Hey, everyone,

I’m going to be speaking at the EPIC Fitness Summit in Birmingham in the U.K. on May 17th.  I’ll be debating John Kiefer on the topic of insulin and whether it is a major contributor to the weight problems and other health issues we face in our world today.

The EPIC Fitness Summit is going to be a HUGE event.  It is from May 15 to 17, and the speaker line-up is absolutely amazing.   With speakers ranging from Alan Aragon to Layne Norton to Brad Schoenfeld, this event is guaranteed to not only educate you but knock your socks off at the same time.  Not only is the speaker lineup just awesome, but there are some world-class debates set up as well, with Alan Aragon debating Gary Taubes, Brad Schoenfeld debating Fred Hahn, and yours truly debating John Kiefer.  Check out all the speakers here.

Get your tickets to this event here.  In the mean time, here’s a short video of John and I talking about our upcoming debate.

Hope to see you there!

There’s a UK Telegraph article published today entitled, “The big fat calorie countiing con.”  The article claims that calorie counting is “scientifically flawed”, and that “it could be doing more harm than good.”  The article then links to an OPINION paper and calls it “research.”  The paper, entitled “How calorie-focused thinking about obesity and related diseases may mislead and harm public health.  An alternative”, as well as the Telegraph article linking to it, create a giant strawman.

The strawman is that the concept of calorie counting is flawed because it ignores food quality and treats all food calories the same.  This is utter nonsense.  Calorie counting is simply an awareness tool, no different from regularly stepping on the scale to check your body weight.  Both are types of self-monitoring.  Now, just because the scale can’t tell you how much fat or muscle you’re losing doesn’t mean it’s not useful.  Likewise, just because calorie counting can’t tell you the quality of those calories doesn’t mean it’s not useful.  You can still overeat on “quality” calories and not reach your weight loss goals.  Ultimately, calories still matter whether you like to believe it or not.

The article brings up the usual “a calorie is a calorie” strawman as well.  Technically, yes, a calorie is a calorie in terms of energy.  This doesn’t mean they will have identical impacts on your body; no one that I know who considers calories important takes this position.  This is why it’s a strawman.  No one is saying that eating 1000 calories of jelly beans is the same as eating 1000 calories of steak.  Of utmost importance is satiety; for example, protein calories are more satiating than carbohydrate or fat calories in general, allowing you to eat less.  In this sense, the quality matters.  But if you’re trying lose weight and fat, ultimately you still need to eat less calories than you expend.  In this sense, calorie counting simply becomes an awareness tool to help you achieve that goal.

The research is very clear on calorie counting, and it demonstrates that calorie counting is beneficial.  In one study, people who frequently recorded their food intake lost over twice as much weight as people who infrequently recorded their food intake.  Another study showed that self monitoring of food intake was positively associated with weight loss success, and not monitoring at all was negatively associated with weight change.

This doesn’t mean you have to count calories to be successful.  But the research shows that you are more likely to be successful if you do.  Again, it’s just an awareness tool.  There is no credible scientific data that I am aware of to show that using this awareness tool is misleading or harmful.  What is misleading or harmful is when people create strawmen over what calorie counting actually means.

Normally I don’t endorse products, but Sol Orwell and my other evidence-based friends at Examine.com have put together “Supplement Stack Guides”.  If you are interested in dietary supplements that actually have science to support them, these guides are for you.  The guides are organized by goal.  For example, if your goal is muscle gain and exercise performance, there is a specific guide for which supplements work together to help you reach your goals.  Only supplements with solid scientific research behind them are supported  These guides are truly ACTIONABLE lists of supplements.

If you’re interested in checking out the stack guides, click here.  Note that I am an affiliate for Examine.com and receive a small commission for orders placed through my site.  However, anyone who knows my background or my past article/posting history knows I would never recommend anything unless the evidence behind it is rock solid.

Dear Weightology Weekly Subscriber,

In what has been a difficult decision, I have decided to not continue with Weightology Weekly.  With the recent major changes in my life, it has become too difficult to find the time to write articles on a weekly or even monthly basis.  When I started Weightology Weekly back in 2010, my goal was to deliver evidence-based, scientifically accurate information in the field of weight loss, nutrition, and fitness.  I feel that I have successfully achieved that goal.  However, as a paying subscriber, you deserve my full attention and ability to deliver articles on time, something which I feel that I can no longer do.  Therefore, there will be no more future issues of Weightology Weekly.  I have canceled all automatic Paypal payments, so there is nothing that you need to do on your end.

I appreciate everyone that has continued to be a subscriber of my service and who has found it of value.  Therefore, anyone who was a current paid subscriber as of June 22, 2014, will continue to have indefinite access to all past members-only content of Weightology Weekly.  For anyone who was an annual subscriber, I will refund you the remaining months that you had on your subscription on a pro-rated basis.  Please be patient with me on this as it will take me some time to go through each annual subscriber and determine how much needs to be refunded.

I want to thank all of you for being Weightology Weekly subscribers.  I hope you have found the information that I have provided extremely useful in your own endeavors or that of your clients.  I will continue to be available to all my subscribers via email or via the comment sections on the articles.



P.S.  For anyone who is not a currently paid subscriber and is interested in access to the archives, I will be offering access to all past content for a one-time fee which is yet to be determined.  I will eventually update the subscription page when this option is ready.
