I've read and heard that ketones actually pack more of a punch in the energy department than gluclose does. It's just your body producing it is the problem and challenge.
I'm not pro keto or against it, but how long did you try it? As your body adjusts it's said that it can take literally weeks not even a couple of months to your body to fully adapt to producing ketones and getting itself off glucose. If you felt really bad especially in the beginning it probably has to do with that adjustment and if you still felt pretty bad weeks after it might have to do with your fat intake. You have to have at least around 75% fat intake so your body can use that as energy.
I tried it for almost a week and just couldn't handle the adjustment. My work requires a lot of physical labor and I just wasn't personally ready to feel sluggish like I was.
In the end what I have personally done is greatly reduce my sugar intake, Especially un-needed sugar. I try to stay away from bread and pasta as much as I can, especially no soda or sugary foods and junk. Just stick to sugar in fruits and veggies (no corn though).
In the end, I don't doubt intermediate fasting is healthy, and I don't doubt us eating as much sugar as we do is unhealthy because it defensively isn't. There was a recent study done that showed back in the 40s the average American had 15g of sugar daily, now that's up to 75g+ at least. One can of Pepsi or Mt. Dew covers almost all of that.
