Saying "I do" could have an impact on your waistline, according to a survey conducted in the UK by Forza Supplements and reported by the Daily Mail.

Of the 1,000 people polled for the study, a majority admitted to growing heavier since tying the knot. For 40% of respondents, weight gain occurred at a rate of 4lbs per year on average.

While 22% of those surveyed reported gaining 2lbs annually since entering marriage, nearly as many respondents said they gained a whopping 6lbs per year.

Somewhat reassuringly, almost a fifth of those surveyed (18%) indicated that they had not seen a change on the scales.

When asked to explain the reasons behind their sudden weight gain, over 50% of respondents who had become heavier since their wedding day confessed that they spent more time snacking together in front of the TV. A majority of respondents also indicated feeling less pressure to maintain a slim figure once they had settled into the commitment of marriage.
