Actually thinking about food is good if you keep the right perspective. You already know what type of foods caused you to gain weight. So focus on foods that will help you get healthier. I know it's not easy. I used to a very heavy meat & sweets eater. But that route led me to have excessive weight, high blood pressure, and bad health. Then I started focusing on foods that promotes good health, along with exercise, not just only lose weight. That route led me to have better health, normal blood pressure, and lose weight. In essence, your main focus on your diet is to be healthier first, and lose weight second. Trust me, if you work on the first part, the losing weight part will be sooooo much easier and will come naturally. So yea, think about food a lot. But try to focus on what's healthier for you instead worrying about what foods you miss eating. Take care
