Looking for 55 yr old (plus) types

Options
Currently on active duty, have been an out-doorsy guy for ever. New challenge, the extra pounds have been slowly creeping up in the last couple of months. Seeking someone willing to be a mentor/encouragement as I (will reciprocate) direct my energy towards this unavoidable aging process.
Am seeing a dietitian, do have a set regimen (daily cardio/body weight workout) in place. Workouts are conducted a minimum of 5 days a week. Willing share workout routine, food choices and the like. Would like to be accountable to someone during this period as its not as easy as it sounds, gong it alone.
If you are like minded please do not hesitate to respond. All replies will be responded too, thanks for your time, hang in there and Lets do this.
