In this episode, Monica breaks down what the research actually shows: • What the five-day protocol involves, including the calorie targets and why it's deliberately low in protein • What "fasting mimicking" means, and which effects of a multi-day fast it's trying to reproduce • The 2017 trial in 100 healthy adults, where participants lost about five and a half pounds over three months but saw no change in blood sugar, cholesterol, blood pressure, or inflammation • Why the subgroup findings are interesting and why they aren't proof • The 12-month trial in people with type 2 diabetes, where 40% reduced their diabetes medication compared with 5% in usual care • What the cancer research has shown in mice, what it hasn't
