CW: Eat small portions regularly.
Primal: ? Eat when you're hungry (some of us only eat 1 meal a day and get all our calories in, to boot!)
CW: Eat more calories in the first half of the day because calories consumed before going to bed transform in fat.
Primal: ? Eat when you're hungry (yeah, breakfast no longer exists on Primal)
CW: Carbs in the morning, proteins in the evening
Primal: ? Fat & protein all day long (when you're hungry), limit carbs to 100 or less for weight loss
CW: Drink at least 2 liters of water a day. Some radical nutritionists even recommend 30 ml per 1 kg of weight.
Primal: ? Drink when you're thirsty. Personally I try to drink half my body weight in ounces daily.
CW (probably not generally accepted, though): Do not mix fruits and vegetables in one meal. It is best to eat fruits on their own.
PB: Chow down on veggies, limit fruits. You COULD eat them together, but... why?
CW: Frying is unhealthy.
Primal: ? Depends on what you're using. A little dredge in egg and coconut flour once in a while, cooked up in bacon fat or coconut oil won't hurt you. If you're honest-to-goodness-ly absolutely craving fried, do it that way (JMHO). Try to choose healthy oils like coconut & EVOO
CW: It is essential that you start your day with a good breakfast.
Primal: ? Eat when you're hungry (LOL, funny how that keeps coming up). If you're hungry in the morning, eat. If you're not, don't. Pretty simple.
Primal is about healing yourself and learning to listen to what your body needs. The Blueprint just gives you the tools to do it.
