Omad is a form of intermittent fasting that can also be referred to as a 23:1. This means you are fasting for 23 hours and eating within one hour. You would not be consuming any caloric beverages or food outside of your one-hour eating time frame.
With the Omad diet, you can choose to eat whatever meal you choose with no restrictions inside of your eating window. However, it will be better for your long-term overall health, to choose a healthy balanced plate containing the food groups.
