Unexpected weight loss

So I did my life insurance policy last week and today the company sent a woman over taking my weigh,t urine and blood turns out I lost some weight. I’ve been weighing myself but my scale shows no change, the woman’s scale had me at 205 mine had me at 210 I look up to my fiancée with the dummy look on with my head to the side like huh?! I say fuck charge it to the game I ain’t complaining I’m 205! That’s 113 pounds down since march 2011.
