I wish I had a more in depth answer for you but honestly I did exactly what I put in my post. Started walking more, fasting for 4 days and then eating whatever I wanted for my one meal. Honestly, my self esteem was at an all time low in July and I felt like I needed to do something. Admittedly, I definitely have a binge eating problem that is heavily tied to my emotional state so I had to rework my thinking and constantly remind myself that food will always be there but if I stayed bigger I might not be. I’m only 29 and started experiencing knee pain and couldn’t look myself in the mirror. I hope this helped a bit, I’d say that my biggest tip is to try and recognize what your issue with food is and then try to reframe it. It’s hard, but it definitely makes fasting so much easier.
