Yeah, with one you risk your metabolism slowing down. In terms of fat burning, there shouldn't be that much difference. There is only so much fat your body can convert into energy at any one time, if you go over this you're in trouble. > 5.

You don't need to run out of fat, you just need to run out of accessible fat. You have an upper limit to how much you can instantly access, the process takes time. That's why people carb feed just before exercise to increase their workout performance, otherwise you'll literally run out of energy and crash. > 6. Rounding error.

It of course depends per person, but metabolic slowdown is a real concern. To me it sounds like this person switches from fasting to OMAD (intermittent fasting) + VLCD, which is still unsustainable over long periods but is much more sustainable than a water-based diet.
