I disagree. A lot of the time, our instincts are not truly natural - whereas wild animals seem to instinctively find the right kind of nutrition for most of the time.
Of course over the long spectrum of their lives, wild animals instinctively choose their proper foods, but not if there is a shift in their environment or a drastic artificial change in circumstance or most importantly a choice in food supply. A Bear with the faculty to call Honey Pacifica would eat more honey than it needs in its diet and as long as it was readily available without effort. It doesn't stop eating fish with the idea that it can go to the store and pick more up if it goes bad.
as for weight-loss this sounds totally ridiculous in contrast to your argument - unless I perceived it wrong - that paleo men had far greater functional strength than Olympic lifters. wild animals are able to have huge muscular builds eating their biologically appropriate diet, whether plants or animals. They often consume a very specific and often large amount of food to maintain this equilibrium. Unless one is to believe humans are from outer space with other requirements, which is possible, they too have these requirements.
I don't see this as anythign other than the same logic proposed by vegans, that 'normal' SWD eaters are 'overweight'. Of course on a tissue level this has truth, but theoretically according to the proposed models, that once one become pure enough and emptied of these toxins, their bodys become full and healthy, often proposed regardless of intake. I spouted this garbage for years and have yet to see one concrete example of a person as majestic as an animal in this respect. So either this pursuit of cleanliness is largely impossible, OR the entire idea is just wrong, including the ideas of what constitute our natural diet. Clearly people are less than convinced here about the possibility of such eating only plants, so it makes the argument for eating RAF fairly poor if the outcome is essentially the same in respect to this issue anyway. Just because some might as they become healthier absorb more food and require less than someone unwell, does not change the fact that others might need that extra food to maintain healthy weight, no matter how pure their instincts become, because there is never a situation where those instincts manifest as per above.
as for the aesthetic element, I guess the photos of modern HG's and Native Americans, and Greek statues are all we have to go by, even though they all ate cooked foods. I think this comes down to again, looking at other animals and their weights/builds/and densities and if so that this theory is again largely mistaken. I know with myself my numerical weight I've heard is way lower than to the eye, however even still if I was to play a role in a film, like a fit thin Average Joe or something, I would probably have to gain 15 lbs. Of course again that is comparing it to 'toxic' people, but if one is truly healthy, than weight gain, like it is for expecting mothers, should be an effortless endeavor on our true natural diet. Its fine to be thin, as long as they are truly healthy enough to gain on natural raw foods and not hiding behind some notion that can't be possibly accurate for clean
or ancient humans re: raw foods and weight-loss. Again this brings up basic suspicious about the contents and quantity in the diet being adequate for building OR cleansing. Only in health, what people CHOOSE to be at that point is their own business.
