TDEE for Women vs Men — How Metabolism Differs Between Sexes
6 min read May 9, 2026By TheCalcUniverse Editorial
Women and men of the same weight and height can have different TDEEs. Here is why sex differences in metabolism matter and how to adjust your calorie targets.
Why the Difference Exists
The difference is primarily body composition. Men average 10-20% more muscle mass and 10-20% less body fat than women at the same weight. Muscle is metabolically active (burns more calories at rest), while fat is less active. This means a man and woman of the same weight and age typically differ by 100-300 calories in TDEE.
Other Factors Affecting Women TDEE
Menstrual cycle: Metabolism may increase 5-10% during the luteal phase (after ovulation). Some women experience increased appetite during this phase.
Pregnancy: TDEE increases significantly, especially in the second and third trimesters. The energy cost of pregnancy totals about 80,000 calories.
Breastfeeding: Adds 300-500 calories to TDEE daily.
Menopause: Declining estrogen and progesterone are associated with decreased BMR and increased fat storage, particularly visceral fat.
What This Means For Diet Planning
Women should not compare their calorie intake to men. A 1,800-calorie diet might be a 300-calorie deficit for a woman with TDEE 2,100, while it would be a 700-calorie deficit for a man with TDEE 2,500. Use your own TDEE, not someone else is. Women should also never go below 1,200 calories per day without medical supervision.
