Guys, I just tried Costco sour cream for the first time...

IMO ... COSTCO has quality pickings. The only downer there is in fresh produce, bakery and dairy where everything is packages in sizes far beyond the the consumption ability of just one person. Yea, I probably could consume an 18" apple pie in two or three days if really tried, but in general it's best for me to bypass those areas of COSTCO and focus on the seemingly endless options of great frozen and vacuum packed items.

I'm dying of starvation reading about your diet. I would get exhausted chewing enough vegetables to get my daily calories.
