John is one of the founders and owners of the Irish Strength Institute, and has recently completed a PhD in weight cutting for MMA athletes. He discusses how weight cutting works, the physiological and performance effects, the differences between weight cuts and actual weight loss, and he explains his approach and ethos when it comes to helping his clients achieve their health and performance goals, with some great insights on nutrition, training, longevity and more.

A great conversation with a hugely knowledgeable guy.
