What is body image?
Your body image is how you think and feel about your body. Body image involves your thoughts, perceptions, imagination and emotions. People can experience a positive or negative body image and can be influenced by both the internal and external factors in our lives. Your body image does not necessarily reflect what you see in the mirror or what other people see. For example, a person may think and feel that their body is much larger or smaller than it is.
Body image issues affect people of all ages, genders and across all cultures.

The diet cycle
The typical diet cycle involves:
- Starting a diet – often quite rigid and limits the amount, type of frequency of food and eating.

- Weight loss is regained – this can be associated with eating foods not part of the diet, eating when not hungry, and sometimes overeating or binge eating.
This weight cycling (repeated cycles of weight loss and weight gain) may put you at risk of physical health complications such as .
If you are concerned about your own or your child's weight, consult with your GP (doctor) or dietitian, or a paediatrician.
