High-Fat Pre-Run Gastric Emptying
High-fat pre-run gastric emptying delays stomach clearance—heavy fatty meals before hard runs invite nausea and reflux once pace picks up.
High-fat pre-run gastric emptying slows when bacon, cheese, or fried meals sit in the stomach—nausea and reflux rise once pace increases before the gut clears. Fat is not evil daily, but race morning and the prior dinner often need lower fat for sensitive runners.
Allow four or more hours after heavy meals before hard sessions.
Common questions
-
Are eggs and avocado too fatty before a run?
Depends on portion and timing—many tolerate modest fat four hours out. Problem meals are large fried or cheesy dinners twelve hours or less before key workouts.
