Multi-day hikes after WLS in Gastric Sleeve Surgery Forums Posted July 19, 2020 I live in Colorado and do a lot of hiking. Just did a 2 day backpacking trip and had no issues getting enough food and Water. I’m about 11 months post sleeve though, and can eat pretty normally (just smaller volumes). I packed cheese sticks, beef Jerky, nuts & dried fruit, Protein Bar, dehydrated backpacker meal, and oatmeal (I could handle handle 1/2 cup oatmeal around 2 -3 month mark). I definitely wasn’t as high protein/low carb as I normally am, but with the increased activity level it was warranted. I also used a Camelback for water and had a filter to refill it from the river. Hiking this summer has been so much better than the last couple of years due to my weight loss. I have a lot more energy and endurance. Enjoy! You will do great!
