With a little bit of time to mull it over, I think that I can provide a real answer to
@NurseDave 's question as to my motive for gaining (healthy) weight.
When I was in my 20's and early 30's, I used to be in REALLY good shape. Football ("soccer" for most North Americans) was 4 x a week (2 practice, 2 games + coaching youth) had me with solid cardio as well as leg muscles , abs and even enough lats to provide a mini-V back. 20 years ago, I left 8-4 office work and started consulting/contracting on my own, which led to long hours (most weeks were 50+ hours, with 60-70 ones not uncommon). Good money but it basically meant that I had to stop football as I could no longer meet my commitments, especially as a youth coach. 16+ years of that resulting in me developing a small "office belly," chicken legs, and losing just about any muscle definition that I had.
I don't think that it would be healthy for me to try to go back to the lean 130-135lbs I was in my early 30's, as that would mean losing 25 lbs, but I least I can try to get in shape again ... and that means feeding my body enough carbs and protein to facilitate healthy muscle growth. I don't eat very much red meat at all, preferring the taste of M&M veggie burgers over beef, and that probable leaves me a little protein deficient in my diet as I'm not a big fish fan and eat chicken maybe 2-3x per week. I'm basically about 75-80% vegetarian by choice.... I simply like how the food tastes rather than for any other reason (spiritual, animal rights, etc...)
My daily exercise is going well (I think) and I've dropped 2 inches from my waist over the past 2 months (started in early Dec) and I'm now a 31-32" waist. My legs got skinnier but more defined, as did my arms. Alas, I'm always hungry and my muscles started to "tingle" if I tightened them, which is most likely because they are not getting enough fuel to recover.
So basically, my weight gain goal is to pack on a healthy 10lbs of muscle (20 is my stupid "reach" goal) and start to get back into some sort of shape that resembles where I used to be. Not looking to enter any Mr. Old Fart Bodybuilding Championships
