Appetite crashed on tirz week 2. Hitting 80-90g protein daily when my maintenance target is 140+. Is this acceptable for a 12-week cut or am I eating into lean mass?

80-90g at maintenance target of 140+ is under-eating protein by 35%+. You will lose lean mass on this pattern over 12 weeks. Force it up. Whey shakes 2-3x daily are the easy fix.

Prelog the day. Breakfast shake (35g) + lunch shake (35g) + meat at dinner gets you to 110 without effort. Then supplement.

Liquid protein is your friend. Whey isolate + water hits easier than meat on tirz. Adjust dose down if you can't hit target.

Under-protein + GLP-1 + deficit is the lean mass trio that tanks DEXA results. Fix protein first or cut dose.
