Interesting thread!
I have always eaten (forty-five years) a certain number of protein grams every three hours and now it's about eighteen grams per serving. I eat out at sit down restaurants once or twice a day, but I save at least half of each meal to eat later or the next day. I don't have near the appetite that I used to have, thank goodness, so I'm about the same weight I've always been (6' 1" 190), but I have noticed the quality is slowly changing, lol.
I don't eat much fast food and I don't like soda, but I do like a bit of something sweet after most meals, although I"m not enjoying Little Debbie as much as I used to. I start the day with the same protein drink I've used since my twenties (mostly powdered milk, whey, soy, whatever) and things seem to be going fine.
My restaurant eating is with friends, all of whom are a variety of vegan, vegetarian, pescatarian (I'm mostly this), etc., so each place we eat is somewhat designed around their needs. I don't particularly care as long as it's not the same thing two days in a row. I cook on the weekends to spread that between my "doggy bag" meals and I cook everything from paella to oriental, changing up from meat to vegan meats whenever I feel like it.
My training is going very well, but my recuperation grows more difficult by the year and that is a little discouraging. Because of this thread, I"m going try sardines again!
I don't eat peas nor do I consider them a credible food source, but I eat pretty much everything else.
