Use the slower deficit if you're in perimenopause, aggressive cuts often backfire with sleep, mood, and cycle disruption.

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).

Calories are step one. Lila handles the rest.
