In : In my opinion weight loss is 80%diet, 20%exercise. It sounds like you are pretty active, therefore the diet must be the reason you are not losing. You may think you are eating "pretty healthy" but i guarantee you there is probably a lot of room for improvement. Ask your doctor to refer you to a certified dietician. The dietician will go over what and how you eat, and help you make the appropriate changes. Once you begin doing this you should see the weight come off. Surgery should be your last option, ; really focus on the diet and maintaining a consistent relationship with a dietician. Good luck! don't give up.

Cardio Mix: If you have adipose tissue that you'd like to lose then consider an increase in cardio and a balanced diet. However, do not always do the same exercise or you will increase your risks for stress injuries. Mix things up with running, biking, swimming, or circuit training. Ultimately you need to burn more than you consume. Best of luck!

Calorie reduction : Is the only way to lose weight. Eat less that you burn. 3500 calories for 1 pound of fat. Exercise like fast running for 1 full hour can only burn 500 to 600 calories. Exercise will tone the body , but not be a very big part of actual weight loss. Without major attention to calories.
