In this BoardsCast episode, we begin Tobias Chapter 98 by dismantling the most expensive mistake in postoperative care:

The surgery went perfectly… and the patient still declined.

That outcome usually isn’t hardware failure or incision failure. It’s a metabolic failure because malnutrition drives surgical failure, even when the operation succeeds. 

This episode rebuilds your mental model around one dominant truth:

Nutrition is active metabolic treatment — not “supportive care.”

You’ll learn:

• Why trauma/illness forces the body into a catabolic state (energy demand spikes while intake drops) 
• Why the body burns lean muscle first — and how that directly impairs immunity and wound healing 
• The fork in the road:
  • Scenario A: proactive feeding → preserved protein balance → healing
  • Scenario B: delayed feeding → protein catabolism → infection + failure
• The predictable clinical errors: “wait one more day,” treating feeding tubes like a last resort, and tunnel-vision on the incision while weight/muscle drops 
• The golden doctrine: If the gut works, use it — enteral feeding protects the mucosal barrier and reduces bacterial translocation 
• Why enteral beats TPN: safer, more physiologic, lower infection risk, lower cost 
• The danger of doing it wrong: Refeeding syndrome (electrolytes shift into cells after insulin surge) and why you start at ~50% RER and ramp over 3–4 days 

This episode gives you the rule that changes outcomes:

The surgery fixes anatomy. Healing is metabolic.
