Obesity: Hi, I assure you that a well balanced diet and decreasing your calorie intake (less calorie consumption than calorie burnt) and increasing physical activity cause weight loss. The problem usually is that we think we eat less but the fact is that we don't. keeping track of your calorie intake is helpful, use Myfitnesspal.com to do so. Also not all the foods are the same, you need to decrease Carb.
