Will this work to lose weight & how many months/weeks (estimations) do you think I will see results?

yes, this will work to loose weight. In fact, it's very smart and sensible. Good for you. You won't see results right away unless you're eating like trash and not exercising at all now. I'd guess you'll start seeing serious results within 2 or 3 months, and noticeable results within a month. At least, that's what happend to me. A lot depends on how much you weight now. For example, If you're female and 150+, you'll see results quicker than someone who weighs 130.
