Answer to Question 1
A nasogastric feeding tube, even though it is very small and flexible, is bothersome when left in place for extended periods of time. This could result in the patient removing it and costing additional time and money in replacing it. This is less likely with a PEG. A nasogastric feeding tube is a very small bore and would require more time and pressure for bolus feeding. The PEG is a much larger bore and is easier to work with. Because of the small bore, the nasogastric tube is more likely to clog than the PEG.

Total Calories3 balance energy intake and expenditure to maintain desirable body weight and prevent weight gain
1) The 25-35 fat recommendation allows for increased intake of unsaturated fat in place of carbohydrates in people with the metabolic syndrome or diabetes.
2) Carbohydrate should come mainly from foods rich in complex carbohydrates. These include grains (especially whole grains), fruits and vegetables.
3) Daily energy expenditure should include at least moderate physical activity (contributing about 200 kcal a day).
4) Options include adding 10-25 grams of viscous (soluble) fiber; 2 g/day of plant-derived sterols or stanols. Soy protein may be used as a replacement for some animal products.1
