Yes. As a devoted calories counter, part of the reason it works is because it encourages you to pick--surprise!--foods that are lower in calories, which tend--surprise!--to be healthier and more nutrient-rich. I actually used to have fun figuring out what foods/cooking methods gave me the most bang for my buck, so to speak, which meant I automatically ate more grilled or baked lean meats and vegetables, and less bread and fried and/or sugary foods. The problem is fats don't understand how math, calories, or real food works, so end up doing things like a girl and her mom I knew in school, who I watched literally go through an entire box of fudgecicles in about an hour and a half because "they're only 100 calories each!" Yes, Chubs, and it's only 3:30 and you've just downed 600 calories worth of ice cream, on top of whatever you shoveled in earlier, and are you really going to eat a 200-calorie dinner and nothing else? No. You're not. And then you'll whine how "counting calories doesn't work." Just counting them isn't enough. You need to use that information to restrict your total calorie count.
