I hit my goal weight: 215.
It took 7 months but I weighed an even 214 this morning. That's down 31 pounds from my weight of 245 on April 18.
The key component was modified intermittent fasting. I ate 600 calories a day on two non-consecutive days of the week (usually Monday-Thursday). The other days, I ate normally. Actually, I got rid of any "skinny" products. On non-fast days, I drink whole milk, eat full fat sour cream. No "lite" beer, and nothing artificially "low calorie" in my house. I'm not saying I pig out on the non-fast days. Quite the opposite: I think fasting has helped me gain control of my appetite.
The fasting seems to have had a positive effect on my overall health. Doctor says he's never seen such positive blood work from a guy my age. My mood is generally positive. For some reason, I feel more "in control" of my own life.
The walking/hiking/racewalking goes well. I've put in 1,100 miles since April 18 (yeah, I'm sorta OCD about logging stuff). The aches and pains in my knees and hips have decreased dramatically. They are not gone, but I seldom notice them. As my doctor says, "motion is lotion."
Since I've pretty much hit my goals, I am formulating some new ones. Even though 215 seems a pretty good walking around weight for me, I think I'm going to take it down to 195. I haven't weighed under 200 since my 20s. In college, my competition weight was 175-180. 195 would be interesting, but I'm 6'1" and, in my vanity, I fear the stringy old man look. We'll see.
As for the walking, well, more of the same but with more intensity. I've signed up for a half-marathon next June, so I'll be training for that. Depending on how that goes, I may do a full marathon later in that year.
