When the honeymoon is over, it's not unusual for newlyweds to notice their waistlines expanding.
A 2011 Ohio State study found that weight gain of about 20 pounds is average among people who get married (especially for women), and according to Texas healthcare professional Judy Gaman, there are lot of good explanations for the increase. In the video above, she explains that after the wedding, lifestyle patterns change, leading to more food consumed and less activity.
One major culprit is television. Gaman said married people tend to watch more T.V., since they're not just watching the shows that they personally want to watch.
"You watch your show, but then you have to sit through your spouse's favorite show, and then you usually have one you watch together," Gaman said.
Moving in with a spouse who is a good cook can also lead to more lavish meals, and the cook will often ask his or her spouse, "Do you want some more?"
"Saying no might be taken as, 'I didn't like the meal,' so they'll continue to eat even after they're full," Gaman said.

Another recent study found that the quality of your marriage also affects weight gain; couples in happy marriages were found to pack on more pounds than those in unhappy marriages. Fitness magazine recommends being aware of how your eating habits have changed to match your spouse's and to make sure to get a workout in whenever possible.
