Being Woman

Why do men lose weight so more easily than women? Or is it just my hubby that is so? He went down from 65kilos to 57kilos in three month without needing any diet pills whatsoever while I did not lose any weight at all. I don't understand it at all coz we eat the same meals at the same time and we even sleep the same amount of time. The only difference is that he smokes while I don't. Hmm... is that the cause??

Cheerio...
