Tag: Early fasting

According to a study conducted by Johns Hopkins neuroscientist Mark Mattson, our bodies evolved to go long periods without eating, but modern eating patterns with frequent snacking disrupt our natural metabolic cycles. The question is, does it matter when these fasting periods occur for optimal results?

Approximately 4–6 hours after your last meal, your body completes its primary digestion phase and begins a significant metabolic transition. Understanding exactly what happens to your body when you fast for 4 hours is key to appreciating the subtle but important internal shifts that occur long before deep ketosis begins.
