Cognitive dissonance and confirmation bias

I have a number of rant posts lately (and you should see those that I am not publishing), probably because I am doing a lot of research on my book. Today’s post was triggered by an article that I found really funny because its author was complaining about cognitive dissonance in others, whilst being the co-author of a paper that in my view is the mother of cognitive dissonances when it comes to justifying the use of HIT in a training setting.

Are HIGH carb / LOW fat diet better for fat loss than low carb / high fat diets after all?

Paleo 2.0Don Matesz has this new post up that goes directly against the “conventional wisdom” of the Paleo community, at least the likes of Mark Sisson, Kurt Harris, That Paleo Guy Jamie Scott, etc. Now clearly, Don is on a mission to show that Paleo does not equal low carb – but just because he is on a mission does not mean that he is wrong. And I believe that we in the Paleo community must be very careful not to establish our own “conventional wisdom” and try to defend it against objective evidence provided. Continue reading

What yogurts to buy for my five year-old daughter?

Paleo 2.0I have been thinking quite a lot about how to make my daughter eat healthy – or rather, reasonably healthy. She attends probably 2-3 birthday parties per month, where there is invariably loads of cake and ice-cream, and of course there is the school lunch. Anyway, I was going through the dairy aisle at the local supermarket, and I looked at the various desserts on offer.

Now clearly neither of those desserts would qualify for Paleo, Primal, or even Paleo 2.0.  Having said this – I do believe that active children are different in the respect that they are able to tolerate more sugar than adults are, especially if the fructose content is kept in check. Also, it must be kept in mind that an apple for example also contains 20g of sugar, about 75% of which is fructose. Yes, it also contains other important stuff, but so does yogurt. So, interpreting Paleo 2.0 as “reasonable eating” I would say some of the below desserts do indeed qualify.

Healthy fruits – Fructose content edition

Paleo 2.0I put together a list of fruits and their fructose content, in relation to their overall carbs content (carbs usually being glucose). The idea here is that healthy fruits should (a) minimise fructose, and (b) minimise sugars overall. Continue reading

Grazing – Is it better to eat 3x or 5x per day?

Paleo 2.0There is an almost religous debate going on between people that claim you should be grazing (more Zone’ish folk) and those that say you should be eating no more than 3x per day (more Paleo’ish folk). IMHO this is a bit like discussing how many angels can dance on a pin. In the spirit of Paleo 2.0, I’d say that this is one of the parameters that are up to you personally, it is not core of the diet. Continue reading

Archevore Diet and Paleo 2.0

Paleo 2.0It seems Kurt Harris has decided to call his approach Archevore. I am not sure whether this is replacing Paleo 2.0, or whether Archevore will be his flavor of Paleo 2.0, like Primal Blueprint is Mark Sisson’s. (UPDATE: from what I understand it is the latter – P2 is the framework, and AD is his flavor of it)

Paleo 2.0 – The Name

Paleo 2.0This is more of a comment for Kurt Harris’ blog, but I am still in two minds about what I am about to write, so I’d rather have the opportunity to edit it. The thing is – I am not too fond of the Paleo 2.0 name and I think we should eventually change it. But just to be clear: this is not the priority – the priority should be to get the content right first and foremost. And I am actually rather excited about the fact that this is happening right now!
