I love it. Every flavor. It really does taste like a real milkshake when you mix it with milk, no shit. However, I am never on a diet and don't care how much fat, carbs, or calories are in it. I will say that when I do incorporate it, I have never gained fat from it, and I actually look leaner (for me, lol). But damn, it is the best tasting supplement I have ever had, I even made my girlfriend, my sister, and my mom try it and they all thought it tasted like a milkshake.
Sorry if I didn't help with the fat content concern, just my 2 cents. I personally think I look slightly better when taking this product.
