I hear this most weeks: ‘I haven’t changed what I eat. I’m gaining weight anyway, especially around my middle.’
This is one of the most common, and most misunderstood, experiences of perimenopause. It isn’t a willpower failure. It’s a metabolic shift.
As oestrogen declines, insulin sensitivity changes. Carbohydrates your metabolism handled effortlessly at 35 are now more likely to be stored, particularly around the abdomen.
At the same time, cortisol tends to run higher, and chronically elevated cortisol specifically promotes abdominal fat storage. That’s not a coincidence. It’s physiology…
What can actually moves the needle:
→ Prioritising protein - around 30g per meal, well above the amount many women consume
→ Restructuring meals around blood sugar stability rather than calorie counting
→ Addressing cortisol load, which is where sleep, stress and gut health can all play a part
This is why a generic calorie-deficit approach so often fails in perimenopause. It’s not a quantity problem it’s the hormonal environment your body is processing everything within.
Share it with someone who needs to hear that it isn’t their fault.
