About the weight gain on raw milk.
I've been drinking 2-3 gallons of raw goats milk for over a year now and lost 20 lbs. At the same time though, I switched to a primal/paleo/caveman/... diet cutting out all grains, all nuts and all beans and processed sugars.
I'm at a normal weight, stomach is flat but doesn't show a 6-pack.
Insulin is what drives weight gain, keep the raw milk and a few berries a day your only Carb intake a day.
It is literally impossible for me to get fat on this primal diet. Nuts put the weight on, not raw animal milk when fed grass. If you're aware of your daily carb intake there is NO way you will gain weight drinking nutritious, raw milk.
Just make sure you don't show any symptoms like bloating, cramping or headaches after consuming it. Sometimes when consuming too much (raw) milk you end up with constipation because of the imbalance of Mag/Cal. I don't recommend drinking tons of milk over long periods of time. Take seasonal breaks if you can, like during winter months when goats tend to 'dry up' anyways. 1 cup of raw milk a day for the rest of your life won't hurt you, but gulping down a quart or more a day will probably cause allergic symptoms over time and your body will let you know it. I know so because that's where I currently am.
My massive milk consumption is finally dwindling down, hopefully I can completely stop drinking milk all together this late fall + winter.
Raw milk is a great way to get all minerals and vitamins and hundreds of other good things not even discovered yet into your body and really nourish your skin, nails and hair.
Some people say even raw milk is bad for teeth. I've had the opposite experience. My teeth got stronger, the bone density in my face and head seems thicker and soft spots on teeth filled in with hard enamel.
Don't let people scare you from drinking raw milk. See for yourself what symptoms you might get (gas) and just drink either less or skip it. The gas is due to the fermentation process it undergoes when milk hits acid. Kinda like when you put vinegar and milk together, lots of air bubbles. It'll be gone the next day.
