Protein and strength training on Mounjaro: how to preserve muscle while losing fat

Rapid loss can include muscle loss. Learn practical protein and strength-training strategies to protect muscle, improve...

Weight loss isn’t just about the number on the scale, it’s about what you lose. Preserving muscle improves health, function, and the chance you keep the weight off.

Why muscle matters

  • Helps maintain metabolic rate and functional strength
  • Improves body composition (shape changes even if weight loss slows)
  • Supports long-term weight maintenance

Protein: a simple rule of thumb

Aim for protein at most meals. If you’re not hungry, prioritise protein and hydration first, then add produce and carbs as tolerated.

Practical protein strategies

  • Breakfast: Greek yoghurt + berries; eggs; protein smoothie
  • Lunch: lean meat/fish/tofu + salad/veg + whole grains
  • Dinner: protein + veg + fibre-rich carbs
  • Snacks: cottage cheese, edamame, tuna, protein yoghurt

Strength training (2–4 sessions/week)

You don’t need perfection: a simple full-body routine is enough. Consistency beats complexity.

If you feel weak or lightheaded

  • Check you’re eating enough protein and drinking enough fluids.
  • Don’t ‘accidentally starve’ because appetite is low.
  • Discuss dose timing and side effects with a clinician.

Bottom line

Medication can reduce appetite. Your job is to direct that smaller appetite toward nutrition that protects your body.
