intermittent fasting?

Whats up Marc!?My name is Ran. I love and appreciate what you do.  My question is in your experience how effective is intermittent fasting, and also how important and what role does the caloric and macro intake play? , Im a 31 year old natural lifter in pretty decent condition but Im hitting a standstill in the fat loss department even though Im relatively lean. Ive been fasting for the past 3 days, obviously too soon to tell but Im curious as to what Im in store for.( I have a potential photoshoot in the next 10 days) I also understand that the leaner you are the more difficult fat loss can be. If you have time you can check me out on instagram @the__nature__boy just to see where Im coming from with my physique and if this can be benificial to me. Any advice is appreciated! Once again I love what you do, keep it up and God Bless.
