Why would you ever have a carb and veg meal with no protein? That doesn't make any sense to me at all.
You dont HAVE to have them separate but its better for digestion. The stomach has a certian level of acidicty for breaking down different foods. Protein molecules need a higher acidity to be broken down than carbohydrates. So when you put them both in together, the stomach gets confused as to what to do. Usually it swings back and forth between high and low acidity, and basically u end up with that 'heavy' feeling in the stomach and your food takes a longer while to digest. because ur food is in your stomach for longer it loses alot of its nutrition, sitting in hydrochloric acid as it is
Our stomachs werent designed for that, as our ancestors didnt have the lovley choice to have a meal of many different parts lol.
Think of it in terms of fruit. You put fruit and meat in at the same time, and the fruit, which usually passes straight to the small intestine for quick absorption, is forced to sit in the stomach by the dense meat and loses its nutrition as it ferments and becomes toxic, rather than alkaline and beneficial to the body. Thats why fruit should always be eaten alone on an empty stomach at least once a day.
These food mixing rules arent life or death, but they do go a far way for good digestion, health and getting the most out of ur food. Its quite easy to structure...e.g
Meal 1- Carbs and veg
Meal 2- Protein and Veg
Meal 3-Carbs and Veg
Meal4-Protein and veg
Meal 5-carbs and veg
Meal 6-Fruit (4-5 pieces)
Following a method like this, a good portion of your diet is raw unprocessed vegetables with plently of vitamins, minerals and fibre, you get an alkalising effect as you go to bed when the fruit cleans your system, and you get all the carbs and protein you need

I learnt all this through study of detox's, holisitc medicine and the advice from nutritionists and naturopaths, but im not saying it has to be done this way its just the way i like to do it
