What is OMAD?

The one meal a day diet, or OMAD, is a way of eating where a person has only one meal during a 24-hour period. Instead of having multiple small meals or snacks throughout the day, individuals who follow OMAD choose to consume all their daily calories in one sitting.

They will then fast for the rest of the day, abstaining from eating until the next scheduled meal. The meal consumed during OMAD is often substantial and nutrient-rich, aiming to provide the necessary sustenance for the entire day. It’s important to note that OMAD requires careful consideration of nutritional needs and may not be suitable for everyone.
