Think back to when you were about 7 or 8, were you...
Think back to those days when you were in school and compare the shape and size of your body to the other children of the same age.
Many people who are much bigger now than they were before, perceive their childhood shape as very lean and thin.
Similarly, many people who are currently lean perceive their childhood weight as well above normal.
But don’t compare your childhood weight to now. Compare your childhood shape to other children of the same age.
