Yeahh, I got tired hearing my female friends complaining about their weights and they are just looking fine. Numbers on the scale don't represent anything. I told them what matter is whether you girls are healthy. Seriously, I have a friend who is fairly skinny but her cholesterol level is very high. Your appearance is not based on the numbers on the scale.
What really matter is you girls being healthy and happy. Stop worrying the numbers on the scale. Go to the gym, eat right, be happy, and have enough rest.
