Perimenopause
Weight Gain, and Your Midsection: What's Really Going On
If your jeans feel tighter even though nothing about your diet has changed, you're not imagining it — and you're definitely not alone. Somewhere between your early 40s and 50s, many women notice weight creeping on, particularly around the midsection, alongside hot flushes, disrupted sleep, and mood swings that seem to come out of nowhere. This is perimenopause: the transition leading up to menopause, and it can last anywhere from a few years to a decade.
Why the midsection specifically?
As oestrogen levels decline, your body tends to store fat around the abdomen rather than the hips and thighs. At the same time, muscle mass naturally decreases with age, which slows your metabolism — so your body needs less energy than it used to, even if your eating habits haven't changed. It's not a failure of willpower; it's biology.
The good news: small changes make a real difference
You don't need a drastic diet overhaul. A few consistent habits go a long way:
Prioritise protein at each meal — eggs, fish, chicken, tofu, legumes or yoghurt help preserve muscle as you age.
Choose low-GI carbohydrates like oats, legumes and wholegrains, which help keep blood sugar (and energy) steady rather than spiking and crashing.
Don't skip calcium-rich foods — dairy, or fortified alternatives — since bone density naturally declines during this stage too.
Move your body most days — even 20–30 minutes of walking or strength work supports mood, sleep and metabolism all at once.
What about sleep and mood?
Poor sleep and low mood are two of the most under-discussed symptoms of perimenopause, and they're deeply connected to food choices — tiredness tends to drive cravings for sugary, salty foods, which can then make sleep worse. Prioritising a consistent bedtime, along with steady blood sugar through the day, can help break that cycle.
A note on supplements and HRT
You've probably seen countless supplements promising to "balance hormones" — most, unfortunately, don't have strong evidence behind them. Magnesium is one of the more commonly asked-about options, and while research is still developing, it's generally safe to try alongside a balanced diet. Hormone replacement therapy (HRT) is a separate conversation entirely, and a genuinely valuable option for many women — but it's one to have with your GP, based on your individual symptoms and health history.
How optimising your diet can help — over time, not overnight
Nutrition isn't a quick fix for perimenopause symptoms, but done well, it's one of the most powerful tools you have. The right balance of protein, low-GI carbohydrates, calcium and healthy fats can genuinely ease symptoms like fatigue, mood swings and disrupted sleep — but what that balance looks like is different for every woman, depending on her symptoms, activity levels, health history and food preferences.
This is where working with a dietitian can make a real difference. Rather than following generic advice or the latest trending diet, you get a way of eating that's built around you — one that evolves as your symptoms and needs change through perimenopause, menopause, and beyond. Just as importantly, it's an approach that protects your relationship with food along the way, so that managing symptoms never tips into restriction, guilt, or anxiety around eating.
You don't have to navigate this alone
Perimenopause looks different for everyone, and what works for a friend might not work for you. If you're noticing changes in your weight, energy, or mood and want some clarity on what's actually helpful (rather than what's trending), that's exactly where a chat with a dietitian can help.
