You are right, my mistake! I was mixing it up with another study. Unfortunately, it is too late to edit my comment.

However, coincidentally, the same conclusions still hold, since it turns out the pigs ate very similar amounts of food on all the diets, except the 5:1 n6:n3 diet, where they ate a bit less. (And that was the diet where the pigs gained the most weight.)

Sorry about the error!
