Thank you! Exercise should be completely supplemental to overall health, not to lose weight. The amount of times I've seen people eat an awful meal while trying to lose weight because they "worked out extra hard" is astonishing.
Losing weight is almost completely related to what you put in your body. While you can certainly lose weight from exercise, it's by far not the most profound way to do so.
Congrats on your weight loss by the way, former fat kid myself, I know it's not an easy process and keeping it off is just as hard!
