There is no really fast
, way to lose weight
healthily. I agree with using the food
tracker to see how many calories you are eating each day, then start making small changes, like drinking water instead of soda (including diet soda), or snacking on raw veggies, rather than a candy bar, yogurt in place of ice cream, etc.
Exercise is essential to losing weight AND being healthy. There are exercises you can do that should not bother your asthma.
