C.O.
You may not be interested in hearing this, and you have every right to not listen. But I truly believe that food is 90% of losing weight and excercise is 10%. I am not saying that excercise isn't important, it is crucial for a whole host of health related things. But if you don't rework what you are eating, you may not see the results you want. I blog about whole and minimally processed foods at www.thetableofpromise.blogspot.com My recipes are not always 'diet' recipes. But I try to stick with whole food ingredients and minimal additives, etc. The combination of whole foods, lots of veggies and giving up the processed stuff was the only thing that helped me lose weight.
Best of luck!
