if you want to gain alot of fat, by consuming totally useless calories, then have fun drinking your gallon of Milk :think:
You do realize that in order to build muscle you need calories, correct?
You also do realize that most people who end up joining this GOMAD are the very hard gainers, which lack sufficient nutrition as they don't consume enough calories to be over their maintenance level. Also, finally, usually these are the individuals who are not experts in nutrition and therefore do not have extensive knowledge on how to bulk / take in enough calories.
With all that in mind, how is it far fetched to see how 2400 extra calories a day, on a very decent macro breakdown between Carbs / Protein / Fat is something extremely ludicrous of an approach? You're getting extra calories, easy to take around with you, you get your macros, you make sure you're not burning more than you're taking and you work out hard in order to pack on muscle.
And lastly, I was unaware that milk calories are somehow "useless". When did milk get in the same boat of alcohol as useless calories?
