The bypassed small intestine, which carries the bile and pancreatic enzymes that are necessary for the breakdown and absorption of protein and fat, is reconnected to the last portion of the small intestine so that they can eventually mix with the food stream.

Unlike the other procedures, there is a significant amount of small bowel that is bypassed by the food stream.
Wearing an activity tracker is one of the best ways to stay on top of your goals, as you'll literally have a ton of health information right on your wrist.

The company recently launched period tracking for their female users; there's a spot to log workouts and food and water intake; and you can challenge friends to daily or weekly competitions to keep you motivated.
