I was having the same problem until I got an app called "My Fitness Pal" at the recommendation of a friend who used it to lose weight for her wedding. It keeps track of your food, calorie intake, calories burned, and exercise. What you do is put in your height, current weight, goal weight, how many pounds you want to lose per week, activity level, and it calculates how many calories you should eat, gives you nutritional goals, and minimal calorie burning goals per day. You can also sync a pedometer to it (I think most smartphones have a pedometer in them)and it will keep track of how many calories you have burned just from walking around all day. I have been using it for a week and I have lost 2 pounds already c:. It has helped me change the way I eat too, I pack my lunches now and eat more fruits and vegetables. You just have to be honest when you fill out your food and exercise dairy. And if there isn't a food that you have eaten in their database you can add it and your own food recipes. It works out well for me because I always have my phone on me anyway, it's free too.
