Spouse-proof your diet. DON'T VIEW FOOD AS ENTERTAINMENT. "For many couples, food is something to do," Sass says. "I see this all the time when couples make ordering Chinese food on a Friday night their main activity." To break this pattern, try planning outings where the focus isn't on eating, such as having a poker night with pals or seeing a comedy show.
EAT LIKE YOU DID BEFORE YOU WERE MARRIED. Since couples share more meals after getting hitched, and men tend to eat more than women, women often start munching extra calories unconsciously, says Hillary Baron Irwin, a registered dietitian in New York City. Aim to eat a palm-size portion of protein, a fist-size of whole grains and a half plate of veggies.
GET A MOVE ON. Working out together is a great motivator, says Lee Ross, president of Exude.com Fitness. "Exercising three to five times a week for 50 minutes is the best way to keep weight in check," Ross says. Join a health club that offers a deal when two people sigh up together. Or start biking and plan a weekend cycling trip. You'll get your heart rate up in more ways than one! SV
Don't ruin the togetherness with being competitive. Men have a tendency to lose weight faster.
