Activity anorexia signs and effects

In our books, it talks about the concept of "activity anorexia". This is something that is becoming more prevalent every day in people. I talked to some professionals at the gym I go to, and they told me that this is something that is becoming more and more popular. I went online to do more research and found out that there are several signs for someone with an exercise disorder. These signs include:
1. Becoming preoccupied with exercise and weight loss
2. Closely tracking how many calories they burn when working out.
3. Becoming anxious and angry or feeling guilty when missing a scheduled workout.
4. Measuring yourself to see how think you are after a workout.
5. Seeing your body differently than others.
6. Becoming angry or defensive if someone suggests that your exercising habits are extreme.

One thing that I learned is that size is not a clear indicator of a person with an exercise disorder. A person can be normal or overweight and still have an exercise disorder. If you are trying to pinpoint if someone has an exercise disorder, their attitudes are a better indicator than their size. Some of the effects of eating disorders include: heart problems, weakened bones and joints, respiratory issues, and a weak immune system. Almost no gyms across the country offer help for people with exercise disorders also! People are extremely nervous to approach the situation.
