Your relationship with your body and how you view it can affect everything you do in life. When you’re feeling well and looking good, you give little thought to where you go or whom you might run into. But if you’re feeling self-conscious or preoccupied with something you don’t like about your body, then you might avoid other people or situations where others might see your perceived flaws. For example, one woman admitted that when her acne flared up, she spent days isolating at home. This next exercise will teach you how to accept your body nonjudgmentally.

• Begin by observing the negative thoughts and criticisms that you have toward your body, such as “I’m fat and ugly” or “I’m too scrawny and need more muscles” or “I hate my thighs.”
  
  
• Take a quiet moment to experience these random negative thoughts. Then, begin to practice nonjudgmental acceptance of yourself by saying aloud or thinking, “I’m not perfect. This is the body that I was born with and I am learning to accept myself without judgment.”
  
  
• At this time, you are simply observing any discomforting thoughts and not reacting. Notice your thoughts but resist any inclinations to agree or disagree. You are merely accepting that you have thoughts, that these thoughts come and go, and that they are always changing.
  
  
• One mindful way of paying attention to your negative thoughts is to respond to them by acknowledging what you observe about your body, and then to practice acceptance without attaching a judgment or opinion of yourself or your body.
