After surgery, your body runs a construction project 24 hours a day. What you eat is the supply line.
Tissue repair increases both energy and protein needs — often meaningfully. Under-eating after surgery, whether from appetite loss or fear of inactivity weight gain, slows healing and accelerates muscle loss in the limb you're trying to protect. Eat to heal first; body-composition goals come later. As with everything on this page, these are evidence-based considerations to discuss with your care team — not one-size-fits-all instructions.
Colorful produce, omega-3-rich fish, nuts, olive oil, and whole grains support the healing environment; heavily processed food and excess sugar work against it. Vitamin C intake supports collagen formation, and early research suggests collagen supplementation with vitamin C around rehab sessions may support tendon and ligament healing3 — an emerging area, and a reasonable topic to raise with your care team rather than something to start on your own.
Supplement decisions — protein powders included — are best made together with your primary care physician and surgical team, and in select cases laboratory testing may be appropriate to guide them. For patients interested in a structured option, the Thrive Protocol is a physician-developed perioperative nutrition system worth raising in that conversation.
This page is general education, not medical advice or an individualized plan. Nutritional needs and training progressions vary — always follow the specific guidance of your surgeon, physician, physical therapist, or dietitian, and do not start, stop, or change any supplement, medication, or diet based on this page without discussing it with your primary care physician and surgical team first.
