Ep. #832: Dr. Bill Campbell on Re-Evaluating the Science of Rapid Fat Loss

In this podcast, I chat with scientist and friend Dr. Bill Campbell about a new study on rapid fat loss that came out of his lab.

In case you’re not familiar with Dr. Campbell, he’s a professor of Exercise Science and the Director of the Performance & Physique Enhancement Laboratory at the University of South Florida, who’s also published more than 150 scientific papers.

In other words, Dr. Campbell is busy conducting studies that test questions many of us have with answers we all want to know.

His latest study on rapid fat loss is a prime example. While most of us want to strip away fat as quickly as possible, we also don’t want to lose our hard-earned muscle in the process. So the question is, how aggressive should we be during a cutting phase to maximize our fat loss benefits and minimize any negative consequences of being in a deficit.

And that’s exactly what Dr. Campbell’s latest study looked at and the results actually changed his mind about rapid fat loss. In this episode, Dr. Campbell describes the study, the results, practical tips you can implement to lose fat as quickly as possible, and what future studies on this topic might look like.

So, if you want to learn about the latest research on losing fat fast without shriveling into an atrophied raisin of your former self, don’t miss this episode! Press play and let me know what you think.
