What is Causality

“You need to be healthy to lose weight, not lose weight to be healthy.” So begins Diana Schwarzbein in her book “The Schwarzbein Principle: The Program”. Although this blog is not an endorsement of Schwarzbein or her program, it is a look into what we can learn when we let go of our concepts, open ourselves up to new sources of information, and keep a critical perspective.

And today’s topic: causality... or more specifically: the direction of causality. We’ll be focusing on causilty as it relates to obesity. The beauty of Schwarzbein’s statement is that it reverses the direction of causality. The direction of causality as it relates to disease and obesity is something we’ve always implicitly taken for granted. Yet, here’s an M.D. achieving clinical results telling us that in her experience, it works the other way around. Unfortunately, “what causes what?” is a question we need to ask a lot when it comes to health and nutrition.

This is just a short post, intended to spur your mind in a different direction. I will summarize it now, with a couple images to visualize Schwarzbein’s statement.



This is the current model. I’ve never been able to find an adequate explanation of how the extra fat tissue, just sitting around there, is causing these diseases, but hey, look at the bright side: With this model you get to take all the blame when the model your diet is based on is proven wrong (oops, I mean when you fail the diet)!



A different model. Note that in this model “undesired fat storage”, “increased appetite”, and “low energy” are results, not causes. Furthermore, they don’t maintain any direct links with each other, which means that you don’t affect one result (undesired fat storage) by ignoring another (increased appetite). I don’t have anything to indicate that this model is incorrect as opposed to the overeating model. In fact, my research has lead me to believe this model is more correct. More to come on that. And intuitively, to me at least, it makes more sense.

Finally, I want to make one more addition to the diagram that the research so far seems to support.



Again, more on these themes in future posts.
