New York Times Magazine Article on Obesity

Wednesday, January 4, 2012
For those of you who haven't seen it, Tara Parker-Pope write a nice article on obesity in the latest issue of NY Times Magazine (1).  She discusses  research showing  that the body "resists" fat loss attempts, making it difficult to lose fat and maintain fat loss once obesity is established.

High-Fat Diets, Obesity and Brain Damage

Monday, January 2, 2012
Many of you have probably heard the news this week:

High-fat diet may damage the brain
Eating a high-fat diet may rapidly injure brain cells
High fat diet injures the brain
Brain injury from high-fat foods

Your brain cells are exploding with every bite of butter!  Just kidding.  The study in question is titled "Obesity is Associated with Hypothalamic Injury in Rodents and Humans", by Dr. Josh Thaler and colleagues, with my mentor Dr. Mike Schwartz as senior author (1).  We collaborated with the labs of Drs. Tamas Horvath and Matthias Tschop.  I'm fourth author on the paper, so let me explain what we found and why it's important.  

The Questions

Among the many questions that interest obesity researchers, two stand out:
  1. What causes obesity?
  2. Once obesity is established, why is it so difficult to treat?
Our study expands on the efforts of many other labs to answer the first question, and takes a stab at the second one as well.  Dr. Licio Velloso and collaborators were the first to show in 2005 that inflammation in a part of the brain called the hypothalamus contributes to the development of obesity in rodents (2), and this has been independently confirmed several times since then.  The hypothalamus is an important brain region for the regulation of body fatness, and inflammation keeps it from doing its job correctly.

Junk Free January

Sunday, January 1, 2012
Last year, Matt Lentzner organized a project called Gluten Free January, in which 546 people from around the world gave up gluten for one month.  The results were striking: a surprisingly large proportion of participants lost weight, experienced improved energy, better digestion and other benefits (1, 2).  This January, Lentzner organized a similar project called Junk Free January.  Participants can choose between four different diet styles:
  1. Gluten free
  2. Seed oil free (soybean, sunflower, corn oil, etc.)
  3. Sugar free
  4. Gluten, seed oil and sugar free
Wheat, seed oils and added sugar are three factors that, in my opinion, are probably linked to the modern "diseases of affluence" such as obesity, diabetes and coronary heart disease.  This is particularly true if the wheat is eaten in the form of white flour products, and the seed oils are industrially refined and used in high-heat cooking applications.

If you've been waiting for an excuse to improve your diet, why not join Junk Free January?
