Sir or madam i am suffering from the disease high obesity so what is the benefit of skimmed milk instead of simple milk can i take it or not please help?

Skim milk: Drinking skim or low fat milk is fine. In general, a low fat diet is fine. Focus on eating protein, vegetables, water, and avoid excessive intake of carbohydrates, sweets, sodas, etc. Exercising regularly (cardiovascular exercise, not weight lifting) will help tremendously as well. Low impact sports like swimming or the elliptical machine will save your joints. It takes time but you can do it!
