I know where you are coming from with having to lose weight before your surgery. I thought the same thing you did. If I haven't been able to successfully lose weight myself for the past 25 years, what makes now any different? The difference is that you really aren't dieting this time. You are making a total lifestyle change that you will need to follow from now on. I lost about 12 pounds in 3 months with my doctor supervised diet and that was before I made any diet changes that I will follow from now on. I met my surgeon after my 3 month supervised diet and he gave me some tips and so did the NUT. I was told to cut out all soda and sweetened beverages. Also no carbonated drinks. Increase my water or non caloric beverage intake to at least 64 oz a day. Try to cut as much sugar intake as I could and lower my carb intake too. Doing all of that made a huge difference for me and I lost some weight as I changed over. Finally, I started walking everyday. I just walked around my neighborhood and worked my way up to 4 miles a day-2 miles in the morning and 2 in the evening. Walking made a huge difference and it is important to your healing process after surgery. I decreased my pain immensely by getting up and walking as much as possible after the surgery. And lastly, I tried out my liquid diet about 2 months prior to my surgery date. I did it for 2 weeks and lost 18 pounds prior to surgery. You can do this! This is a life changing experience and is so worth it. Good luck to you! [emoji3]
