I don�t think warm drinks can have that effect because all drinks quickly equilibrate to body temperature. The larger meal, the longer it takes to be digested and absorbed. In fact, the purpose of the stomach is really to store large meals and "feed" them to the small intestine a little at a time. Hence, the small intestine is always with "fed" small meals.However, gastric emptying is often too slow (the opposite of what was said above) in upper GI disorders, so a large meal takes too long and the stomach becomes too distended. Alternatively, the stomach nerves may just be overly sensitive to distention.In that scenario, small meals should be beneficial.
