Losing Weight on GLP-1 During Menopause: What You Need to Know

With expert insights from Kate Di Prima, Dietitian

Menopause already changes the rules around weight and metabolism. Add a GLP-1 medication into the mix, and it can feel like you're navigating two sets of changes at once. Here's what's actually going on and what helps, drawing on guidance from dietitian Kate Di Prima.

Why Menopause Changes the Equation

During menopause, declining oestrogen naturally accelerates the loss of muscle mass, a condition known as sarcopenia. It's possible to lose up to 8% of muscle mass per decade from your 40s onward, and this can increase after menopause. Muscle isn't just about how you look, it supports strength, metabolism, connective tissue, bone health and balance.

GLP-1 medications work by slowing stomach emptying, reducing appetite and helping you feel fuller for longer, which is exactly why they've helped many women finally see the scale move after years of frustration. But the same appetite reduction that supports weight loss can also mean your protein intake quietly drops. As dietitian Kate Di Prima's guidance points out, your muscles don't get the memo that you're trying to lose fat, they simply respond to not receiving enough building blocks, regardless of your goals.

Put together, menopause and GLP-1 medication create a combined effect worth actively managing: hormonal muscle loss on one side, and reduced protein intake on the other.

Three Fundamentals That Help

Prioritise protein at every meal

Most menopausal women taking a GLP-1 medication benefit from aiming for around 25 to 30 grams of quality protein per meal. Good options include Greek yoghurt, eggs, lean chicken, meat, fish, tofu, legumes and high-protein dairy foods.

Spreading protein intake across the day, rather than concentrating it at dinner, supports muscle maintenance more effectively.

Make resistance training non-negotiable

Lifting weights, using resistance bands or performing bodyweight exercises signals to your body that muscle is still needed. Two to three sessions a week can make a real difference, without needing to spend hours in the gym.

Resistance training during menopause also supports insulin sensitivity, resting metabolic rate and bone health, alongside its role in preserving muscle.

Balance your blood sugar

Blood sugar swings become more common during perimenopause and menopause due to hormonal shifts, and when blood sugar crashes, hunger, energy and cravings can all be affected. Combining protein, fibre and healthy fats in meals, rather than eating carbohydrates on their own, helps keep blood sugar steadier. Eating regularly, even on busy days, matters here too, rather than skipping meals in an attempt to eat less overall.

Focus on Nutrient Density, Not Just Volume

When you're eating less overall, and menopause is already changing your nutritional needs, every mouthful needs to count. Your body still requires adequate vitamins, minerals and protein to support healthy muscles, bones and general wellbeing, regardless of how much less you're eating.

Where Glow Shakes Can Fit In

For women struggling with reduced appetite, sipping a shake is often far more achievable than preparing and eating a full meal, especially in the early stages of GLP-1 treatment. The Collagen Co Glow Shakes provide 29g of protein per serve along with important vitamins and minerals, in a format that's easy to consume even when you don't feel particularly hungry.

While no single product replaces a healthy diet, Glow Shakes can help bridge nutritional gaps by supporting protein intake and improving overall nutrient quality when food intake is reduced. They can work well as a breakfast, lunch or post-exercise option.

The goal isn't simply to become lighter, it's to become healthier, stronger and more resilient. Weight loss should never come at the expense of muscle, and this is especially true during menopause.

Key Takeaways

• Menopause and GLP-1 medication can compound muscle loss risk, one through hormonal change, the other through reduced food intake.

• Aim for 25 to 30g of protein per meal, spread across the day.

• Resistance training two to three times a week helps protect muscle and supports bone health.

• Balancing blood sugar through protein, fibre and healthy fats can ease cravings and energy dips.

• A shake like Glow Shakes can help on days when a full meal feels out of reach.
