Eating only 3 times a week? The metabolic breadth of the human body is impressive. I have a hard time eating only 3-4 times a day. I do 2-3h of solid exercise every day, so I burn a lot of calories. I'm pretty sure I could get away with less, but I'm fit, not getting injured, and doing a lot more than 99% of people my age, so not going to mess with my eating habits too much at this point. From what I understand fungus does not produce B12, it's only produced by bacteria. It's added to nutritional yeast ... to make it more nutritional. Bacteria in our (and other animals') guts do produce B12, but we tend to need extra B12 nonetheless. I don't eat meat aside from a bit of fish, but I agree that a little meat in everyone's (especially children) diet would not be a bad thing. It's best not to be puritanical or extreme when it comes to diet. We're omnivores after all. I have a pet idea that a real paleo diet would include insects and grubs, but not sure if there's much anthropological evidence for that.
