hello, I am 34 years old. this july will mark 8 years since i got the gastric sleeve surgery. i still always watch my carbs and try to maintain under 30 carbs. my lowest weight i got to was 180. currently at 210 lbs right now. i was at 255 lbs when i had the surgery. i have noticed my weight start to creep up, my clothes start to fit tighter. i did let go of the protein for a while last year and just maintained lower carbs. i admit i fell off. for a couple months now i have increased my protein intake and still maintaining a lower carb count. i have not had a carbonated beverage since i had the surgery. i do not take any medicine except for blood pressure medicine which is a 12.5g lisinopril everyday.
with my daily protein intake becoming normalized now, mainly in the case of protein shake and then higher protein meats throughout the day. high water intake, i am still not seeing weight loss. i see that it is staying about the same. my question is, has anyone gone through this or is going through this? is there something i am missing as far as supplements. i did get blood work done, but my doctor has not said anything about any abnormalities. i have read it could be low iron. i figured if i went back to the basics, high protein low carb and of course high water intake, i could see results. could it so normalized now that it will take longer to lose weight? physical activity, i do try to get in about 10,000 steps a day.
any help, advice, would be greatly appreciated. thank you!
