I signed the Health at Every Size Pledge.

From the HAES website:

“Health at Every Size” is based on the simple premise that the best way to improve health is to honor your body. It supports people in adopting healthy habits for the sake of health and well-being (rather than weight control). Health at Every Size encourages:

• Accepting and respecting the natural diversity of body sizes and shapes.
• Eating in a flexible manner that values pleasure and honors internal cues of hunger, satiety, and appetite.
• Finding the joy in moving one’s body and becoming more physically vital.
