I was listening to Robb Wolf the other day via one of his Podcasts, and the thing I had to agree with him most is....
Until you have everything else dialed in, IF should be the last thing you do for health and wellness.
You want to bodybuild to get big. So you need to eat like a freaking hippo. Except do it the Paleo way (get rid of that rice stuff!). Then every once in a while on a rest day, skip breakfast and lunch then gorge your dinner like an ancient man just killing his meal for the day.
To lift big you gotta be big, and not eating is not going to make you big.
