When you lose weight, you want to lose fat, not muscle. Muscle keeps your metabolism up, your body strong and your results easier to maintain. The good news: a few simple habits protect it.
Why muscle loss happens
When you eat fewer calories, your body can use muscle as a fuel source along with fat, especially if protein is low, weight is lost very quickly, or you are not using your muscles.
1. Eat enough protein
Many people losing weight aim for about 1.2 to 1.6 g of protein per kilogram of body weight per day, spread across meals (roughly 25 to 35 g per meal). Use our protein calculator to estimate your target and check with your doctor if you have kidney disease.
2. Strength-train two to three times a week
Weights, resistance bands or bodyweight exercises give your muscles a reason to stay. Sessions can be short. Start light and build gradually, and ask your doctor if you have any limitations.
3. Do not cut calories too aggressively
Very steep deficits increase the risk of losing muscle and make the plan hard to sustain. A steady pace is usually better. Our weight-loss forecast helps you set a realistic one.
4. Sleep and manage stress
Poor sleep and chronic stress make it harder to keep muscle and easier to crave sweets.
5. Keep moving
Daily walking supports your heart, mood and energy, and complements strength training.
Protein foods and products that help
Eggs, fish, poultry, lean meat, Greek yogurt, cottage cheese, tofu and legumes should be your base. Our protein shakes and bars can fill the gaps. If you use a GLP-1 medication, see our GLP-1 nutrition guide.
