David, you and I have a lot in common. (Read on.)
I consume low-fat dairy regularly too. This isn't always popular, maybe you and I should pen an article on its myriad benefits.
And I, too have pop tarts in the cupboard. (My wife thinks they're for my son but I've always had a peri-workout soft spot for them in the tradition of Tom Platz.)
After umpteen years of eating cans of tuna twice a day, I had to get increasingly creative to get it down. Ultimately, recipes flew out the window and I just slammed it with OJ right there on a bench in the gym. I don't do eat it much nowadays. Two-three times per week maybe.
