That can be the same, but for most people would probably not be. IF means having a fast of about ~16 hours, giving you an eating window of 8 hours a day. So if you skip breakfast and eat lunch at 11, your last piece of food should be around 19. Most people when they don't eat breakfast, though, will probably have a small snack with their morning coffee, or even just some sugar in it (thus starting the window). And might also have some more food late in the evening a few hours after dinner. Most people will also never be on board when one touts it as "skipping breakfast", as for them that's a negative experience. For me, never eating breakfast is ok, as my body is used to it. But for those used to eating it, the days they don't get their breakfast equals a bad morning. Either because of the circumstances leading to them not getting to eat (overslept, stressful morning), or in combination with an unusual feeling of hungriness and tiredness.
