The only way to lose weight is to eat less. Exercise and all the rest are indeed helpful, but weight is about how many calories you eat. Which of course doesn't mean you shouldn't exercise at all. Sport contributes to your overall vitality and good looks. But you don't need to go to extremes to lose more weight because actually you will not. I've seen people who overexercise and undereat and the result was the scale wouldn't budge a tad. Instead you should aim for a balanced diet combined with some exercise, as much as it is convenient and pleasant for you. It could be as much as a walk in the park in the evening. As long as you are at a calorie deficit, you will still be seeing great results.
