Have you actually tried working out in a fasted state? I find that I get better performance.
Glycogen isn't depleted as quickly as you think, and blood sugar levels are actually more stable in a state of ketosis when your body is manufacturing its own glucose.
>You don't need intermittent fasting to be healthy.
Semantics, but I would say you do if 'intermittent fasting' just means periods of respite between meals so you're not constantly in a 'fed' state. It's only relatively recent in human history that we are even able to be constantly eating.
>Keep your fat, protein, and simple carb levels within reasonable limits for your age, height and sex.
You say this, but experts have all sorts of contradictory recommendations for what are 'reasonable' macro limits.
