That's a pretty low carb intake. I do a good bit of cardio and will cramp really bad when I'm under 50g of carbs.

I try to only get carbs from fruit, milk, and potatoes to keep the carbs clean.

My common sources of carbs are potatoes (microwaved, then chilled in the fridge, consumed cold), stone fruits, citrus, apples, berries, avocado, peanut butter, peppers, tomatoes, yogurt, fermented vegetables.

I dont get cramps but I do supplement magnesium glycinate or taurate daily you may want to look into that if you havent.

Ive fasted for multiple days and done cardio each day w/ no cramps, just sharing my experience.
