If you're trying to lose those last 10 pounds, odds are you've tried to lose them before. Or you lost weight and gained it back. If that's you, it might be time to try these tips that have helped countless people lose a hundred pounds or more. Create a medically-sound diet and fitness plan. Dr. Victor Stevens is the senior investigator at the Kaiser Permanente Center for Health Research. He says you should always talk about your weight loss goals with your doctor, because they can provide you with a lot of time-tested information. Plus, if you're considering going on a diet that you think your doctor wouldn't approve of, it's probably a bad idea. Be accountable. In a study done by the American Diabetic Association, people who reported their progress to others on a regular basis lost six times more weight than those who didn't. You can start by asking a friend to exercise with you. Or ask them to simply check in with you a couple of times a week to see if you're hitting the gym, and making good food choices. *Adjust your expectations. Dr. Daniel Stettner teaches psychology at Wayne State University. He says that a lot of people sabotage themselves by trying to lose weight too quickly. Studies show that people who lose a pound a week are the most successful in keeping weight off. So, if you want to lose 30 pounds, thinking about an outfit you'd like to wear to a football game next fall is a better strategy than daydreaming about a wearing a bikini this summer.
