Hi,

first of all - your progress is amazing and you should be proud!
Yes, the weight loss does slow down, different for different people but this happens to everyone. It's healthy and normal.....we can't make out bodies lose in the speed we choose.....
Personally I've been losing 2 lbs every 8-12 weeks lately.........no 'cheating' and no changes in the diet at all. I'm OK with that.
Keep doing what you are doing, add more exercise if possible....and tell yourself this is a long-time thing......you will reach your goal for sure!

Good luck to you!
