I had my SG at the age of 52 and I am now 55. I lost from 245 to 225 before surgery. Then after surgery I lost down to 165. After that I gained up to 202 on snack foods etc. but went up gradually until a couple of months ago. The VA had a re education class called bariatric back on track class. I lost down to 191. The surgery went great for me. I broke my arm in 2014 at the head of my shoulder. A steel plate and 14 screws from surgery and It healed completely. I attrubute it to the Vitamins I am taking religiously not to mention all the Protein we have to eat. I can't eat any complex carbs and loose any weight without vigorous exercise. Metabolism must have been rock bottom. It is much better now.
My plan of attack has been 3 ounces of protein and a watery fruit at every meal and I have lost on average of 2 pounds per week. 3 meals per day. I have also found eating 3 dates per day helps to keep me regular not to mention curbing that sweet tooth.
