First of all, start early enough in advance to give yourself time to lose weight or tone up. Six months to a year is generally a reasonable time frame. Second, realize that planning a wedding will be stressful and involve a lot of food from cake tasting to dinner with the in-laws, so allow for splurges. If you want, work with a food delivery system like Sunfare that will bring nutritious meals to your home so you don't have to have the added stress of cooking food for yourself. Work with your body. Lastly, set a realistic goal weight. Each person has a weight range that is preset in their genes, find your ideal weight with this easy calculator.http://www.youtube.com/watch?v=7eOVy-eQbFI 

Your body will change as your workouts progress, especially your back muscles (latissimus dorsi and rear deltoids). These muscles tend to expand if you haven't been exercising them regularly. Make sure the person fitting your dress knows you plan on exercising more so he/ she doesn't take too much out at the beginning.http://www.youtube.com/watch?v=7eOVy-eQbFI 

Don't fall for the allure of the restrictive Hollywood diets you see featured on the covers of the tabloids. Weight-loss gimmicks may work for a month, but they're detrimental to your weight-loss goals in the end. Remember that they can photoshop those! Instead, follow a consistent, healthy weight-loss plan to achieve your desired results.http://www.youtube.com/watch?v=7eOVy-eQbFI
