Your weight is a balancing act, and calories are part of that equation. Fad diets may promise you that counting carbs or eating a mountain of grapefruit will make the pounds drop off. But when it comes to weight loss, it’s calories that count. Weight loss comes down to burning more calories that you take in. You can do that by reducing extra calories from food and beverages and increasing calories burned through physical activity.

But there are plenty of small but powerful, changes you can make that do add up to lasting weight loss success. The key is to create a plan that provides plenty of enjoyable choices, avoid common dieting pitfalls, and learn how to develop a healthier, more satisfying relationship with food.

Once you understand that equation, you’re ready to set your weight-loss goals and make a plan for reaching them. Remember, you don’t have to do it alone. Talk to your doctor, family and friends for support. Also, plan smart: Anticipate how you’ll handle situations that challenge your resolve and the inevitable minor setbacks.

If you have serious health problems because of your weight, your doctor may suggest weight-loss surgery or medications for you. In this case, you and your doctor will need to thoroughly discuss the potential benefits and the possible risks.

But don’t forget the bottom line: The key to successful weight loss is a commitment to making permanent changes in your diet and exercise habits.
