You want a serious answer?
This is how i lost weight:
Keep it under 130 heart rate and do it for a long time. Doesent matter if its running, cycling or some other machine. Do it for half an hour 1st if you can, then increase it by 5 minutes each training. Alternate between rutines to keep it interesting. My training, at the end of the weight loss period, was 30 minutes running, 40 mins cycling and 20 mins on a stepper, all around 125 heartrate.
How do you know if its fat burn and not cardio? If you can normaly speak while doing it (you are not huffing and puffing) its fat burn.
Buy some l-carnitine, its dirt cheap and it helps. Take 2 pills 30 minutes before each training.
Cut bread and sweets completely out. No exceptions.
When you have lunch, put how much you would normaly eat on a plate. Now eat half of that, eat the other haf in 2 hours. Eat a healthy and large breakfeast, i ate oats and milk with honey. Eat some veggies or fruit for dinner. When you feel hungry drink water, drink shitloads of water all day.
The harders part is maintaining your discipline. You have to reaaaaaly want to lose weight and have strong willpower.
Its not rocket science, its just spending more energy than you put in your mouth.
Good luck
