Going on a diet!!!!!!?

Asked: Going on a diet!!!!!!?

Hi I am a female, 20, 5'4 weigh about 145. I would like to weigh 130. I have cut off junk food, and soda. Only drinking water and some juice, mostly cold water. I am now eating salads. And other healthier foods. Can I lose at least 10pounds by eating healthier without too much exercising, how long would it take? I will be getting a treadmill in two months so in the mean time, how long wouldit take if I eat healthier, and take occasional walks. And have you done this? How much did you lose and how long did it take.
