In his latest podcast, GP, Author and TV Presenter, Dr Rangan Chatterjee talks to world-leading researcher Professor Valter Longo about eating well for longevity.
Professor Longo shares his views on diet and nutrition, discussing high protein diets, ketogenic diets and low carb diets; communities in where people live longest, like in Sardinia and Okinawa; and the potential benefits of fasting and restricting your eating window to 12 hours.
He says that the ketogenic diet, for example, is not designed for longevity, warning that most people would see it as a high-fat, high-protein and low-carbohydrate diet, which leads to a higher risk of earlier death, cancer and cardiovascular disease. He also points out that the communities of people who live longest do not eat these kind of diets and that carbs should actually make up around 60% of your diet, with fat accounting for 30% and the rest, including protein, making up 10%. However, like all food groups, there are good and bad carbohydrates. He says legumes and vegetables are the best sources of carbohydrates.
