Yes. You can drink 2 cups of milk daily as part of a diet plan and as long as you do not go over your calorie intake limit.
HIdden Sugar. If you are obese then the enemy is sugar. There is a lot of sugar in milk. Many humans are mistakenly worried about low fat and non fat milk when in reality the problem is the sugar. Too much sugar in the diet leads to obesity.
Yes. One 8 oz cup is enough but it is perfectly fine to drink two cups a day, but i would recommend drinking a lot of water and if your looking for protein trying eating some sort of bean.
