Advanced Macro Calculator for Women

Women's bodies have unique nutritional needs due to hormonal fluctuations throughout the menstrual cycle, pregnancy, breastfeeding, and menopause. Our calculator accounts for these physiological differences, adjusting protein, carb, and fat ratios based on your current life stage and health conditions like PCOS or thyroid issues.

During the follicular phase (days 1-14), your body handles carbohydrates better and may need slightly fewer calories. In the luteal phase (days 15-28), progesterone increases, raising your metabolic rate by 100-300 calories daily. Our calculator automatically adjusts your macros based on your reported cycle phase.

Women with PCOS often benefit from a lower carbohydrate approach - typically 35-40% carbs, 30% protein, and 30-35% fat. This helps manage insulin resistance. Our calculator automatically adjusts to these ratios when you select PCOS, while ensuring adequate fiber intake for hormonal balance.

Yes! During pregnancy (2nd/3rd trimester), you need an additional 300-500 calories daily with increased protein, folate, and omega-3s. Breastfeeding requires about 500 extra calories plus significantly more water (3-4L daily). Our calculator makes these adjustments automatically based on your selection.

Our calculator uses the Mifflin-St Jeor equation, which is considered the most accurate for women, with a typical accuracy of ±10%. We then apply evidence-based adjustments for hormonal phases, health conditions, and activity levels. Remember, these are starting points - monitor your progress and adjust as needed.

Absolutely! Menopause brings metabolic changes that our calculator accounts for. We recommend higher protein intake (1.2-1.6g/kg body weight) to preserve muscle mass as estrogen declines, plus adjustments for bone health nutrients. The calculator provides specific recommendations for this life stage.
