Does anyone have any experience or thoughts about the low-carb/high-fat diet put forward by Prof Tim Noakes, Grant Schofield etc? One of the presenters of Marathon Talk has been talking about it for ages and I've been intrigued and some of the online info looks interesting. This year I'm determined to get a half-marathon PR despite my advancing years and I need to lose about half a stone. I'm more bothered about fuelling well to be honest, but weight-loss will be required for a while. Any thoughts?
