Low-Carb in Perimenopause
Low-carb has loud advocates and loud critics. The truth is somewhere in between — and it depends a lot on which kind of low-carb you mean, and who you are in peri.
When low-carb helps in peri
- Insulin resistance (very common in peri)
- PCOS overlap
- Stubborn abdominal fat
- Big appetite swings driven by glucose roller-coasters
When low-carb hurts in peri
- Sleep crashes — too few carbs can wreck sleep, especially evening carbs
- Hair loss accelerates
- Cortisol rises
- Cycle disruption — for those still cycling
- Energy and mood drop
The peri-friendly middle
Most women in peri thrive somewhere around 100–150g of carbs per day — not keto-low, not high-carb. Concentrate carbs around exercise and the evening meal for sleep support. Pair with 25–35g of protein every meal.
Best low-carb foods for peri
- Lentils, beans, chickpeas
- Berries
- Greek yogurt
- Eggs
- Oily fish
- Tofu, tempeh
- Vegetables (unlimited)
- Nuts and seeds
