Why do OMAD if i am not going to lose weight

My main goal is to lose weight by doing OMAD. However, there isn't convincing evidence to suggest the OMAD diet will lead to any more overall weight loss than a conventional calorie cutting. I am not talking about other potential benefits but just weight loss. Is this true. OMAD will only lead to weight loss if you eat in a calorie deficit? Then what is the point if my goal is to only lose weight. Why starve myself for 23 hours
