OMAD may not be a sure bet in weight loss but it can help in ways, including;
Can increase metabolism
A case study of prediabetes and obesity individuals indicated that they improved their blood sugar amounts after eating for six hours and later fasted for 18 hours. The diet may not have been OMAD, but this kind of restricted eating can be linked to heightened metabolism. However, more research to determine if the same effect will happen when eating one meal per day is required.
Can burn fat
Studies indicate that participants who used OMAD had less body fat with a minimal weight loss. Even intermittent fasting is evident in helping lose weight effectively; around 10 pounds in 10 weeks.
Morning meals only in a day can reduce body weight
Did you know that fasting overnight has proven to help lose more weight compared to those eating dinner? Even eating larger meals in the morning has shown better outcome in weight loss than more for dinner. Therefore, while OMAD is not specific on which single meal to choose, I highly recommend going for breakfast for better weight loss results.
