What to Eat on Ozempic, Wegovy, or Mounjaro: Protecting Muscle on a GLP-1

GLP-1 medications like Ozempic, Wegovy, and Mounjaro are changing how many women approach weight management. One of the most common — and least talked about — challenges for women using them is not the appetite suppression itself, but figuring out what and how to eat when you are rarely hungry. Getting this right matters far more than most people realise.

Why Nutrition Matters More, Not Less, on a GLP-1

When you eat significantly less, your body does not automatically burn fat. Without the right nutritional approach, a meaningful portion of the weight lost on a GLP-1 can come from muscle — not just fat. This is called muscle wasting, and it is a real concern for women on reduced-calorie intakes, especially those over 40 who are already working against age-related muscle loss.

Protecting muscle matters not just for how you look and feel. Lean mass supports your metabolism, bone density, energy, and long-term physical independence. Losing it now makes maintenance much harder later.

The Most Important Nutrient: Protein

If there is one nutritional priority for women on GLP-1 medication, it is protein. When overall calories fall, a higher proportion of what you eat needs to come from protein — to signal muscle preservation and keep you satiated longer between meals.

A practical target is at least 1.2–1.5 grams of protein per kilogram of bodyweight per day, prioritised at every small meal, even on days when appetite is very low. Easy high-protein foods that are well-tolerated on GLP-1s include:

• Greek yoghurt and cottage cheese
• Eggs and egg whites
• Tinned fish (salmon, sardines, tuna)
• Edamame, lentils, and chickpeas
• Chicken, turkey, and lean mince
• A high-quality protein shake blended into a smoothie on low-appetite days

Eating When You Are Not Hungry

One of the real challenges of GLP-1 medications is that appetite suppression makes it easy to under-eat to the point that nutrition suffers. Rather than waiting for hunger signals, eating by the clock — small, nutrient-dense meals every 3–4 hours — helps protect both energy and muscle. On difficult days, treat eating as maintenance work rather than enjoyment.

On high-nausea days, cold and bland foods are often better tolerated than hot or rich ones. Plain Greek yoghurt, a protein shake, or oats with protein powder can cover nutritional needs without triggering nausea.

What to Focus On (and What to Ignore)

You do not need to count every calorie. Focus on:

• Hitting a protein target at each meal, even a small one
• Drinking enough water throughout the day — dehydration is common on GLP-1s
• Including vegetables and fibre when appetite allows
• Taking a good multivitamin to fill gaps caused by reduced food volume
