Good for you Stan, 18 pounds is well on your way. Have you tried a carnivore diet? Or just some variant of keto? I wanted to come out of COVID minus 19 to 30 lbs myself see what I did there .
IMHO carnivore is the only satiating way to eat, but any way you lose it and keep it off is great.
I miss my custom made Marinoni super record 1983 version a lot these days, As I live near a bike path for the first time in my Life my mountain bike gets little use though.
