You say you’ve been eating keto ‘nearly a year’ and lately experience ‘low energy’, my first question is: what changed? New job? More physically demanding tasks? More time at the gym? Changed how much and what specifically you’re eating? Or have you always felt like you do now?
As @mtncntrykid notes above, you’re eating a lot of carbs. Maybe too many for you. I suggest you go directly to sub-20 grams of carbs per day to see if that helps. Keto is basically carb restriction. Just cut the carbs and replace the energy you used to get from carbs with fat. That’s it. It’s not fancy and it’s not rocket science. Stay in ketosis as consistently as possible and fat adaptation will result. If not, then not so much. Once you’re not eating sufficient carbs to fuel your activities and not extracting energy from fat efficiently, you’re going to feel just like you describe.
Also, you have to eat enough for your level of activity. What you’ve described is a very physically demanding lifestyle. Your total energy intake may be sufficient if you were better fat adapted and extracting all the energy available in fats and ketones. Until then, you probably have to eat more to get enough not to drop dead at the end of each day. Take it slowly, a hundred calories per week or two.
Keto is a metabolic normalization process which includes weight normalization. Lots of good things happen in ketosis that otherwise don’t. But you have to remain consistently in ketosis otherwise you’re knocking yourself out for little or nothing.
