68 year old with new knees and shoulders which will require replacement in the next few years. Sticking with a medium to heavy weight routine for exercise but starting to use heavier weights for some exercise. Nothing over 315 lbs and only 4 days a week. I eat a modified KETO diet with more protein and less fat than is recommended and lots of veggies. Have always had weight issues and I put on weight very easily. I am down about 60 pounds over the last 18 months but the last 10 pounds has been a challenge. I think I may be adding muscle which is complicating the losses but will just keep on.
