A good friend of mine had a Sleeve gastrectomy:
He was 320lbs/6'2 (150kg/1.85m), and thankfully was still of relatively good health (no known deseases or anything off-charts) since he's only 22 years old and moves around a lot (and is genetically well-built besides having had the cravings).
Now past the surgery he's dropping 2kg/4.4lbs a week on average. He's already at 281lbs/128kg.
Guy's "problem" is that he can't pack in food. He's only now (four weeks past surgery) beginning to eat normal foods again (could only digest soups and such prior to that), and is having trouble eating more than say 200 grams of food in one meal.
He wants to start training so he could look better. I really don't know if that's wise, considering he can barely maintain sufficient nutrients to keep going throughout the day.
Have you guys had any experience with people in that situation?
Can such a man ever train hard, or train seriously at all?
If so - what kind of training and nutrition will best suit his condition?
