Emphasize body trust. Bodies say when they're hungry. People come in all different weights and heights. You and your body are unique in all the world. Accept that weight may not change even when there is progress in self-care.
Higher weight is correlated with health problems, especially in later life.
Because we have no treatments, preventing weight problems is preferable, which means all kids need to hear the message. Care about how they are doing, not what they weigh, and develop a relationship that communicates this to them. It would seem that if kids are getting heavier and this could be a problem medically, we should help them lose weight. We have evidence that problems with eating can be treated. Support exploring playful physical activity, preferably for the whole family.
