To enhance your weight-loss goal, there are two main components:
1) Diet - this is the biggest thing that everyone forgets when trying to lose weight. It is possible to lose huge pounds without ever doing exercise. The key is caloric deficit. Find out your basal metabolic rate (BMR), and that is how many calories your body expends in a single day. For reference, a pound of fat is equivalent to 3500 kilocalories (for science people, 1 kilocalorie = 1 Calorie). For example, during your diet, you have a caloric deficit of 500 Calories, you will lose 1lb of fat every week. This is what you should strive for. Another key element for a diet is to remember it is a lifestyle change. That is why "fad" diets are mostly unsuccessful. Find healthy foods that are also tasty (my opinion the best is grilled chicken breasts [no fat, no cholesterol, high protein]).
2) Exercise - Walking, running, and biking are the best aerobic exercises. A good investment would be a heart rate monitor. Use the heart rate monitor and then exercise at a pace for aerobic exercise (usually around 140-150 beats/min), and that will net you the best results for cardiovascular gain. It will also keep you at a pace that wont let you stop after 10min from exhaustion or from being able to go for 3 hours straight.

Hope this helps, good luck with your plan, and PM me if you have any questions.
