It sounds interesting. Only eating once and at night. But doesn't that make your metabolism become extra slow so you don't burn fat or have adequate energy during the day? And what about supplements and bone health? Are these important to take only once a day as well?

I've never only eaten one meal a day, but I definitely eat way more on a high fat low carb diet than on the high carb low fat diet. Perhaps if you eat when you're hungry you'll have a higher bone density, more strength, and the ability to think more clearly if you eat whenever you're hungry (ie once or twice a day). I usually get hungry three times a day, so I eat three times a day. I think ultimately your metabolism adjusts to how much you eat, if its something like high fat low carb.
