I've been on a new diet schedule this summer. Whenever possible, I am going eight hours between meals. In practice, this means I eat twice per day.
At these meals, I eat a lot- probably more than 99% of people eat at any one sitting. But after that, I stop. Once eight hours go by, I'm open to doing the same thing again.
Every once in a while, I'll skip a meal and just eat once per day. Sometimes I make up for it by eating more during the sole meal. At other times, I eat more the day before or the day after.
My logic is not scientific but I think there is something to it. The body clearly thrives when periods of rest alternate with periods of activity. Since the exact way this general truth applies to metabolism remains poorly understood, I'll settle for the simple 'eight hour fast' approach. Who knows? Maybe I'll benefit from allowing my digestive system to rest twice a day for over eight hours.
A machine kept running without rest eventually burns out. The body might not work in exactly the same way. But what's the argument for doing otherwise?
