I will tell you what changes I made.
I stopped eating junk "indiscriminately". What I mean by that is-I do sometimes have junk, but it's either the light version or it's for a special occasion, like a sliver of my niece's birthday cake. I will NOT eat it just because it's there in front of me. I am trying to keep that promise to myself. If I really REALLY want some, I will have it, but most of the time, I don't even really want it anyway.
I also stopped eating regular food indiscriminately. I have to keep track of what I'm eating, at least in my head.
I will NOT allow myself to get too hungry. I'm eating something every couple of hours. My blood sugar seems too sensitive to go too long without eating. So I tried eating smaller amounts more often, and lo and behold, it worked for me.
I never starved myself. In weight loss mode, I started out at 1500 and my nurse practitioner told me that was too low for me so I raised it. I'm now around 1900 a day and holding out at around 145 lbs.
I can live with that.
It's now always easy, but I have (I hope) convinced myself that every meal does not need to be a "feast", which seems to be the way I was living before. The very hardest part for me is restaurants, and not because I really want to eat the huge portions of junk, but more because there seem to be so few sensible options available.
I also exercise a little, but not nearly enough.
Losing weight was not that difficult. It truly is keeping it off that is the toughest. I wish us all strength in this constant battle!
Oh, and I never believed in a "magic pill" LOL and never took any weight loss supplements. Just multivitamins!
edited to add: I'm glad I don't really like fast food or hot dogs/cold cuts/sausages/any kind of strange meat. It saves me a lot of grief! LOL Easy to avoid b/c I don't even like it!
