(And What You Can Do About It)
If you're a woman over 40 living in or near Birmingham, and you're wondering:
“Why is my belly changing when I haven’t changed anything?”
You’re not alone — and you’re not going mad. In fact, if you’re in perimenopause or postmenopause, there’s a clear physiological reason behind the shift in how and where your body stores fat.
As personal trainers and nutritionists in Birmingham, we work with dozens of women going through the same thing — and the science backs it up.
Let’s dive in.
What the Research Says About Menopause and Belly Fat
🧬 Study 1 – Lovejoy et al., 2006
“Women who didn’t use hormone therapy saw a 40% increase in deep belly fat in just 2 years.”➡️ PubMed link
This study focused on women in early postmenopause. Even without gaining weight, they experienced a significant increase in visceral fat — the deep belly fat that surrounds your organs and increases health risks.
And guess what? That shift wasn’t caused by overeating or laziness — it was caused by declining oestrogen.
⚠️ Study 2 – Sims et al., 2012
“This isn’t about calories. It’s about your body adapting to hormonal decline.”➡️ PubMed link
That quote says it all.
During menopause, your body becomes more insulin-resistant, your metabolism changes, and your fat storage shifts to the abdomen. So even if you’re eating well and exercising, your body might not respond the way it used to — unless your plan adapts.
Here’s What’s Happening Inside Your Body
↓ Oestrogen → ↑ Visceral Fat → ↑ Insulin Resistance → ↑ Belly Fat
You don’t need to be a biochemist to understand what’s going on.But you do need a nutritionist or coach who understands how this affects your results.
That’s why so many women I work with in Birmingham come to me saying:
“I feel like I’m doing everything right… but nothing’s working anymore.”
And that’s exactly what we fix.
Here’s What Actually Works for Women Over 40
✅ 1. Strength Training for Menopause in Birmingham
Strength training is one of the most powerful tools to:
Improve insulin sensitivity
Rebuild lean muscle mass
Boost your metabolism
Reduce belly fat
As personal trainers in Birmingham who specialises in training women over 40, we can confidently say: You don’t need to be “fit” to start. You just need the right plan and support.
✅ 2. Higher Protein Nutrition Coaching
Most women over 40 are under-eating protein, which leads to:
Slower recovery
Muscle loss
Poor energy and cravings
In our nutrition coaching programme in Birmingham, we focus on building meals that support muscle, energy, and satiety — without calorie obsession or fad diets.
✅ 3. Real Meals — Not Restrictive Diets
Starving yourself is not the answer. You need a plan that includes:
Protein
Colourful veg
Balanced carbs and healthy fats
This supports your metabolism and hormones, reduces cravings, and actually works in the real world (even with kids, work, and stress).
