Did you see the latest study...

So lots of people are always asking me things about the latest study they just read about in the news. Did you see that people who work out are smarter? There's another article about how meat causes cancer, did you see that? What about the latest report where they said the paleo diet will kill you?

My response is usually two fold: I roll my eyes and then begin with "Well how it really works is..." [In grad school, I killed a lot of parties by using that quote. It's hard for a physicist to not tell people how things really work.] I'm not really good at explaining why the latest study is wrong, but it usually falls into a couple of categories and I try to explain what would typically be wrong with a study. It usually goes over as well as my explanations in grad school went.

I came across this great article yesterday that actually picked apart one study as a case study in why you can never trust the "science" that's reported in the news.

So here's the headline: Diabetes expert warns paleo diet is dangerous and increases weight gain.

Well that sounds pretty scary, especially since I'm an incredibly strong advocate for a paleo approach to nutrition.

But it's all wrong and stupid. Here's the whole take down, and I think you should read it. Below is my meta-summary:

The conclusion of the study is "a low-carbohydrate, high-fat diet for just eight weeks can lead to rapid weight gain and health complications".

How did they come to that conclusion: they took a special breed of mouse that is genetically selected to be an obese mouse. One group of mice is fed a high carb, low fat, low protein diet of mouse chow, the other group gets low carb, high fat, high protein. That fine so far, granted this a mouse study and they're special mice that are designed to be obese.

Now here's where it gets weird, they actually classify the high carb, low fat, low protein diet as the "paleo diet" and the other as the control. Now there's nothing that says paleo diets are low carb, high fat, but go back and read the conclusion of the study, and the headline. They are equating paleo with low carb, high fat, but in the study the "paleo" mice get the high carb, low fat.


So what do we get? "Paleo" mice from a breed designed to get obese are overfed and they get fat. Somehow they come to the conclusion that free-eating humans are going to get diabetes from a paleo diet. Why? Look at the funding, it's funded by folks who have a vested interest in medication rather than sensible diet solving illness.

I can't do the whole take down justice in a short blog post, you really should read it.

What really makes me mad is that crap (at best), intentionally deceptive (at worst) science is then reported poorly in the media. This happens over and over again and makes my job harder since no one will believe me because I disagree with the "experts".
Workout
strength - add weight from last time (more info) 

deadlift 2x5 

then

3 rounds of 

1 min - deadlift (~50% of 1RM)
1 min - push press (~50% of 1RM)
1 min - row
1 min - wall ball
1 min - carry
1 min - rest

Keep moving but always be going slow enough that you could keep up a conversation. Don't stop and rest, but don't get out of breath. This is a long, low, and slow workout.
