Personally, I think the caloric intake is too high. I had my surgery on 7/14/16. Stage 3 -- days 3-14 after surgery -- I was only allowed 1-2 oz o f mushy, soft, high Protein food (no red meat). Stage 4 -- days 15-30 after surgery-- I'm eating 2-3 oz regular textured high protein meals and I can add 1-2 Tblspoons of soft canned fruits in Water or bananas and/or 1/2 high Fiber cereals. In Stage 5 -- at 1 month -- I can eat 3-4 oz regular textured high protein meals and red meat is allowed plus lettuce w/low cal dressing or soft non-starchy vegetables. Throughout these stages, I'm must include 40 total grams per day by drink protein.
The drink protein is usually between 160-210 calories. But since I'm in Stage 4, I'm only getting 300-400 calories with regular food, plus the drink protein. I'm one of those people losing about a pound a day.
And to be honest, I'm looking at the future stages, and I don't see that I'll really ever get much above 800 calories. I'm pretty happy as I feel good and energetic, especially when I make sure I'm getting 7-8 hours of sleep.
I do track my food intake and I weigh everything so far, and I eat 3 meals per day (no Snacks at this point). The only exercise I'm doing at this point is walking about 30 minutes per day. But I will start swimming as soon as the rain stops.
Everyone that worked with me has made it clear that this sleeve is a tool, not magic. If I were you, I'd talk to your nutritionist again and talk about the caloric intake.
