Second what Patti says, Lucy!
I've kept quiet a bit as I don't want to jinx anything, but I've lost about 5 lbs over the last month. I'm still not entirely convinced that I won't wake up tomorrow and it will all be back on! But it's now enough of a loss that I'm convinced I really have lost it. It made a big difference psychologically getting under 150 lbs for the first time in over a year, and I'm really motivated not to see 150 again now!
I've been walking an average of 13,000 steps / 5.5 miles per day in the last month (since the release of Pokémon GO - it really has helped!) and focusing on eating mostly vegetables, some fruit, and a small amount of meat. I mostly only eat one meal a day though, to make this work (though I'm trying now to take some veggie snacks to work with me to keep me feeling too full to want to make a cafeteria run!) As I've said elsewhere I don't really get hungry ever, or feel a need to eat more often than that, and I can stave off DP with bolus insulin, if need be, so it works for me. May not work for everyone.
I had hoped to see 145 before the start of the semester, but as the semester starts next Tuesday I doubt that will be happening lol! But I'm still hopeful that I can make 135 by the end of the semester, in 16 weeks. Though it will be a pretty stressful semester, I think, so cortisol may stick his nose in my plans (I am vowed not to stress eat, though!)
