Does this sound familiar? Your trousers are a little tighter around the waist even though you eat the same as always. Sleep is not as deep and your mood swings more often than before. Many women I see in my practice think they are doing something wrong, or that they just need to "pull themselves together".
But it is not about character. It is about biology.
Research clearly shows that metabolic changes begin long before your period actually stops. Adjusting your diet already during perimenopause is therefore not just a matter of weight — it is your most important strategy for protecting your heart, bones, and quality of life in the long run.
What Is Actually Happening in Your Body?
During perimenopause, estrogen levels decline. Estrogen is not just a sex hormone — it is a key regulator of your metabolism. When levels drop, two critical changes occur:
- Your resting metabolism drops: The body uses fewer calories at rest.
- Body composition changes: We lose muscle mass more easily and store fat instead, particularly visceral fat (fat around the abdominal organs).
This is why the diet that worked for you in your 30s may not deliver the same results now. But with the right tools you can counteract these effects.
3 Evidence-Based Nutrition Tips for Perimenopause
Here are three concrete areas where you can make a big difference, based on current research.
1. Increase Your Protein (Significantly!)
Many women eat too little protein. To counteract the muscle loss (sarcopenia) driven by aging and hormonal changes, you need more protein than before.
- Make sure every meal contains a clear protein source.
- Breakfast: Greek yogurt with seeds or scrambled eggs.
- Lunch/Dinner: A palm-sized portion of chicken, fish, tofu, or lentils.
2. Love Your Fiber (For Your Heart and Your Waistline)
Cardiovascular health becomes especially important as estrogen's protective effect diminishes. This is where fiber is your best friend.
What does the research say? High fiber intake, particularly from whole grains, has been shown in large studies to significantly lower the risk of heart disease in women. Fiber also helps stabilize blood sugar, reducing the risk of energy dips and sugar cravings.
- Swap white rice and pasta for bulgur wheat, oats, or quinoa. Add a handful of beans to your salad. Aim for at least 25–35 grams of fiber per day.
3. Don't Forget the Healthy Fats
Fat is essential for hormone production. But choose the right kind!
- Add half an avocado, a handful of walnuts, or drizzle olive oil over your salad. This contributes to satiety and heart health, in line with the Mediterranean diet principles.
