Thanks for the info, I found 2 weeks ago, that I have a hard time of burning fats... versus carbs during training or maybe something else was going on (there was has been a change
in my workouts from morning to
evening too)... but I started eating 75g or so of carbs at night (with same training intensity,, mostly aerobic with 2 days of «speed») the following week my energy levels were back to normal... not sure I do so well
in ketogenic state or perhaps I wasn't as balanced as I should have been (carb, protein, fat) or my body just isn't acclimitized to those things yet (ketosis)... working on it though...
