The problem with orange juice is the sugar. Specifically the fructose, as sugar is a bond between fructose-glucose. The problem is that fructose can only be metabolized by the liver, and the metabolism of fructose has negative side effects. The liver can handle some fructose over time without any problems, and the threshold of being overloaded seems to differ between people. But in general liquid sugar can overload the liver for many people. Over time the chronic effect is that the liver becomes resistant to insulin. Because the liver has to handle lots of glucose with insulin, the resistance to include causes a body wide increase in insulin. Studies have shown this causes a chain of events that causes leptin resistance. When you're leptin resistant, your body thinks it's starving. It will conserve energy and drive up hunger, making fat loss more difficult but still possible.
In short, sugar can break satiety mechanisms in the body and orange juice is no exception.
When you eat whole fruit, there is fiber to slow down the digestion of fructose. And the load of fructose is lower. Kind of like drinking 2 beers on an empty stomach versus 1 beer after eating a large meal. (The analogy goes even further than that because alcohol is fermented fructose and it have very similar metabolic paths in the liver.)
