With minimal exercise, walking and calisthenics?

Oh yes! It's very healthy and definitely promotes weight lose but if you don't change your habits such as drinking soda and eating junk food, you won't see the best results.

I did the same thing whole grain fiber cereal with soy milk and pure whey protein and with that had a cup of green tea with lime and 5 splendas and i wasnt hungry up untill 6 pm when i ate dinner and i didnt eat anything but drink blk tea and munch on some fruit later on and i lost about 8.33 pounds a month bout 2.09 pounds a week

Yup. Excellent. Kept me feeling full longer. I like to add a piece of fruit or two also. I also like greek yogurt..high in protein. Can't skimp on the protein if you are going to eat low calorie or you lose all your protein.
