One follower commented on her photo, "what'z the secret????" Dianne simply replied with, "omad [heart emoji]" which stands for the "One Meal A Day" diet. It meant that Dianne had been eating one meal a day only to achieve her slender figure.

The One Meal A Day or OMAD will help you target calorie deficit because you only eat one meal a day. But, dieticians remind you that you have to be mindful of reaching your daily nutritional requirements for vitamins and minerals. This is hard to achieve, especially when it's a challenge to reach your target protein intake in one sitting.
