The Problem with Constant Eating Habits
A significant number of non-shift workers in the US eat over a 15-hour period each day, compared to less than 10% who eat in under a 12-hour window. This constant eating pattern is abnormal and differs greatly from how humans have historically lived. Eating for extended periods keeps the body in a fed state, with high insulin levels signaling the body to store excess calories. On the other hand, fasting allows insulin levels to decrease, prompting the body to use stored calories. By reducing the eating window to around 8 to 10 hours per day, individuals can easily incorporate intermittent fasting into their routine, which promotes a more balanced and natural relationship with food.
