According to the link, those who slept less had an increase in appetite, which is the opposite of what you claim in your first sentence. From the article: > "After the night of abbreviated sleep, the men consumed more than 500 extra calories (roughly 22 percent more) than they did after eight hours of sleep. ...

I think what you want to say is that the studies have shown a correlation, but it might not be a causal relation.
