I've been walking/ 4 +miles a day to get to 10,000 steps as far as weight loss if i eat will & walk will i lose weight quickly..?

Loosing weight too: fast can be dangerous. See your doc first, and then consider lower carb and higher protein intake. Exercise daily if possible, even brisk walking 20-30 minutes is helpful. Above all, like yourself and others no matter what the scale says. Peace and good health. "Disease Proof" by David Katz provides a healthy blueprint for life.
