I watched a documentary on Meth use the other evening and the thing that makes this drug so addicting is the dopamine it releases in the brain..... (stick with me for a minute)...... dopamine is naturally produced in the brain and it is what gives us a feeling of well-being, happiness, etc. Lack of dopamine causes depression, cravings, etc. So anyway, I thought I'd go searching for natural ways to keep dopamine at the correct level in our bodies and found that the 17-day diet really supports most of the foods that naturally increase or regulate dopamine levels. So, if your going from high fat, processed, sugery, and high colesterol foods to the 17-day diet, then prepare to be "happy"!!! It will take alittle bit of time for your body to regulate to your new healthy diet, but then it's not just the weight loss that you will be elated by. Good luck with your new lifestyle.
