ALL BODIES ARE BEAUTIFUL. The human form and physical ability is miraculous. I do not believe that one shape is better than another and I don't believe in a "good" or "bad" body.
SHAPE AND WEIGHT DO NOT DEFINE VALUE. I love to workout. I enjoy getting smaller or bigger depending on what I am working on. However, I don't think my value (or yours!) changes based on shape. I don't think thin women are bitches and I don't think that larger people are unworthy.
I BELIEVE IN FEELING GOOD. Weight is bullshit and has to do with your relationship with gravity. Who cares - my weight fluctuates and so will yours. However, I believe in feeling good and being able to live your life - i.e. lifting heavy things, running and jumping. I recently went back to an eating style that does well for me and I lost weight. I am happy because I feel good. If I felt crappy, I would stop.
I BELIEVE IN MOVEMENT. There are enormous neurological, physiological and emotional benefits to moving. I believe in fitness. I think you should find a way that feels good for you to move. I also think you should eat in way that makes you feel good and supports your lifestyle.
I BELIEVE IN PERSONAL CHOICE. If you want to lose weight, gain weight, tattoo yourself, augment yourself, change because it makes you feel good. DO IT.
