The infamous "GOMAD" approach to gaining weight has been around for about a hundred years now, with pioneers such as Milo Steinborn and Joseph Curtis (JC) Hise leading the charge on it in it's infancy and other great men of strength such as Paul Anderson and Doug Hepburn continuing it's momentum. It's been written about by authors such as John McCallum and Randall Strossen, and even advocated by more modern types such as Chase Karnes and Matt Reynolds. HOWEVER, as is often the case with great ideas, the telephone game (I'm dating myself there I'm such: do kids call it the textmessage game now?) has been in effect, and much of the truth behind this method has been lost. I figure it's worth having a discussion on the subject.
I did the gallon of milk a day approach to gaining back in 2006, while I was in college and on a meal plan, which definitely made things easier. I paired it with the "Super Squats" program, as that is where the idea was heavily emphasized. You can read about that program here.
In the 6 weeks I drank the gallon of milk a day and ran the program, I also ate a diet that consisted of a LOT of food, and ended up putting on 12lbs in 6 weeks. I drank 2% milk, as we did not have whole milk in our dinning hall.
Prior to drinking a gallon of milk a day, I had legit not had milk as a beverage since my childhood. This required a re-acclimation to milk, which I will discuss momentarily.
WHAT GOMAD IS NOT
Healthy. Understand that from the forefront. That's not the point of it. If your goal is maximal health, you should NOT be drinking a gallon of milk a day.
Sustainable. This is a blitz approach, paired with extreme training, to get extreme results. You won't be doing this for life. 6 weeks was right for me. Some folks run it for longer.
A first resort. A lot of trainees want to jump onto GOMAD right away, but this is something that's done AFTER you have real nutrition sorted out. If you're living off weight gain shakes and don't know how to boil water, do NOT do GOMAD. Learn to cook. Try here
WHAT GOMAD IS
New 40 gallon water heater gets cold way too fast even with the temp set to 140. Doesn't even last 30 min. Previous rental house had a 20 gallon tank that was turned to 140 and it easily lasted for over an hour long shower (wife rinsing out hair color from long thick hair).
It's a single element tank. Could that be the issue? There is no sediment, it was checked out and everything was fine. Any thoughts or ideas? Considering just replacing it.
Edit: people keep mentioning the shower head. It's the Exact same shower head we used in the rental home with the 20 gallon tank. We bought our own and took it with us
