It's a known fact that several [not all] couples gain weight once they get into a serious relationship. You may be asking yourself why, well it's pretty simple. Eating out, duh! While some people cook in, other's find it in their busy schedules to make every night a date night that includes pizza, pizza, tacos, pizza and oh yeah, more pizza.
While gaining weight may not always be a negative, making sure you two can work it out just as much as you can eat out is extremely important. Trust me, I've been there. Getting into a relationship and gaining a couple [or more than a couple pounds] is all fun and games until you're too lazy and out of breath to go on anymore dates to grab a bite to eat.
