Weight loss should be thought of as a path to overall wellness. I encourage you to focus on eating for long-term health rather than short-term weight loss, and pay more attention to the portion sizes of the food you eat rather than the calories. Counting calories, carbs, or fat grams is discouraged because the traditional method of doing this does not take into account the nutrient density of the food. 100 calories from an apple is not the same as 100 calories from a candy bar or a cookie. The apple contains fiber, nutrients, and enzymes, cleanses the body and helps keep it lean. The candy bar contains no fiber, nutrients or enzymes; in fact it robs the body of nutrients, upsets body chemistry, makes you feel hungry an hour later, and makes you fat.
When you improve the quality of the foods you eat and eat them in the proper quantities, there is no need to count calories. For another good explanation about how calories are used in the body, see a previous posting here on the message board titled "Calories vs. Weight". In my reply to that posting, I explain how calories are used in the body, and why counting calories is really kind of a misguided way of managing what you eat. You really should be more concerned with how much you eat. You should especially be eating far more vegetable portions than any other food group. I always tell my clients and students, "the amount of weight you lose is directly proportional to how many servings of vegetables you eat." You should be eating a minimum of 4 cups of vegetables every day, and several servings each day should be the dark green leafy types, such as spinach, kale, chard, broccoli, cabbage, etc.
From my own personal experience, I did not count calories to lose weight. I measured my portions.
