How Many Calories Does a 30-Year-Old 150 lb Woman Need?

Using the Mifflin-St Jeor equation with your exact inputs — age 30, weight 150 lbs (68.0 kg), average woman's height (162.6 cm) — the resting metabolic rate is 1386 kcal/day. With typical daily activity, total calorie expenditure (TDEE) ranges from 1663 kcal (sedentary) to 2390 kcal (very active).

Age 30 note: Late twenties — metabolism is still strong. Prioritize protein and resistance training now to build a metabolic foundation that serves you for decades.

✅ Maintenance	1905 kcal	Weight stable
💪 Lean bulk	2205 kcal	~0.5 lbs/week
🏋️ Aggressive bulk	2405 kcal	~1 lb/week

Calorie Needs by Activity Level

Activity Level	Description	Daily Calories
Sedentary	Desk job, minimal movement	1663 kcal
Lightly active	1–3 workouts/week	1905 kcal
Moderately active	3–5 workouts/week	2148 kcal
Very active	Hard training 6–7 days/week	2390 kcal

BMI at 150 lbs

At 150 lbs (68.0 kg) and average height for a woman (162.6 cm), your BMI is 25.7 — Overweight ⚠️. BMI is a useful screening tool but doesn't measure body composition. Waist circumference and muscle mass provide additional context.

Macronutrient Split at 1905 kcal

Macro	% of Calories	Grams/day	Calories
Protein	30%	143 g	572 kcal
Carbohydrates	40%	190 g	760 kcal
Fat	30%	64 g	576 kcal

For weight loss at 1405 kcal/day, increase protein to 35% (123 g/day) to preserve muscle during the deficit. At age 30, protein becomes increasingly important for maintaining metabolic rate.
