As a coach I am not going to discourage exercise but remember it takes a depressingly huge amount of activity to burn the same number of calories that you can consume effortlessly.
Careful control of what you eat is by far the more important part of the equation as far as weight loss goes.
The science is very simple - "eat less - move more". Its all about calories in and calories out. Genetic factors account for only a very modest percentage of excess weight.
Exercise is great for reasons of health and fitness but if your only goal is burning fat you can increase your daily calorie burn significantly by simple changes in habits. Stand more and sit less. Take the stairs insted of the lift (elevator) walk as much as possible.
Muscles are fat burning machines, so you can increase your basal metabolic rate by weight training to add muscle bulk but remember it will disappear again much faster than you will put it on if you can't maintain your regime.
Losing a pound a week is a realistic goal. Diets that claim rapid weight loss are a con at best and possibly dangerous. Rapid weight loss is down to dehydration and loss of glycogen which will leave you feeling tired and unable to exercise effectively. It has nothing to do with burning fat.
Eat breakfast but avoid sugary cereals. Hi GI foods cause a spike in blood glucose, your body then releases insulin which drops your blood sugar lower than it was previously - rinse and repeat. Try low GI foods like porridge, and complex carbs. Never fast, it will trigger a drop in metabolic rate as your body prepares for famine. Eat smaller portions often. Don't diet, aim instead for a sustainable change in lifestyle.
Take a pound of butter from the fridge and imagine having that amount removed from your body every week. Not a bad goal is it?
