Given that its pretty easy to go for a few days without eating, once you let your body adjust to it, this sounds plausible to me. Besides, on days when I’m not working, I can easily go until 4 or 5pm before eating (and then only eat once more before bed).
I've been doing that for more than five years. Not five summers: five whole years. I only very rarely eat at the office. I guarantee that your body will adjust after a little. In fact, you'll probably be surprised about how little it takes to get accustomed.
In fact, I think this is why intermittent fasting is somewhat easy to adopt: it's surprisingly fast to adapt your body to a different meal schedule, as long as you're eating as much as you need.
