GLP-1 medications such as Ozempic or Wegovy are effective for weight loss, but they carry a risk that many people underestimate: muscle loss. Research shows that some of the weight lost during GLP-1 use consists of muscle mass rather than just fat. Good news: you can actively counteract this. In this blog, you'll learn exactly how, with practical nutrition and training tips.
Why do you lose muscle mass while using GLP-1?
When you eat significantly less, you create a caloric deficit. Your body then has less fuel and starts looking for alternative energy sources. In addition to fat, it also breaks down muscle tissue for energy, a process that accelerates the greater the caloric deficit. Because GLP-1 medication significantly reduces your appetite, you sometimes eat much less than you realize, resulting in muscle breakdown.
Tip 1: Eat enough protein, even if you're not hungry
Proteins are the building blocks of your muscles. If you eat enough protein, you give your body the building blocks to repair and maintain muscles, even when you're eating fewer calories.
Guideline: aim for at least 1.6 grams of protein per kilogram of body weight per day. For a weight of 70 kilograms, that's about 110 grams of protein.
The challenge with GLP-1 use: you hardly feel hungry and large meals are difficult to eat. Therefore, opt for small, protein-rich options that are easy to digest:
- Quark or Greek yogurt
- Eggs
- Chicken breast or tuna
- A compact, protein-rich meal shake
The Killerbody Meal Shakes are ideal for this. They are specially developed as complete meal replacements with a high protein content and a full amino acid profile. Compact, quick to prepare, and easy to digest. Exactly what you need when you have little appetite but still want to give your muscles the right nutrition.
Tip 2: Do strength training, even when losing weight
Strength training is the most powerful signal you can give your body to preserve muscle mass. When you train, you give your body a reason to spare muscles, even with a caloric deficit.
You don't have to become a heavy powerlifter. 2 to 3 short sessions a week with targeted exercises are enough to make a difference.
Effective exercises for home or the gym
Legs and glutes:
- Squats: 3 sets of 12 repetitions. Feet shoulder-width apart, knees behind toes.
- Lunges: 3 sets of 10 per leg. Good for balance and strength.
- Glute bridges: 3 sets of 15. Lie on your back, feet on the ground, lift your hips.
Back and arms:
- Rows with resistance band or dumbbells: 3 sets of 12. Pull your elbows back.
- Deadlift with light weight: 3 sets of 10. Good for the entire backside of your body.
- Bicep curls: 3 sets of 12. Keep your elbows close to your body.
Core and stability:
- Plank: 3 times 30 to 45 seconds. Keep your body straight like a plank.
- Dead bug: 3 sets of 10 per side. Excellent for deep abdominal muscles.
Start light and build up gradually. Consistency is more important than intensity, especially when you're just starting.
Tip 3: Combine exercise with sufficient recovery
Muscles don't grow during training, but during rest. Ensure sufficient sleep (7 to 9 hours) and give your body time to recover between training sessions. Overtraining actually leads to more muscle breakdown.
Tip 4: Drink enough water
GLP-1 medication can also reduce thirst. But drinking enough water is essential for muscle function, metabolism, and recovery. Aim for at least 1.5 to 2 liters of water per day.
