38m fasting 16:8 from 8pm to 12pm
I’m very tired until I break my fast and actually have carbs, yesterday I broke fasting on ground beef and eggs only, I was falling asleep at my desk and could smell acid in my breath, had some chips and boom! I’m awake
Been going on for almost a week now
Notes:
I’m trying to lose weight
I am not diabetic
I eat around 1300 calories a day (breakfast eggs and beef, dinner protein chicken or beef and 200gm rice)
Edit: I work out 6 days a week, heavy lifting, HIIT, followed by 1hr of cardio all fasted starting 5 am

I’m not sure the carbs woke you up, but the salt in the chips might have. Make sure you’re getting enough salt! A little pinch does it for me when I start feeling a little off or sleepy.
I’m not in ketosis, but reducing carbs is definitely helpful during IF. My cravings went way down. So my take is that you need to eat enough and don’t reduce too much every day, especially if you have a rigorous workout routine.
