GLP-1 Side Effects

Muscle Loss

Loss of lean muscle mass.

Why it happens

Since we are eating fewer calories for fuel, muscle is broken down for energy along with stored-up fat reserves.

How to prevent it

Strength training and bodyweight exercises 3 times a week will help maintain muscle and prevent net loss.

How to treat it

Protein. Every time you eat, think protein first, then fiber. We are trying to reach 100 grams per day through food and supplements.

When to call a doctor

When muscle weakness is affecting your daily activities, or if you start having trouble with balance, make an appointment to see your doctor and rule out other potentially dangerous issues.
