i'm finding that just plain old milk is amazingly well balanced, i have just a nice amount of fat and the protein plus some good resistance exercise is increasing muscle mass. I dunno exactly how much muscle mass i've gained but by eye and the scale i'd guess i'm up 3kg muscle weight over my lifetime average.
the milk gives you a fair whack of carbs and that extra muscle is a little hidden under a reasonable fat layer, maybe a little more than i'm used to but according to BMI, puts me in the 'healthy' range where before i was just under.
it's carbs as calories that give you fat. the body simply does not absorb fats that it can't immediately use to make glycogen.
imo, the only carb that is not a disaster is lactose, because it doesn't make your mouth into an acid factory. it's been one of my favourite things about the milk diet, no more funky mouth, it's even resolved some serious nerve pain problems i had developed, i think i now have grown a little coating of enamel over a lot of broken exposed areas, i get no pain from cold or spices now. it was getting really bad because just malts were making my teeth get pain and my half dead wisdom tooth would get swelling under it and shift upwards with the pain.
literally doesn't happen anymore.
the other great thing about milk is it makes your skin all shiny and soft.
