This guy used to run a successful fitness boot camp business. But realised that as a fitness solution it was wrong. He conducted a series of experiments on himself and disproved the CICO model as irrelevant when it comes to food and public health. “Sam rather impressively chose to make himself temporarily sick to prove all calories are not created equal – they differ in nutritional value and biochemical impact. Hear how the former fitness trainer and entrepreneur scoffed nearly 6,000 calories a day for 21 days at a stretch to test three dietary regimes: real food, fake food and vegan.” https://www.susanflory.com/sam-feltham/
