Fructose, Knee Sleeves, Weight Loss Variability, and James Krieger

Greg kicks off the episode with an insincere but legally valid apology, followed by some impressive feats of strength. Then, Eric covers a brand new fructose study in a new segment called “Hot Off the Presses,” and Greg shares some new research related to knee sleeves. After that, Eric has a big Research Roundup segment about why some people struggle to lose weight, and Greg provides some tips to help you perfect your turkey roasting. Finally, Greg and Eric interview James Krieger about topics including the insulin hypothesis, non-exercise activity thermogenesis, why you should or shouldn’t get your body composition measured, and more.
