I've lost a lot of weight, but I feel like my body looks exactly the same... ㅠㅠ

How is it for everyone when they go on a diet?

I've been working hard on my diet and exercise, so the number on the scale has dropped quite a bit, but when I actually look in the mirror, it doesn't seem like much has changed from before, and I feel so disheartened.

It feels like only my bones have worn away, while the excess fat and body fat I really wanted to lose remain exactly the same... My body fat percentage hasn't decreased, and I wonder if I've only lost muscle, but my body lines don't look pretty, so it's upsetting.

I guess managing body fat percentage and muscle mass is more important than the numbers after all. How does everyone else overcome this kind of situation...?
