I've lost 80 pounds in the last year, and I've lost 50 pounds of that in the last 5 months. Last year, I lost around 40 pounds, but I wasn't on a good diet and exercise plan that worked for me. Only around 30 pounds of that transferred over into what I've lost now because I started to regain weight early this year. On May 20 of this year, I started strictly and very accurately counting my calories and wearing my fitbit every day, and it has been working very well for me. I feel much better than before and I still have another 60 or so pounds left to lose before I'm actually out of the obese category according to the traditional BMI. I think I will feel much better after losing another 60 pounds. The differences between me and you are that I'm probably a bit younger, and I'm fairly healthy aside from being obese. I've turned my diabetes around, which was my biggest concern other than my weight health-wise. My A1C was checked last month at 6.2 which is down from being over 12 when I first noticed I had diabetes. It's type 2 by the way. I also notice a bit of pain from walking, but it's easy to manage with Ibuprofen or Tylenol, and it's not an everyday thing for me. You should listen to your body and give it a rest if you need it. Don't do too much at once, take breaks from walking. I'd suggest maybe walking for 30 minutes 4x per day rather than 1 hour x2 per day. I know it's hard to make changes after you get a routine going, but it might be worthwhile to experiment a little with the length of time you walk and the number of times you do it. I walk for 30 or 45 minutes for 3 or 4 times each day.
