Since I started smoking 4 years ago, my circumference has decreased by about 4 centimeters, not to my thighs. They say that I don't gain weight on my legs. There's no yo-yo, I only gain weight on my arms... but even if I gain weight, it goes back to my legs and when I lose it, only my arms lose, so I'm the same as before. I heard on ㄱㄴㅇㅇ that there is no yo-yo and your legs won't get fat even when you're pregnant. Is this true?
