Ok I am making a different post for it but I found one of the things I was thinking about. Question was "why is phase 1 on P90x high protein"
"Phase 1 of the diet plan is not designed to put you into ketosis--at least not for very long. It's designed to, essentially, wring the carbohydrates out of your system until you have trouble with the workouts. At this point, you begin to add them back in. In our experience this is the best way to teach people about nutrient ratios because once you do this you'll understand, by experience, why carbohydrates are important in your diet.

Unfortunately, we don't really address vegetarians and, especially, vegans. There are a few reasons for this. Primarily it's that those who take the time to eliminate meat already have an understanding of how nutrition affects the body and, two, they are far less likely to be overweight. There's also the issue of bulk of information. We would really need to write a different book.

This is always an issue when designing one program and one diet for everyone. It's impossible to cover every individual need. This is why we offer support areas, like the Message Boards. We do the best we can within the medium we work in. It's not individual consulting. But you can't get an individual to train your for 12 weeks and monitor your diet for 150 bucks either. You'll get two one-hour sessions."

My friend has been vegetarian for 30 years. Her husband is not vegetarian. However your kitchen is your kitchen. They do not bring meat into the house (she is not vegan). He gets meat when they eat out. He often will have meat at lunch if he goes to the company cafeteria or out to lunch.

I think if you are vegan you shouldnt have to handle meat. If you decide to allow it in the kitchen, he should cook it himself. (I'm not vegetarian by the way)

But I dont think you should "try" to convert him. He knows how you feel. He knows how he feels when he eats what you cook. He'll either decide to do it or not.
