I can honestly say there isn't a single thing I miss about being fat. As I lost 75 pounds, there were a bunch of improvements I noticed along the way. Problems that I was living with that I didn't really notice, but became clear as they went away.
This list shouldn't be a comfortable one to read. It needs to hurt to inspire me to stay fit, to inspire you to either lose weight, to stay fit yourself. Hopefully you can relate or think of your own frustrations.
Here's a quick list:
Problems like I listed above happen gradually over time and you really don't notice them, that you aren't living up to the potential of the sacred body and life God gave you. Yeah, there is some sacrifice involved in controlling what you eat and learning the discipline of exercise. But how small of a sacrifice are those compared to all of the many, many problems brought on by being overweight? A small sacrifice indeed.
If you are overweight and have some of these problems or others, I encourage you to think about your quality of life. I promise you that being healthy is worth it.
