I had my surgery on feb 10. I had lost about 20lbs on the 3 week pre-op. I gained almost 10lbs from iv fluids and medicines. It took me over 2 weeks to lose those 10 lbs. I’ve since lost another 18lbs - in 5 weeks. I’d love for it to be faster, but any loss is great. I am also eating 600-700 calories a day. But I’m also not quite as active a I was in feb and March, what with the extreme cold weather and everything locked down. Sadly, some of us lose slower than others. That was the case for me before surgery. I always lost slowly, so continuing to lose slowly after surgery isn’t really all that surprising.
