One aspect you'll need to consider is that you're going to be intaking large amounts of saturated fat. Saturated fats have their importance in your daily diet, but you don't want the majority of your fat intake to be composed of them. There is an inherent flaw in using whole milk to that degree, and it's the fat type dilemma.
He's looking at 1500-2000 calories from whole milk. To keep this simple, let's use 1750 and split it up the middle. He then plans to add another 1000 calories to the mix from meats, veggies, fruit, and eggs.
I don't know his target macro breakdown, but let's assume he's going with a pretty typical 30% of his calories from fats.
Fat calories = 825 Fat grams = 91.5
Now, he's getting 1750 calories from whole milk, which equals 11.6 servings (one serving = 150 calories).
4.5g Saturated Fat x 11.6 = 52g of Saturated Fat from whole milk
Now, remember that to keep his fat intake reasonable, he should be around that 90g total mark. The whole milk nets him 93g of fat in total, with over 50% of those grams coming from saturated fat.
He might as well forget about whole eggs at this point, as his fat intake has already been satisfied through his milk intake. So, we can safely say that over 50% of his total fat intake is technically a majority, and is also more than is recommended for healthy daily fat intake.
Of course, I'm assuming some things, but the things I'm assuming are completely reasonable. The original poster can correct me if any of my assumptions are out of line.
Based on price and lactose content, I'd recommend a good whole milk protein powder over whole milk. You can probably find good quality affordable bulk powders. You can buy half and half to mix in with it for tasty lactose free and cheap calories. That'll cut down 90% or so on lactose, which IMO would be an issue for 90+% of people at that many calories based on the sheer volume of grams of lactose content. BUT... Go ahead and try your approach first and let us know how it goes. If it works, then great. Calorie for calorie, eggs are pretty darn cheap too.
Did it. Got me from 74kg to the place I am in my avatar. I didn't develop any kind of intolerance the 2 years I had been doing GOMAD. Now, I am drinking about 3/4 of a gallon a day, without any problems. Milk is great.
drinking heavy cream is starting to become increasingly more popular with powerlifters/strongmen. or i guess just anybody looking to get a good amount of calories in easily. i'm pretty sure they just mix it in with their whole milk.
Just stopping by to say hell yeah to heavy cream. It doesn't cost all that much more than milk and you can pour it all over everything. Or just drink it straight. It's your friend. (if you're not intolerant, which I would assume you're not)
2020wellness, care to qualify your statement about my good buddy, saturated fat? Let's get some discussion going up in dis.
