I have a ton of experience with this diet. When I started reading about it, I was 180 lbs. and struggling to put on weight. I thought I ate "a ton of food", just like everyone else. I was willing to try anything to stay natty, so I started doing it. Within a month and a half, I was 200 pounds, and my the numbers were just flying up, I felt like a monster. This was two years ago. Since then, I have gone from a half gallon to a gallon a day and back again, but recently I started to feel like a diabetic (lethargy, no focus, ton of sugar in milk) after 6+ months of never missing a day of a gallon, so just be careful. Eat whatever you can while on this diet, it will be hard, but you can do it. Just do it for two months, then stop. You will maintain the muscle if you keep you cals up with quality food. FWIW, this is coming from a guy who was 155 lbs. and skinny his whole life, who could never seem to gain weight. I'm sitting at 220 with 15% BF, never touched a PH or gear, not as lean as I would like, but I'm not a 155lb. weakling anymore. Trust me, it works, and it is cheap, and natural. The reason it works is it is easy, no magic here. If you could get the same cals with clean foods down, you would get the same or better results. Problem is, few actually can 7 days a week. This diet makes it hard to cheat. No matter what you are getting 2K cals a day. Get used to people making fun of you for carrying milk everywhere, but they won't be laughing in 2 months.
