I totally agree, calorie counting works. I tried WW before 3 times, it worked every time I did it, but I couldn't keep up with the points. WW is also based on calories, but they also include fat and fiber content to figure out "point" value for food. It got to be too much work and sometimes I couldn't find fiber or even fat content of some foods.
Calories are simpler in my eyes. Any diet plan requires work and dedication, you have to keep track of different aspects required by your specific plan, so the simpler the better.
I keep a daily journal on a notebook. I use different websites to find out calories for different foods, Calorieking.com, Dietfacts.com, this website also has a lot of calories for food. I think Fitday and Dailyplate are great tools, but for me personally I find it easier to have my little notebook handy. I write on it whenever I want and don't have to be near a computer for that. That's just what works for me. You could even use Excel and do it that way. I also bought the Calorie King book, it's a small book with thousands of foods and restaurants listed. It's pretty handy and small enough if you want to carry it around with you.
I started mid Jan and I've lost 18 lbs and I feel this is something I can do forever. And like previous posts say, the more you do it, the easier it gets. There are certain foods I know the calorie count by heart now b/c I eat them so often.
