Carbs u need to bump up. Especially on training days. U will burn out sooner or later with such low carb.

Cardio - i have good experience training fasted when im on IF diet. Wake up 1/2 hour earlier. One cup of black coffee and then go walk for 30 -45 mins. (Not jog, current bf and weight i think u will hurt ur knee more than the benefits).

Prolonged low carb ie less than 100g will send yr metabolic rate to decrease. Not a good thing. I would rather do this, low carb on non training day n start loading up carb to 1g/lb on training days. Its like carb cycling. More when u train, less when yr not. All the best!!!

Not sure u know why you should stop IF besides getting advice from pro. I usually do my own research and weighs the benefit and cons. Besides, adherence to a nutrition or training regime is always will be the foundation of success. Your call.

Bro is a gal btw lol
