Did you see a table with targeted heart rate on your cardio machine (treadmill, elliptical etc.)? The table has two zones - fat burning zone with lower heart rate and cardio zone with higher heart rate.  Some people keep their HR (heart rate) low and are afraid to go to cardio zone because they want to burn more fat. I think that this is one of the myths of training. When in cardio zone you’ll burn more calories and you’ll make your cardio-vascular system stronger. Number of burned calories is what counts in weight loss. You need to burn more calories that you take in.

Here is the example: You’ll work out for 40 minutes in fat-burning zone, you’ll burn 100 calories - 60% goes from fat that means that you’ll burn 60 calories from fat.
You’ll work out 40 minutes in cardio zone, you’ll burn 300 calories but only 30% goes from fat. When you do the actual math, you can see that you’ll burn 90 calories from fat.
It really makes sense to work in cardio zone and burn more calories. Do interval training if you are not able to stay in cardio zone for the whole training. You’ll burn more with intervals that if you’ll keep your intensity stable.
Remember, number of burned calories is what counts!
