does a high fat diet(ketones) makes you able to fast more efficiently and longer compared to an individual who uses glucose for energy?

I said "in an healthy individual". Not in somebody having diabetes.

That's not true. People can have high insulin and low blood sugar. The correlation coefficent is not equal to 1.

low blood glucose does not mean low insulin.

Also, when you have constantly low blood glucose hence in an healthy individual low insulin levels, lipolysis won't be inhibited so the body will use the energy that's stored in his adipose tissue and thus will produce ketones, whenever he is deficient in energy.

crightfunnylol talks about people driving primarily on ketones or glucose. Somebody using both energy sources in nearly equal amounts will have an easier time to fast than the glucose-user, but a harder time compared to the keto-user.

You don't have to be either high fat or high carb- there is a middle ground that you seem to be forgetting about. Also, I don't how accurate your last sentence is. I think it's more accurately that "the effectively low carb person can..." ELC meaning carbs in balance with exercise.

You don't have to be high fat or high carbs. There is middle ground that nearly every one seems to be forgetting about.

It is definitely easier for a high-fat-eater to fast, as he is used to having low blood glucose levels, whereas the high-carb person relies on carbs to maintain his well-being. The high-fat-person can make the energy from his fat tissue faster available.

From my own experience I'm never really hungry after being on a ketogenic diet. In that's sense it's easier but if it's more efficient I'm not sure. It depends on what you mean by 'efficient'.

One of the functions of ketones bodies is to burn fat inefficiently so that we last longer when food is scarce. So, yes, if you are in ketosis you will be able to go for longer periods without food, as that's why they're produced. Ketones are a survival protection mechanism designed to keep you alive for longer.

Anorexics enter ketosis without eating a high fat diet. This happens whenever your body turns into survival starvation mode.
