If I eat like this, will I lose weight.?

Sounds like you are doing good. The walking is great. You should be seeing results on the scale soon. Did you leave anything out of your menu? Like, do you put mayo on your sandwich? Are you putting anything fattening on your veggies? Little things like that add up. I wish you the best of luck, and hope you can stick to this. I know it is hard. I have struggled all my life. It is all about attitude. You have to really want it. You have to want to get healthy more that you want that piece of cake or pizza. You have to look at the foods you used to crave, for me my weakness is bread and potatoes,,,you have to look at those foods and think to yourself,,,is eating that going to help me get to my goal of being fit and healthy? If the answer is NO, then you dont want to eat it. Be strong!
