humans only began an diet based on agriculture 12,000 years ago which is not long enough for any real evolutionary adaptation
BABOW, try again.

It is the diet our bodies are designed by evolution to eat.
That's a fantasy. There was no single Paleo diet; you're taking about the time when humanity spread over most of the planet. The diet changed dramatically for different groups (and hey, we're adaptable) partly because of their migration and partly because of technological change, which affected what they could eat and how they prepared it. There is no evidence at all that any one of the varied diets being consumed over that period was something that humans had specially evolved to eat. It's a supposition. The argument that any of those diets is automatically better than a healthy modern diet is also completely without evidence. We live longer and have completely different lifestyles. Carbs became a large part of the human diet because we started doing much more physical labour, for example. It was a smart thing for manual labourers to eat. That's changed again for developed nations in the last 100 years, but we're still living a very different life. Paleo man rarely survived past his mid 30s, so his diet could have been full of things which exacerbate senile dementia, osteoporosis or type 2 diabetes and it just wouldn't have mattered. Matters a lot to us.
And none of this is being debated in the paleo fan club, many of whom are just too in love with the fantasy of being a modern caveman. Paleo is the tribal tattoo of the diet world. In fact, if you see a guy with tribal tats in the gym, he's very probably eating Paleo. And while the diet itself is probably quite healthy for most people and certainly better than the standard diet, it's just not good to have a diet whose rules are determined by pseudo-science which is being defended for emotional reasons rather than being properly studied.

no.. just no.
Human biology is not a simple machine.
Calories in vs calories out does not = health.
Lets not even mention the psychological areas for now.
Its this kind of gross over simplification, that has lead to a world of chronic obesity.
We are continually now discovering how complex, which is why new findings lead to conflicting advice.
Paleo is not scientific.. and does not try to be.
It simply points out that humans only began an diet based on agriculture 12,000 years ago which is not long enough for any real evolutionary adaptation.
The previous 90% of human history was a diet based hunter / gathering, meat, nuts, fruits but no refined carbs.
It is the diet our bodies are designed by evolution to eat.
Probably more likely to benefit your fitness and survival.
True not an empirical argument but a logical/rational solution when the evidence is incomplete.
Asumming you believe in the power of evolution.
