Hi,

Just repeating some other thoughts. Weight loss is a major issue so stick with basic "meat and potatoes" ingredients. Fat, protein, carbohydrates. Caloric density is higher with fats and proteins so things like peanut butter, whole milk, protein powders, etc. certainly provide more to keep weight up rather than vegetables.

With a high quality blender like the Vitamix, just about anything can be blended to work with a PEG. So at least all pure and natural ingredients can be used.

Good luck
