I found some information about your "milk squats" program. Hahahaha.
Which Milk to Use for GOMAD. Don't waste your time with low fat, skimmed or half-skimmed milk. They're lower in saturated fats & calories and won't give the same results. Go with whole milk, it also tastes better.
Whole Milk. Full fat milk which contains 3-4% fat. Alternative names: full cream milk or homo milk.
3-4% fat. Check the nutrient data on the whole milk you buy. It should contain 3-4g fat, 3g protein & 5g carbs per 100ml.
2400 Calories. Whole milk contains 60kcals per 100ml. This accounts for 2400kcals when you drink 1 gallon whole milk.
