Dopamine fasting may be the newest wellness trend in Silicon Valley, but is there any evidence to back up this nerdy-sounding fad?

According to a news website, extreme practitioners of the “dopamine fast” abstain from anything that makes them feel good, such as eating, exercise, social media, video games, and conversation, but are not limited to any of these. Another news website reports that some people will even go so far as to avoid making eye contact, talking to friends, and even moving their bodies rather quickly. By abstaining from small pleasures, fasting attempts to “reset” the reward system in the brain, which is partially programmed by the neurotransmitter dopamine. People reportedly feel more focused and like the tasks, they had avoided more. Patients suddenly become reacquainted with themselves without screens or other distractions, claims Dr. Anna Lembke, associate professor and medical director of addiction medicine at Stanford University.

It is not meant to produce any form of mental problems or to lower dopamine levels. Contrarily, those who go on dopamine fast spend less time engaging in bad conduct. Thankfully, you can’t completely “fast” or eliminate dopamine from your body through dietary or lifestyle changes because doing so would likely have negative effects.
