This guide sets out what the evidence supports, what to eat in the weeks before surgery, what to avoid, and how to handle the fasting period on the day itself.

The goal of pre-operative nutrition is not to lose weight, body composition, or chase any metric. It is to arrive at with adequate stores of the nutrients your body will need to repair itself.

What to focus on in the 4 to 6 weeks before surgery

Protein is the for almost the body does during wound — collagen synthesis, immune function, replacement of blood proteins, new tissue formation. protein intake is the most nutritional variable, and the one most underestimated.
