"Sentences with the phrases "any parent who" and "any child will" carry no weight with, well, any actual parent with experience raising any actual child."

I am an actual parent of four (and grandparent of one, so far).

They are all just about at their ideal height/weight ratio, and very healthy. Best of all, though my children been making their own choices for years now, they know what the healthy choices are (and have even turned around and taught me a few).

Sorry if I sound self-righteous. Actually, I'm just grateful that I found something that works. You, of course, may feel free to experiment with your kids.
