Bariatric Athlete Protein Calculator
Get a personalized daily protein target designed for your surgery type, training goals, and stomach capacity.
Protein is the most critical nutrient for anyone who has had bariatric surgery or is taking a GLP-1 medication like Ozempic, Wegovy, or Mounjaro. Without adequate protein, rapid weight loss from these interventions can cause significant muscle loss — research shows 25–40% of weight lost can be lean mass without proper protein intake and resistance training.
This calculator gives you a personalized daily protein target based on your surgery type, current and goal weight, months post-op or on medication, athletic goals, and training frequency. It accounts for the unique protein absorption differences of gastric bypass and duodenal switch patients, the appetite suppression challenges of GLP-1 medications, and the increased needs of active athletes.
How to use this calculator: Select your surgery or medication type, enter your current and goal weight, tell us how long you've been post-op or on your GLP-1, choose your athletic goal and training frequency, then click Calculate. You'll get a daily protein target, a per-meal breakdown, a sample meal plan, and personalized tips.
