My understanding is that the fat burning zone is in zones 1-2... not up in Zone 4 or more.

My understanding is that in order to lose, or to prevent yourself from gaining weight, you should do 3-4 workouts (minimum 30-40 minutes) per week at an aerobic level which is an elevated heart rate, but you are still able to talk/have a conversation.

If you workout too much in the anearobic zones, your body may actually begin to work against you...

Thats just my understanding...
