it.
