However, calorie intake from carbs have increased in the population proportionately to the rise in obesity rates. In other words, overweight people do not typically EAT more than the average weight person - can we shake this lazy and undisciplined stereotype?

This article isn't saying what you think it's saying.
What it's saying is this:
- energy intake has gone up about equally amongst all weight groups
What it doesn't say is this:
- weight groups all consume the same amount of energy
In other words people of all weight classes eat more than they used to, but the article doesn't touch on the reference point of each weight group.
As to the assertion that 'calorie in-take amongst weight groups is pretty much the same' as a standalone argument, I just don't buy it. Doing a quick survey of the people I work with alone provides a pretty strong correlation between weight/diet. The opposite being true just doesn't make sense, as it's literally calorie count that has the biggest affect on weight-gain.
