Why is it important to lose unhealthy weight in a healthy way?

so you don't gain the weight back after the weight loss and so you aren't unhealthily overweight.

Explanation:

the more fit you are, the faster the recovery. your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. this “recovery heart rate” is measured as part of an exercise stress test.

because health skills are tools and strategies and also practical skills are also something you need to learn (like tools and strategies) and put it in reality.
