Absolutely no! Although I eat once a day at times, but I can never partake in the practice of doing so on daily basis. I can seem to wrap my head around it, maybe because I don't really need it. I have a perfect shape that anybody could ever wish to have. My exercise routine has always been part and parcel of me ever since I was kid.
And since I attained my adulthood age, I have never for once taken my foot of the pedal in keeping up with my workout plans and diet programs. Interestingly, I have absolute control of what I eat, it's not that somebody is dictating for me what to eat. And if I want to fast, I usually do so voluntarily, especially if I don't have the appetite to eat.
However, for those individuals that think they need OMAD for them to stay fit and healthy, let them keep it up. But my advise for them is that, there can never be substitute for exercise and healthy meals as ways of stay fit and healthy.
