If you feel like giving up..
Don't do it! I was embarrassed to work out and say no to "normal" food like fast food. But now in my body 20 lbs lighter without all the back pain I had the choices just come naturally! Don't give up keep trying new things and remember each time you eat something healthy or do a work out you are one step closer to your goal! I had a whole weekend of buffet food but it doesn't mean I can't get back on track. No matter how bad you mess up you always have your body to burn it off. You don't need a gym or fancy health foods. Most of my veggies come from the frozen section. Just make what changes you can. You deserve to be healthy!!
