@ Ekdog
NO I was never more than 177 lbs on my 5' 8". That isn't even plump. I don't get tripples or mega meal addons.
For 20 years I had a very aeorobic job in woodwork. The last 5 summers I struggled to not get skinny from 4000 cycling miles avg. Most years I was around 166. Actually it's chocolate bars that add the weight fastest, I've had plenty of them too.

As for healthy eating, avoid DIET soda poison like the plague !!! 3 years ago I quit drinking soda/Pepsi with the fast food and haven't had acid indigestion since. Juice has the same sugar I hear, but it doesn't disolve your bones.

There are several guys who eat almost nothing but McD and one guy "collects" McD locations by the thousand.

PS When I was about 50 my DR. said I had a heart like an 18 YO.
Now my BP is i bit high.
