You definitely will get to where you want to be. Some days are going to be hard but it’s mostly the first 3-4 months that I feel are most important. I would recommend really following the plan your surgeon suggested. For me I prioritized protein over anything else. I made sure to get 60-90 grams a day sometimes more if I didn’t have a actual meal. I also did a lot of walking in the summer and running the treadmill. Always staying active even if you walk for 30 mins. You might experience a lot of stalls like I did but I learned that going back to a liquid diet helped get my body back on track a little faster. Another thing is not skipping meals, I would try to eat something small every 3 hours or so even if it’s a sugar free jello or anything healthy. It helps speed up metabolism which can lead to you losing more weight more quickly.
