 Formula referencing a simplified method to estimate ideal daily calorie needs for moderate activity:

Formula:

(0.45 × body weight in lbs) + 25–50% of that result

This assumes:

0.45 × weight estimates basal energy needs

Adding 25–50% covers energy for moderate activity

---

Example (for a 160 lb person):

1. 0.45 × 160 = 72 calories (base per hour)

2. Multiply by 24 hours:

72 × 24 = 1,728 calories (baseline)

3. Add 25–50% for activity:

25%: 1,728 + 432 = 2,160 calories/day

50%: 1,728 + 864 = 2,592 calories/day

Estimated calorie needs = 2,160–2,592 kcal/day for moderate activity
