I am on day 4 of my pre-op diet for VSG scheduled 3/24. For the first two days I was STARVING and snacked all day on cucumbers and bell peppers in addition to the diet plan. My diet plan consists of one protein shake for breakfast, one for lunch, and then 5 oz lean protein and unlimited non starchy vegetables for dinner. Staring yesterday and today as well I have been experiencing zero appetite. This morning I had to make myself drink the protein shake where two days ago I was savoring every sip. I am not craving any foods, not even carbs, and have little desire to eat. Is this normal? Does anyone know what is going on with me?
