You maintain your weight by consuming the right amount of calories, gain weight with larger amounts, and lose weight with a lesser amount. Your calorie needs are determined by your age, height, weight, gender, and activity level. You can use the Harris-Benedict Equation or the Mifflin-St. Jeor equation to calculate the number of maintenance calories you require. The Mifflin-St. Jeor calculation is best for someone who is overweight or obese. Once you know how many calories you need to maintain your weight, you can determine what it will take to lose or gain weight. When you go above or below your maintenance calories by 3,500 calories, you will either gain or lose 1 pound. For example, if you consumed an extra 500 calories per day, you would gain 1 pound in a week (500 x 7 = 3,500). The same is true for weight loss. This is why every calorie counts when it comes to your weight.
The next time that you are about to decide what to eat remember that "it's what's inside that counts." You can take a look inside by reading what is on the outside, or the food label. The food label, or nutrition facts label, is your best source of information for what you are feeding your body. Before you can use it, you have to know how to read it, so let's "digest" the food label.

Due to the complexity of analyzing diets, the DRIs have been primarily used by researchers and registered dietitians. The programs used to analyze diets have now become available to the public. You can keep track of everything that you eat and drink on one of the internet sites that offer one of these programs, and you will get detailed information about your intake in comparison to the DRIs. When keeping track of your diet, you want to use a Web site that uses the USDA National Nutrient Database for Standard Reference as their source of nutrition information.
At the same time, Turoff tells her clients to proceed with caution when you have a green juice because it is not as satisfying as eating your vegetables due to the lack of fiber. “A big salad will be a lot more filling,” she says. If you do have a green juice, check the ingredient list to make sure it’s not loaded with fruit, which can send the drink’s sugar count soaring, she notes.
Focus on exercise: In a 2008 study in Obstetrics & Gynecology, almost 30 percent of women reported that they had experienced low libido in the past year. “Exercise is one of the best ways to improve body image, which affects libido,” says Heather Hausenblas, an associate professor of health sciences at Jacksonville University, in Florida, whose research focuses on exercise and body image. Libido is also affected by mood and self-esteem, and exercise can improve both.

The plan promotes long-lasting, sustainable changes, and undoubtedly a bounty of research backs this up. In fact, one December 2013 study in the American Journal of Medicine shows that people following Weight Watchers were close to nine times more likely to lose 10 percent of their body weight, compared to people following a self-help diet plan.

If you're losing weight but not as fast as you'd like, don't get discouraged. Dropping pounds takes time, just like gaining them did. Experts suggest setting a realistic weight loss goal of about one to two pounds a week. If you set your expectations too high, you may give up when you don’t lose weight fast enough. Remember, you start seeing health benefits when you've lost just 5%-10% of your body weight.
