if you stay in the region of 30-70 carbs, will you make it worse by being too high for ketosis, but too low to derive the carbs energy?

say you want to push from feeling 100% to 110% in energy, cognitive clarity, well being, etc. what would the optimal level of carb intake be?

should you be as low as possible? should you be in ketosis? should you have high paleo carbs, without fruit?

Well you might consider it a "sweet spot" in which you are using ketones, glycogen and fat at the same time.

I'm a big fan of ketosis, if you have a specific medical or metabolic need to use it, but I think that the 50 - 160g range is probably the best. You aren't overfilling you liver with glycogen, but you're eating enough to fuel your muscles.

That's what I'd be doing if I wasn't diabetic.

Yeah, quite individual. I think its Robb Wolf that has the pyramid....you can't optimize for everything. You have to pick one or a combo of "health, athleticism, or logevity". Then you have a framework to start working with.

So to answer you have to ask yourself what your goals are. What are you currently doing to achieve the goals. And what have you tried that has or has not worked for you already.

It's not an all-or-nothing situation. You have beta-oxidation of fat as another way to produce energy. The key is to maintain metabolic flexibility to switch among the available fuel sources.

It definitely takes some experimentation to "dial in" what is optimal to achieve your goals. For me: I wanted just enough glycogen replenishment to fuel the next short intense workout and burn fat in the meantime. The amounts you described above are typically in the range of what I consume post workout. I typically eat very low carb on non workout days (basically a CKD) and it has been very successful. Set your goals, do your experiments, record the results, and dial it in!

I have done fine on 50, 60, 70, 80, 90, 100 up to 150 or so.

I dont really notice much difference, so I just make sure I am not guzzling/scoffing carbs left right and centre and dont think about it otherwise.

No real difference in energy, or clarity for me. I am not super active yet though.

Theres no real issue with fruit IMO. Unless your eating high sugar fruit all day, or drinking juices. Well, people vary, depending on the state of their health, but I dont find fruit to be bad unless its juices or lots and lots of high sugar stuff (excepting low sugar cranberry juice)

There's no "right" answer to this question, everyone functions differently depending on what they eat. That being said, once you become efficient at burning fat for fuel, your body will be able to switch between burning ketones and glucose as needed. The only thing you can do is experiment and see what works best for you.
