I hate to ask this question but I am month 4/6 in pre-approval process. My whole life I have tried anything you can think of and I have been so very sure each one was the answer. I usually lose between 8-12 pounds each attempt and then stall. It's been the same thing pre-op. I did intermittent fasting with being gluten free since 7/31/19, no problem fasting 20-22 hours but when I would try to do alternate day fasting or 24 hour fasting I would gain with the lower calories. I have researched starvation mode and most experts agree it does not exist. I ended up averaging 19 hours and plateaued at 12 pounds after 3 months and then started gaining again even with the fasting. When I did my pre-op I was at one of my lower weights (my weight plot looks like shark teeth) and was told I was not allowed to gain at all during the process or my surgery would be denied. As part of my pre-op I have continued intermittent fasting for an average of 16 hours but I also gave up all grains, dairy, sugar, and soy. I have lost another 12 pounds for a total of 24 but cannot get any lower. I've played with calories, food types, anything I can think of. I track all my calories and activities and range 1200-1500 being mostly on the lower end of the range and get at least 30 mins of walking 5 days a week. I have no emotional issues with food and am very disciplined. I do have Hashimoto's thyroiditis but my hormone ranges are good according to my bloodwork. My thyroid is almost not existent except for a large nodule so my endocrinologist wants me to have me thyroid removed in addition to the sleeve. My big fear is that there is something weird with my metabolism and that I'll have the surgery and not be successful. It sounds crazy to even say that but this is a support group and that is my truth.
