>> You're getting all this the wrong way round. When people make claims that stuff we've been eating for thousands of years (bread, cereals, grains etc.) are actually really bad for us, the burden of proof is on them. I'm not sure if this should also apply with stuff that we put inside our body. In any case, not all of us are willing to wait that long, while we obviously see problems with the status quo. I choose to rather just make a judgement call based on social cues. >> On top of that Paleo promotes some claims that are clearly ridiculous, e.g. that burning fat for fuel == burning carbs for fuel. They have totally different consequences. This is inconsistent with anything I've read on this diet, but would be closer to the Low Carb High Fat diet, which I agree would be detrimental to an intense training regiment. May I suggest that you and I were not introduced to the same paleo diet? I recommend that you look up Robb Wolf. >> Yes, eating lots of carbs is bad for you. So is eating lots of fatty food. Or lots of anything. Just eat lots of green stuff, and make sure you get adequate amounts of protein & carbs. To lose weight, make sure calories in < calories out. Oddly, this is very consistent with what is promoted in the diet. >> It mystifies me how otherwise-intelligent people can get so caught up in fads such as Paleo, backed up by flimsy pseudo-science. Attempting to belittle people who choose to try the diet doesn't make you smarter and certainly doesn't prove nor validate your arguments. >> My theory is that they appeal to the contrarian in us - after all, they're delightfully counter-intuitive in some ways (eating lots of steak can be good for me?!). That is indeed only a theory. On the other hand, maybe some of us actually do see some results. >> And if you still think it does, look up the diets of the top 10 athletes in basically any sport & explain to me why none of them are on Paleo. The diet is extremely prevalent in the crossfit circles (it's even increasingly overshadowing the official diet, which is The Zone diet) and mixed martial arts (many of my training mates switch to it prior to competition). During my own research I stumbled upon this interview http://youtu.be/r-WRn8UttXw?t=10m http://youtu.be/r-WRn8UttXw?t=10m (interview starts 10 minutes in the video, somewhere within the first 2 minutes after it begins Joe Rogan mentions having talked to many fighters who are on it). My take away: "otherwise-intelligent people" use the diet as a set of guidelines for improved health and quality of life. You can choose to take it as a religion, but then lots of things just get more difficult. If you practice a sport, you need to adapt the diet to the demands of your discipline. I recommend to look up experts who are more sport oriented (I mentioned Robb Wolf earlier).
