WHAT IS OMAD? OMAD is an acronym that stands for One Meal A Day. It's a type of Intermittent Fasting (IF) where you eat all your food for the day within a specific 'eating window.' What does that mean? Well, technically, you don't have to eat just one meal in order to follow the OMAD 'rules' or guidelines correctly. Most people following this dietary protocol go without food or caloric beverages for a certain period of time, then break their fast by eating only during certain hours. There are many different variations of this Intermittent Fasting plan, and you can choose to start with a shorter 'eating window' before working up to longer and longer periods of fasting.
