If you want to lose weight, first thing to do is to make a life time choice. What helped me was replacing unhealthy foods with healthy options. For instance, instead of buying french fries, bake them in the oven lightly sprinkled with olive oil. The key is to cook your meals from scratch, therfore, you can monitor your portions and subtitute if need be. Don't let advertisment tempt you.
