3500 Calories To Lose A Pound – Myth?

Well, it’s not that straightforward (of course), but 3,500 calories does equal a pound of fat so it’s a good rule of thumb (in my non-clinical opinion).

So, to figure out when this does or doesn’t work, I looked at the this article in the Journal of Obesity which was very difficult to understand, but here’s a discussion on MyFitnessPal that discusses it in something closer to plain language.  You can also see this article in the NY Times about de-bunking this myth.

So, if it’s wrong, why use it as a rule of thumb?  IMHO  I believe it gives you some numbers to track just understand that it’s not a perfect correlation.  But, if you take in less calories than you burn and focus on creating a deficit, then you’ll be doing the right things – being active and watching what you eat.  Of course, you can go work with a Registered Dietician to help you actually understand and refine your plan to address the gap between this assumption and reality.
