Roux-en-Y gastric bypass (RYGB) is a type of bariatric surgery that has been used to treat for over 40 years. The procedure involves reducing the size of the stomach and bypassing part of the small intestine, resulting in a smaller stomach and reduced absorption of calories. In recent years, the procedure has become increasingly popular as a means of achieving long-term weight loss.

A recent study examined the effects of RYGB on dietary intake, physical activity, weight loss, and body composition after five years. The study included a total of 60 participants who underwent RYGB and were followed for five years. The results showed that after five years, the participants had lost an average of 28.5% of their initial body weight. Additionally, the participants had significantly reduced their caloric intake and increased their physical activity levels.

The study also found that the participants had improved their body composition after five years. Specifically, the participants had significantly reduced their percentage and increased their lean body mass. This suggests that RYGB can not only help with weight loss, but also improve body composition.

Overall, the results of this study suggest that RYGB can be an effective long-term solution. The procedure can help reduce caloric intake, increase physical activity, and improve body composition. However, it is important to note that the procedure is not without risks and should only be considered after consulting with a doctor.
