If you have some time to spare – 1:17:29, to be precise – you might be interested in this presentation on YouTube: ‘An Advantaged Metabolic State: Human Performance, Resilience & Health’. It’s by Peter Attia, a medical doctor who’s been ‘obsessively reading everything on the science of nutrition’. He also has a blog, The Eating Academy, in which he gets pretty technical, but the video is comparatively accessible. Peter shares his path from ‘fit but fat and metabolically deranged’ to ‘fit, lean, and metabolically dialed in’. He shares his experience of the keto diet – both first-hand and in others.
