Just from moving to places where I generally walk everywhere (college, major city) to places where I can only really drive (various smaller towns and suburbs) I have fluctuated in weight up to 15 pounds without any change in diet. In both places, I would lift weights 4-6x a week.

I have had family members lose 60+ pounds from introducing daily walks into their lifestyle.

I am still a proponent of more vigorous exercise and particularly resistance training, but you cannot discount the benefits that going from not walking to walking can have.
