Was talking about this at the weekend.
I weighed both my girls, 7&10.
Both came up as "underweight". At 20kgs and 35kgs respectively.
A/. They both look perfectly sized.
B/. I don't know how a 35kg 10yr old can be considered underweight.
However, our discussion centered on the fact that the youngest, doesn't stop eating. And it's not all healthy stuff, a lot, admittedly, is crap.
So we couldn't figure out how they stayed slim.
Then we realised, neither of them drink fizzy drinks.
And nor do they eat processed food. I cook everything from scratch. Not because I'm super woman, but because I was taught to.
Compared to the fat kids in their TKD club, who at breaks are drinking isotonic drinks, and talking about what snack they'll have after...despite eating before they came.
We're the other way on, a snack before and their dinner after.
Education is what we need. Taught how to cook. Understanding to listen to our bodies.
The 10yr old doesn't graze, and self regulates her sweets (Xmas sweets for example, still over half left). But she does eat big meals. She's also more sedentary and chilled.
The 7yr old, grazes all day, but never stops moving. Even when she's reading a book, her feet are jiggling.
