I'm 60. I've lost 55 pounds in the last 18 months and have at least 10 left to go. The laws of physics apply no matter how old you are. I tried for several years to lose weight, and then all of a sudden I got myself in the right place mentally, started eating right and exercising more, and the pounds came off. I'm fitter now than I've been since I was in my 20's, and I feel 10 years younger than I did a year ago. It's never easy, but it is so worth the trouble.
