Good tools to resuscitate the capability to oxidize fat effectively. And magically it also tends to correct the chronic metabolic dysregulation that prevents effective glucose oxidation, but the mechanism is still open for debate and controversial.
I absolutely don't subscribe to the process of eating 4 times per day and snacking in between to keep blood sugar steady and high. Digestion is stressful so 2 meals per day at most for a healthy person with normal capacity to store glycogen. This naturally results in slightly elevated ketones before the meals, which keeps the body keto/fat adapted.
that's what's funny when debating with narrow minded individuals. Just like lactose tolerance is a thing, high carb tolerance is perfectly natural.

If you're a (T,T) homozygote like I am, you'll be adapted to IF and such. Be aware of your own biases and don't tell people who have different genotypes that they should embrace your way of life - which is also valid whenever someone tells me I shouldn't be fasting or rather, massively undereating for 18 hours a day (I still snack on berries for breakfast and oysters at night)
