You've lost a lot of weight, but still have a distance to go. You work out, eat the right things, and yet you've stopped losing weight.
Change something. You are at this point because your body is comfortable. Try a new workout routine, switch out your meal plans.
Do something DIFFERENT
Try group fitness "boot camp" style classes at your gym - rarely the same workout twice, and it will keep your body guessing. If you have a comfort food you've worked into your calories, drop it or replace it to get that extra bump you need to start losing weight again!
