However, plenty of nutritionists have pointed out that going (cooked) low-carb just means losing a lot of water-content as carbs increase water-retention..

So people who lose 100+ lbs have just lost water weight? Weight loss at 
the beginning of a low carb diet is mainly water...as id the weight loss 
at the beginning of any diet.

After all, 100 years ago, they had much higher activity-levels so would have been better placed to work off the fat gained from eating cooked foods(plus native tribes from 100+ years ago, didn't overcook their foods like we do, which would have helped re weight-loss.

I am seriously still waiting for some science here regarding cooking 
causing obesity that controls for what TYPE of food is being eaten. By 
what mechanism does this happen? What actually happens in the body? We 
have a good idea of the relation to insulin/hyperinsulinemia etc and 
obesity, and science going back 100 years that demonstrates this 
reliably (and can be replicated over and over). We also have science 
that demonstrates (and has been replicated) that calorie content and/or 
energy expenditure are corrolated with obesity, although not a cause 
(often, they are a result). Taubes lists numerous studies that have 
found this, for example (and that obesity/weight gain is a symptom of an 
underlying metabolic disorder, and one that not everyone will exhibit)

I see a lot of speculation regarding cooked vs raw foods and obesity, 
but not much in the way of science to back it up. There is quite a bit 
of evidence that HG tribes, once they started eating modern foods, also 
started experiencing diseases of civilization (diabetes, etc) and 
obesity...but none of it that I've come across demonstrates that the 
reason for this was due to transitioning from a diet of raw to a diet of 
cooked food. If there is evidence of a people gaining weight and 
experiencing disease after a transition of raw fat meat to cooked fat 
meat (and nothing else, like bread, jam, sugar, etc), I would love to 
see it. I really would, I am not being facetious here. That would tell 
us something.
