How To Lose Weight For Your Wedding—The Healthy Way

Be prepared, Flipse says. Have the healthy food and snacks you'll need throughout the day at your disposal: whole grains, low-fat dairy, lean protein, an abundance of fruits and veggies, even a healthy frozen dinner for lunch.

5. It's OK if you slip up. You will have drinks, potato skins and chicken wings when you're out with the girls, Flipse says. When you realize how "bad" you've been, stop. The next thing you eat still counts. Compensate throughout the day to minimize damage. A croissant followed by salad, fish and steamed veggies is still a pretty decent day.

6. Don't diet at all! Buy the dress too big, Naylor says. This gives seamstresses room to create the hang that best flatters you and makes you look even thinner. If you buy too small and they have to put in an extra panel, it ruins the dress and they charge extra.

7. If all else fails…Photoshop. Or let the camera do the work. Some digital cameras have a "slimming" feature that shaves off just a tiny bit, Naylor says. No one will ever know.
