Additional Information

If your efforts to lose weight thus far have been thwarted, there could be a simple, physiological reason: low levels of serotonin. There is significant evidence to suggest that people who suffer from even a slight imbalance in bodily serotonin levels may experience negative mood states, poor quality sleep, stronger-than-normal appetite, and increased food cravings.
