Calories in menopause: what actually changes
The myth: menopause crashes your metabolism. The reality: most of the metabolic slowdown is driven by muscle loss with age, not the hormonal transition itself. That's good news — muscle is something you can rebuild.
The numbers behind the calculator
We use the Mifflin-St Jeor equation, the most accurate widely-used BMR formula, then apply a small downward adjustment for peri- and postmenopause to reflect the documented 3–5% drop in resting metabolic rate.
Why aggressive cuts backfire
In perimenopause, large calorie deficits worsen sleep, blunt thyroid output, and amplify mood swings. A modest 15–20% deficit, paired with high protein and 2–3 strength sessions a week, almost always wins long-term.
Common reasons "calories aren't working"
- Tracking is off by 200–400 kcal/day (very common).
- Protein under 100 g/day → muscle loss → slower metabolism.
- Poor sleep raises hunger hormones.
- Years of dieting suppress NEAT (fidgeting and daily movement).
