Protein calculator
Your body needs protein to build muscle, support your metabolism, and help you recover. Whether you're aiming to lose fat, gain strength, or maintain your weight, this tool shows how much protein you need each day—based on your activity level and goal.*
Why Protein Matters After 40
As we age, particularly after 40, our bodies become less efficient at processing protein—a condition known as anabolic resistance. This means we actually need more protein to stimulate the same amount of muscle protein synthesis compared to our younger years.
Maintaining adequate protein intake is crucial for preserving lean muscle mass, supporting metabolic health, and keeping energy levels stable. When combined with a weight management journey (such as GLP-1 treatments), prioritizing protein helps ensure the weight you lose is fat, not vital muscle tissue.
Recommended protein intake
Your protein intake based on your goals
Fueling your body with enough protein helps build and protect lean muscle. It supports strength and recovery as weight changes occur. Discover treatments to support your weight loss journey.
*Protein targets are based on general guidelines from the International Society of Sports Nutrition (ISSN) and the American College of Sports Medicine (ACSM) using your weight and activity level. Your individual needs may vary based on age, muscle mass, health conditions, or dietary restrictions. This calculator does not provide medical advice.
