Before everyone jumps on the low-carb bandwagon there are a few caveats to note:
1) All the participants had metabolic syndrome so the results might not be generally applicable.
2) The meals were fixed portions, so we don't know how it affected appetite or how it compared to previous eating habits.
3) We don't know what would happen long term. For instance all the participants followed the same pattern of steadily increasing carbs and decreasing fat, so it could be the body reacting to the delta.
I just mention because most people are really interested in the question "if I want to lose weight and/or reduce my risk of heart disease should I eat more/less fat and more/less carbs". But that question is incredibly specific to one person and very poorly defined beyond that. This study says in these very specific circumstances the answer is more fat and less carbs, but that's not necessarily true in general. To think it does give the general answer only sets one up for a future accusation that science is always wrong when a future study with slightly different parameters seems to reach a different conclusion.
