You can see that this girl has gained a lot of weight, but her figure has improved. She has gained about 13 pounds, but her waist has become thinner. This shows that if you only look at the number on the scale when exercising to lose weight, your self-confidence will often be hit. The data we should look at is: body fat percentage. It is the proportion of fat in your body. Otherwise, I think that simply losing weight is meaningless - so it doesn't make much sense to look at the scale. All my foundations and methods are based on body fat percentage and visual effects.
