Why weight gain in your 40s isn't your fault (& what actually works!)

Have you noticed that maintaining your usual weight feels harder than it used to?

You’re not imagining it—and it’s not a lack of willpower.

Research shows that weight gain during midlife is extremely common, with women gaining on average around 1.5 pounds per year during their 50s.¹ Men can experience a similar pattern of gradual weight increase² linked to hormonal changes and ageing. This phase is often referred to as “middle-aged spread” or “menopause belly”.

So, if things feel harder than they used to, there’s a real biological reason why.

What’s really going on?

As you age, three key systems begin to shift:

Hormones start to fluctuate: During perimenopause and beyond, oestrogen, progesterone, and testosterone naturally decline. This affects where your body stores fat, water retention, bloating, energy levels and appetite.
Your metabolism slows down: A gradual decline in muscle mass starts at around age 30, and since muscle burns more energy than fat, this results in burning fewer calories and your body requiring less food than before. Weight gain can happen even if nothing has changed diet-wise!³
Stress and sleep disruptions: Juggling midlife often comes with increased stress—careers, family, finances. Chronic stress increases cortisol, which encourages fat storage around the abdomen⁴ and an increase in cravings for sugar and high-calorie foods.

High stress is usually combined with poor sleep which disrupts hunger hormones (ghrelin and leptin),⁵ also leading to stronger cravings, increased overall hunger and a lower motivation to exercise.

Why old methods stop working

You might feel like you’re eating and exercising the same, but your body looks and feels different. It has different needs now. Over-restricting calories or doing intense workouts can increase cortisol, making it harder to lose fat and easier to lose muscle. This is why what worked in your 20s or 30s often stops working in your 40s and beyond.

What actually helps

Balance hormones naturally: Supporting hormonal balance is key to managing weight during this phase. Chuckling Goat’s Shatavari tincture works by rebalancing your hormones. As weight is connected to your hormones, taking Shatavari is a safe and natural way to work with symptoms such as pre- and post-menopausal weight gain.
Increase protein and fibre: Including protein and fibre in every meal will help you feel fuller for longer, stabilise blood sugar and reduce cravings. We recommend starting your day with a Gut Health Smoothie, containing Kefir, Complete Prebiotic and Pure Fish Collagen. Reducing sugar and alcohol can also make a noticeable difference.
Build strength, not just burn calories: Strength and resistance training are essential in midlife. They help rebuild muscle, boost metabolism and improve body composition. Even a couple of sessions a week can have a significant impact.
Manage stress: Try yoga, meditation, or walking in nature. Ashwagandha tincture, an adaptogenic herb, has also been shown to improve the body’s response to stress.⁶
Improve your sleep: Sleep plays a major role in weight regulation. Better sleep supports balanced hunger hormones, better food choices and higher energy levels. To help improve your bedtime routine, try reducing screen time before bed, a relaxing bath with calming, lavender soap and winding down with herbal teas.

Midlife weight gain isn’t about willpower—it’s about biology.

When you understand what’s happening and support your body accordingly, weight management becomes far more achievable—and sustainable.

If you are gaining weight rapidly or unexpectedly despite making lifestyle changes, it’s worth consulting a healthcare professional to rule out conditions such as hypothyroidism.
