Yes they do. People often confuse the concept of “energy balance” with their own interpretation of the somewhat amorphous acronym “CICO”. They are not even remotely the same thing.
Here is the difference. Many scientist and researchers have claimed that Calories In vs Calories Out is a vast oversimplification of a complex, hormonally controlled, and non-static metabolic equation. No scientist or researcher has ever claimed that energy balance does not play an important role in fat loss. Let’s make a list of people who acknowledge that energy balance plays a role:
- Dr. Phinney
- Dr. Volek
- Dr. Fung
- Dr. Westman
- Lyle McDonald
- Chris Masterjohn
- Mark Sisson
I would keep listing names but then I realized that there isn’t a single scientist, or a single study that I’ve ever read that has ever claimed that energy balance didn’t play a role in fat loss, so it’s pointless to list the ones that do. I’ve read many people argue that hormones are as important, and many who say they’re more important, but I’ve never read anything that said energy balance was irrelevant.
