Well, different people will have different BMR and different daily / eating habits. I agree with you that many people are busy with daily work but ignoring the importance to eating healthily. People still eat when they are hungry, many choose to eat just to fill the hunger due to busy tasks. And only start worrying when health issues occurred which has accumulated for some time. Human body has the natural healing power if you provide it with the right ingredients, you are what you eat. Many health issues can be improved when people start to pay attention on this area.
