I've heard of another benefit of avoiding snacking and only eating 2/3 meals a day - that it gives your pancreas sufficient time to recover between feeds.
Sorry, I don't have any references. I heard this from a nutritionist who recommends grain-free diets and many elements of paleo and primal nutrition. He said that digestion of a meal on average kills 50 pancreas cells. The pancreas has to work hard producing up to around 25 protein and fat digesting enzymes to digest a meal. It only produces 1 carb-digesting enzyme (that says it all!). On average it takes 6 hours for the pancreas to fully recover after a meal. Therefore one should ideally aim for at least 6 hours between meals.
The majority of people consuming SAD have compromised pancreas function due to eating patterns among other problems. Apart from diabetes, pancreatic inflammation and disease receive too little attention as there is so much focus on liver disease. Ironically, an under-performing pancreas puts more stress on the liver.
Of course, the better one's pancreas is functioning:
(a) the more optimal the absorption of nutrients and macronutrients from food
(b) the more completely proteins are broken down, which reduces the risk of immune reactions to protein fragments
