Yes, that all may be almost true. Yet you're conveniently forgetting the vast majority of the population lives on little or no meat and people can be very healthy living on plant foods alone but try and live on meat and you will be dead in little time. If you ever manage to get passed the mega intestine blockage, that is.
That's questionable most will have problems with their hearts and their general workings, the vege we and they eat is hardly natural, most is breath for sweetness, carrots lettuce fruit are basic sugar pots as you would not eat the wild varieties.
The thing about diet studies they are so varied and contradictory, you can only ask what did we evolve to eat and the answer is cooked meat. Most wild vege is uneditable.
But in saying that the meat we eat is not natural it is to lean, we need animal fats and that's what fills us up, that is what the apitat responds to and tells us we have had enough to eat it doesn't understand vege or sugars or artificial fats and that's the real reason obesity is a growing problem.
Eat fat to get slim and healthy. Not Atkins which was a high protein diet what we want is a high fat diet.
