I'm not doing it to lose weight. I'm a male and I weigh 140lbs. I'm doing it because I've read that calorie restriction can help up-regulate your dopamine receptors and increase their density. I have terrible ADD and social anxiety and I believe a lack of dopamine and dopamine receptors is the cause of that. Will I be doing significant harm to myself by going on such a low calorie diet even if I eat lots of nutrient dense primal foods like organ meats, sardines, kale, etc ?
