If it doesn't work for a month, there must be something wrong with the method. You think running for a month should work. It takes more than 30 minutes for fat to burn normally. Fitness needs to exercise some strength things, so as to burn fat faster. Your ineffectiveness should be running time, insufficient speed, too long strength interval, failure to achieve burning effect and too long rest time. It is recommended to run at a speed of 8 for 40 minutes, and do all the strength types, about three or four groups. If you have a bike, run it. It won't work again. Please teach privately.
