Grab a rope and start skipping.

Skipping recruits most muscles in your body, causing it to be more taxing hence burn more fat.
Skipping is less damaging to your joints than other exercises, such as running
Skipping improves lower body coordination and cardiovascular health
Skipping has a low barrier to entry - everyone has easy access to a skipping rope and is able to skip at least for a bit

However, if you want to burn fat, the most effective way would be to reduce the amount of calories you take in, rather than trying to burn excess calories through exercise.

Eat less, move more. We would need a lot more information on your diet, height, current weight, etc.

If all you want to do is lose weight, you're going to need to cut your calories and burn more than you take in. Clean up your diet and you won't even need to exercise until you hit a plateau.
