The above routine looks interesting. I find it hard to imagine that I'm not eating enough. 4000 calories is the minimum I get daily, often closer to 4500. It would be hard to add more without resorting to sugary foods, which I usually avoid. I'm sure I would make progress on 531, but I'm trying to reach my goals before slowing down. I've read about many who have gotten much further than me on SL, so I'm frustrated.
Where I can look over the BIG program mentioned?
