Strategies To Lose Weight Fast

Walking at a certain speed wherein I feel muscle “strain” (I can feel the burn!) is very healthy for me, I know. But I want to know how fast I can lose weight by doing this daily and eating a healthy diet full of a balanced amount of pasta, vegetables, meat, and water.
Can I lose five-ten pounds in 5 months or so? Or how long, and how many pounds?

Does water help you lose weight?
