I am 5 months out and this is what I eat, just about, every day:
1/2 c cream of wheat
Protein bar
3-4 oz. protein (shrimp, fish, chicken, turkey, and occasionally, red meat)
3-4 oz. protein
carrots with houmas
Greek yogurt with protein
I know my food choices sound repetitive and boring, but I really enjoy it! I guess knowing that it will get me where I want to be makes it less boring!
I'm not saying that I ALWAYS eat the right stuff. We go out of town a lot, but I try to be as good as I can...eating protein fist, ALWAYS! I even throw is a glass of wine every now and again, but not much! I also drink Water ALL DAY LONG! I even eat the ice.
I, honestly, can't imagine being able to eat the amount that you said you eat. I really wonder if he did the surgery at all...he certainly didn't do it right, that's for sure!
Also, I don't know your situation, but I cook my husband healthy food for him to take to work for lunch. This consists of a protein and 2 veggies. At night he has pita bread and houmas, 70 cal. light Dannon yogurt and a whole bag of light butter popcorn. Believe it or not, he has lost a few pounds MORE than me and we both are only 10 lbs. from our goals, and he didn't have surgery!!! Geez Louise!!! But I'm so ridiculously proud of him!!!!!!!!!
I would definitely consult a bariatric nutritionist. I would also have your general physician check to see if the operation were even done.
Good luck to you in your journey! I hope I have been a small help to you!
