Here's another thought:
What about natural sweeteners like raw honey? I'm halfway through the book (well past the "science" and well into the "meal plans") and he has yet to even mention it.

Honey was probably the most common sweetener throughout much of history -- though rarely consumed as it's so dangerous to get at

So would eating honey-sweetened desserts once in a blue moon actually be so bad?
(And, can you tell I am trying to come up with a way to eat dessert )
