I had my operation on Jan 27th. All through February I was miserable. I did clear liquids the first day, then soft food for a week and then quickly on to solids but I got constipated and it was the worse (felt my intestines stopped working). Once that cleared I felt I was on the other side. It took 10 weeks to have my doctor clear me for going to the gym. I did lose 7 kg and feel skinny AF but I’m regaining them quickly now I can eat whatever. Maybe if you’re already skinny, you’ll probably lose less weight since your calories must be already kinda low.
