Getting enough protein is the single most important nutritional goal after bariatric surgery. This calculator gives you a personalised daily target based on your surgery type, height, and activity level -- using your ideal body weight so the result is clinically grounded without asking you to enter your current weight.
Protein targets are based on published bariatric nutritional guidelines (ASMBS 2020 and IFSO 2023), using ideal body weight calculated via the Devine formula. Individual needs vary based on your specific surgery, any complications, current health status, and advice from your bariatric dietitian. Always confirm your personal protein target with your clinical team.
