Peas are a legume and if I said eat peas that's all people would eat. They are higher in carbs than a normal veg (Which in a balance meal after this program is awesome). So yes, peas are natural - I eat them at least 5 times a week. However each day has a carb balance that must e maintained. Once again if I said peas were OK, then people would not just eat a few, they would eat only peas, also carrot and corn.
Let me ask you this first, do you think a machined, normally rancid oil like sunflower in a plastic bottle will not cause weight gain. My suggestion is to study the health benefits of coconut oil. Basically it goes straight to the liver (most of it), doesn ot have to be processed by the gallbladder and gets used as energy. These machined junk oils were needed when the US went to war (WWII), the Philipines were a part of it, so no more coconut oil, so we had to invent our own, over processed oils.
Green beans are OK in moderation. Beans/legumes are not until after the program unless you use them as a meat replacement.
