Understanding Intermittent Fasting: More Than Meal Timing

Intermittent fasting is an eating plant that alternates between period of contritary fasting and eating. It is nott a diet in thee conventional sense - there e is no redirecbed list of foods to eat or avoid - but rather a schedule that leverages the body 's evolutionary adaptations to period with out food. Several well- studied procours existt:
