The math

A pound is roughly 3,500 kcal, so 3–8 lbs/month is about a 350–900 kcal daily deficit. A 300–500 kcal deficit with 1.6–2.2 g/kg protein preserves muscle and ACFT performance better than crash dieting.

Train through it

Keep strength work (deadlift, carries) and run conditioning; the 540 ACFT exemption exists so strong, lean soldiers are not penalized by the tape. Losing fat at a moderate deficit while lifting is the durable path.

Quick answers

Will cutting weight hurt my ACFT?
Crash dieting costs strength and run speed. A moderate deficit with adequate protein and continued lifting usually preserves or improves the test — which is exactly why the 540 exemption protects lean, strong soldiers.
