Calories for the Mission: BMR & TDEE for Service Members

Why knowing your BMR and TDEE matters for ABCP weight loss, ACFT fueling, and staying strong through a body-composition program.

Educational reference only. The numbers on this page summarize public service regulations for planning purposes. They are not official medical, recruiting, or administrative determinations. Always confirm your status with a recruiter, commanding officer, or hiring agency using the official assessment.

The two numbers

BMR is your resting burn (Mifflin–St Jeor is the most accurate formula). TDEE multiplies BMR by an activity factor — for military training, often 1.6–1.9. TDEE is the number to plan around.

ABCP math

The Army standard is 3–8 lbs per month. A pound is roughly 3,500 kcal, so that is a 350–900 kcal daily deficit. Too steep a deficit costs muscle and ACFT performance; 300–500 kcal below TDEE with 1.6–2.2 g/kg protein hits the target sustainably.

Fueling the test

Before a record ACFT or CPAT, eat to performance — a 200–300 kcal pre-test meal and normal hydration. Never fast into a weigh-in-plus-test day; it erodes both results.

Calculate your TDEE

Total daily energy expenditure by activity level — what to eat to sustain a training cycle.

Result

BMR1808 kcal/day
TDEE2802 kcal/day

Quick answers

Will losing weight hurt my ACFT score?
Losing fat at a moderate deficit while strength training usually preserves or improves run times; crash dieting costs strength and power. The 540 exemption exists precisely so strong, lean-muscled soldiers are not penalized by the tape.
