4.a.healthier.me, don't get discouraged. It's a lifelong challenge for us. The number of times I've done that are too numerous to count.
I think the biggest thing I've done this time is I've kept exercising. I run every day with my kids' cross country team. The kids are my biggest fans, and I feel like I'm letting them down if I don't do the run.
I think if you can make yourself exercise consistently, then the lapses don't do as much "damage" to our weight loss.
Keep at it, and remember, this is a lifetime thing, not a two or three month thing. One month, is one month. You can redo what you undid. I know you'll do it.
Started at 300 lbs., now at 221, going for 150.
