I've been on the cottage cheese diet and take a multivitamin and lost 20 pounds!? Any drawbacks? - cottage cheese diet

I have a lot of low fat cottage cheese as I want! 320 calories for a tub full of protein and 60 grams of a bathtub. No fat! Multivitamins and filled with ricotta, which I need in my diet! And I'm losing weight! My question is, is it healthy?
