Obesity and type 2 diabetes are directly related to insulin levels and susceptibility. Any food raises insulin levels - but it does so in different ways. Carbohydrates give sharp jumps up and a long decline to normal. Fats smoothly raise and quickly lower this value. That is why calorie counting as such is ineffective if you want to lose weight or improve your body. We need to change habits. But food addictions that have sprouted on the basis of a certain pace of life are not so easy to change.
