Sure, but the view that it's just sugar that's bad, is even more overly simplistic, and in fact harmful. Obesity is always more deeply rooted in habits, comfort, stress and the way a person deals with things, than it is with just sugar---it's a behavioral issue that needs to be tackled at a deeper level. One calorie is one calorie, regardless of were it comes from.

You'd find very little actual scientific backing for your statement, from papers that haven't been debunked[0]. That sugar itself is bad is an age old meme that needs to die. Similarly, that kids get hyperactive with sugar is also a myth[1].

Now, your other argument that you might "feel" hungrier, is something else. You have still gotten the energy you needed, it just doesn't feel as filling, perhaps.

Your reference [0] is talking about the concept that such a thing as "sugar addiction" exists. That is not at all what I was arguing. The fructose metabolic pathway is well known, and particularly in the US, excess fructose in the diet is common due to the corn industry.
