This one has been gnawing at the back of my hand for quite some time, but I let it go because I thought it was plainly obvious why GOMAD is a terrible idea, obviously this isn't the case. So I will explain what the GOMAD is and why it is terrible, in the same sort of format they use on the stronglifts site to promote it.
What is GOMAD?
GOMAD is the acronym for "Gallon Of Milk A Day" diet. The idea is to consume a gallon of milk per day, ON TOP of what you would eat to reach maintenance, adding around 2500 calories to w/e your daily diet is, usually coming out at around 4000, 5000 calories for most people.
Benefits of GOMAD diet
"Weight Gain. 25lbs weight gain during the 1st month is common on GOMAD." - This is true. 25lbs of fat and water retention that is.
"Strength Gain. The protein & fat content in whole milk helps muscle & strength gains. The weight gain also helps strength gains." - What? Caloric surplus combined with a solid strength program will produce strength gains?? Holy shit someone notify the press. This is a fucking no brainer.
"Easy. Liquid food is easier to get in than solid food and digests faster. Milk also needs zero preparation and is easy to take with you." - This is a fair point.
"Cheap. 1 gallon whole milk contains 2400kcal, 200g carbs, 120g fat, 120g protein and lots of vitamins & minerals for a relative low price." - Also fair point.
"Natural. Some say that GOMAD works even better than steroids with beginners who want to gain weight fast." - This is gigantic load of SHIT. Nobody who actually knows what the fuck they are talking about would even dare contend that milk produces faster muscular gains than AAS. The mere fact that they are even trying to compare milk to something that changes your fucking HORMONES and chemistry is ridiculous.
"Permanent Gains. GOMAD teaches you to get more calories in, the key to weight gain. You'll never be skinny again." - Yeah but you'll also look like a sack of shit.
So why is GOMAD fucking retarded?
You cannot force feed your body into packing on more muscle. Contrary to the popular /fit/ notion, a larger caloric surplus does not necessarily mean more muscle. Creating muscle and laying new neural pathways is a metabolically taxing process that takes time. That's why trying to rush a bulk is retarded and will only end with you getting fat. I don't give a fuck what these retards say, you cannot, CANNOT gain 25lbs of muscle in a month without anabolic steroids, and even then, good luck.
Hell they even state right there that your bodyfat % will increase 3-4% per month. THIS IS NOT FUCKING HEALTHY AT ALL.
Consuming that much milk on such a consistent basis could wind up making you lactose intolerant, unless of course you have access to raw milk (good luck) which has enzymes (lactase) that are destroyed in the heat treating process. Then there are several other problems from this much milk consumption. Many people doing GOMAD will comment on the bacne/acne problems that arise, these fucking idiots claim it is from increased testosterone levels. Sorry but that is fucking dumb and more broscience shit. Go get some blood work done one week, and then do GOMAD for 2 weeks and get retested, I guarantee your testosterone levels will not have increased by any notable amount. The acne is from the huge milk consumption and rapidly increasing bodyfat storage.
Guys end up heavier, for sure. But this isn't quality weight. Majority of your gains from GOMAD, unless you had some fucking amazing genetics and a shitton of AAS, would be fat and water retention. The assumption is that you do GOMAD and then "just cut bro, you will be better off for it". But let's do a little experiment:
Do GOMAD for two month -> gain up to MAYBE 4lbs of dry muscle, gain 3-4% bodyfat -> spend next 2-4 months cutting depending on how committed and driven you can be
Just do a regular sensible bulk for two months -> gain up to 4lbs of dry muscle, gain no significant amount of bodyfat/maybe even get leaner -> spend next 2-4 months getting bigger and possibly leaner
I think it's fucking obvious which choice produces more sensible results.
The only time I would EVER recommend someone does GOMAD is if they are someone with a huge energy turnover, i.e like a professional athlete who is in the gym for like 8 hours a day, that would actually justify a caloric surplus of 2500 cals.
As a conclusion, I feel I need to state I'm not opposed to teaching skinny motherfuckers that they need to eat a lot to get bigger. However GOMAD is excessive and retarded, fin.
