Gaining Weight after Surgery

I had RNY surgery 28 months ago. Some individuals have surgery and gain some or all of their weight back. I wanted to know why. My nutritionist said this was caused by "grazing" - eating Snacks throughout the day in place of full meals.

I ran across some research that seems to back up this hypothesis.

The researchers, publishing in Cell Metabolism, created a free app and asked volunteers (from the general population) to snap a photo of everything they ate. The app then records the photo, with a time and date stamp, and sends the data to researchers. The study’s overall goal was to look at the time span between the first meal of the day and final meal, to learn about people’s eating habits.

The results showed that the majority eat over a 15-hour period each day. Some research suggests that limiting the “eating window” to 10-12 hours per day may contribute to weight loss. Their sample size was small, but of their volunteers interested in weight loss researchers set the app to help them restrict food intake to a 10-hour window. Without changing the types of food they were eating over 13 weeks, this volunteer group lost an average of 3.5 percent of their initial weight per person.
