There exists a diet with 3 stages. Each correlating to severity with 1 being during the most severe stages while a person can still consume orally. It basically progresses from liquids to full fluids to purees and heartier foods as tolerated. And these things are just constant longstanding rules that I've found for GP sufferers: low fibre to prevent bezoar formation, low fat so the stomach can empty more quickly, lots of liquids with nutrition and many small meals (around 6) spread approximately 2 hours apart as tolerated.
