As the New Year begins and resolutions are proclaimed, it's usually time to bring out the fad books, hop on a one-week juice fast, and fail after two days. But when it comes to serious weight loss, many people are swapping their regular holiday for a weight loss vacation. By cutting off distractions to everyday life and work, these trips offer individualized fitness and diet plans intended to last well beyond a week or two. Today's best weight loss vacations offer fitness adventure, spa detoxing, or medical programs to help people reach their weight loss goals through good food, engaged activities and proven medical advice.
