Factors affecting fasting effectiveness?

Factors affecting the effectiveness of fasting include the transition from a fed state to a fasted state. Andrew Huberman explains that after consuming food, the body remains in a metabolic state where glucose and insulin levels are elevated, which does not truly reflect a fasted state. To accelerate the transition from a fed to a fasted state, engaging in light activities such as a 20-30 minute walk after a meal can be beneficial. This helps in clearing glucose from the system faster and increases gastric emptying time, allowing the body to enter a fasted state sooner 1.
