Can the guy on the right run away from the bloated macrophage coated fat cells on the left? Today's first post in the SuppVersity Exercise Science Week does hold the answer to this existential question. Those of you who don't just read, but also think about the headlines of these posts will probably already have theorized about the remote possibility that I could have changed my mind and discarded the original plan to do an "exercise quickie" early this week (see SuppVersity post from Saturday ). Now, before you are getting mad at me, let me give you the (as I would say good) reason for doing that: Some, if not almost all of the exercise related studies, I have piled up here are actually too interesting to end up as part of a mash-up. That's particularly true in view of the fact that my time budget during the week does not allow me to discuss them in appropriate detail. So, even if wanted to end up writing >10,000 word posts, this would only work on 48h da...

Image 1: To eat or to diet, what's worse? Despite the fact that the magazines are still full of "X pounds in Y weeks" diets , more and more people begin to realize that "diet hopping" and even "dieting" in the conventional sense, i.e. following a special, usually very strict and non-sustainable nutritional regimen for a very short amount of time, are futile. But can calling a halt before you blow up like a balloon from time to time actually be worse than letting yourself go all-day, everyday? According to the results of an experiment that has been conducted at the Institute of Biology of the State University of Rio de Janeiro , the results of which have just been published in the open access journal PLoSOne , the answer to this question must be: YES, it can! And that may be true, even when you are not starving yourself! Even "healthy" weight cycling turns out to be profoundly unhealthy! Now, the unfortunate news first: We are, as ...

An In-Depth Look at How You Get Fat: You Acquire More Rather than Bigger Fat Cells

Written by | published on
Scientists from the National Institute of Health in Bethesda, Maryland ( Jo. 2010 ) have investigated the exact cellular pathways of weight or rather fat gain. They report: We found a qualitatively universal adipose tissue remodeling process in all four fat depots: 1), There is continuous recruitment of new cells under weight gain; 2), the growth and shrinkage of larger cells (diameter >50 μm) is proportional to cell surface area; and 3), cell loss occurs under prolonged weight gain, with larger cells more susceptible. It needs some interpretation of the results to understand their significance in view of staying lean in the first place . Normally, you would mean it does not depend if one fat cell holds a certain amount of fat or if this fat is held by two different cells. Unfortunately, it is a) much easier to "empty" one big fat cell which is about to burst anyway than two smaller cells and b) even if you emptied them completely that would leave you with more fat ...
