Clean teeth linked to slender bodies: The frequency of your teeth brushing can be connected to your weight... Those who tend to brush after each meal are normally slimmer. Studies showed that overweight men often went a day or two without brushing at all (ewwww....)
"In a survey of the everyday habits of nearly 14,000 people whose average age was in their mid-40s, Takashi Wada of Jikei University found that those who managed to stay slim tended to brush their teeth after every meal." (source)
So brush after each meal...floss at least once a day and for god's sake...use a little Listerine! Your waistline will thank you for it!
