I haven't noticed any. I've been intermittent fasting for about two years with 16 hours no eating 8 hours to eat. Occasionally a 24 hour fast. Usually the most intense hunger pangs occur when I have eaten a lot of carbs the day prior. I do weight training and running. Usually after a workout I feel like the cravings I do have are more manageable. You do need to be careful though. I wouldn't recommend doing any weight training if you're doing more than a 24 hour fast and if you are weight training while fasting make sure you have a spotter. At least at first.
