Keep your reason for being on SP in focus. Are you here to become healthier or skinnier? Contrary to popular belief not everything skinny is healthy.
When your goal is to become healthier you become invested in providing health for both your body and mind. You take pride in the things you are training your body to do and your mind to understand, both will become stronger.
Honor your body and the good things you are providing. Become your body's best friend. The scale won't rule your life.
If it is more important to be skinnier right now, maybe trying a simple diet would be easier than embarking on a lifestyle change. It's a whole heart committment.
