For the most part, depending upon how much of your small intestine is bypassed, you can enjoy some malabsoprtion for the first 6-12 months (after that, our bodies tend to compensate so malabsorption essentially stops). Some studies suggest that, during this brief period, we only absorb about 80% of the total calories. But, because the malabsorption is short-lived, many of us are taught to not rely upon it but to, instead, try to learn healthier long-term eating habits.

Steve nailed it. I was surprised to find out that our bodies learn to absorb all the calories over a period of time, but this would account for the "honeymoon" phase and the slowing of weight loss later on. Also accounts for the ability to gain back weight easily later as well. Keep it in mind and plan for it. Many folks get complacent and don't realize how easy it is to get off track and gain weight back. Weight gain after surgery is common, so you need to figure out what works for you in keeping you on track early on and use those techniques from there on out. For me, I work to keep my pouch as small as I can by not overeating. Do what you can to recognize that full feeling early on (which can be hard right after surgery since the stomach is numb for many) and stop. If you are throwing up often due to the amount you eat (and not because something is stuck or you have a stricture in your stoma) then you are eating too much and risk stretching the pouch out. The good news is that although you will naturally be able to eat more as time goes on (swelling in the pouch goes down and capacity increases along with relaxing of stomach muscles), you can shrink it back by going very light on food for a few days. Using this "tool" to work with you is what it's all about! Good luck! Dina

Which type of bypass? I am radically distal, so I figure I absorb 5-10% of fats & oils, therefore all fat soluble vitamins. I absorb MORE THAN 100% of any sugar that comes near me. Since it begins absorbing in the mouth, and I'm more prone to gain with it, I'm serious about 100% or more! What IS malabsorbed: protein, iron, calcium, A, D, E, zinc, B12, B1, SOME fats/oils, some complex carbs. How much? I figure about 30-50% for proximals. I've never counted calories, only sugar g and protein supplement g.
