Tag: Evening consumption

According to a study published in the *Journal of Clinical Sleep Medicine*, consuming 400 mg of caffeine six hours before bed can significantly disrupt sleep, reducing total sleep time by over an hour. This critical finding provides a clear answer to a common question: How late should I have an energy drink?

With caffeine proven to disrupt sleep for up to six hours after consumption, the critical question, "Can I drink bulletproof coffee in the evening while?" challenges its popularity. While often used as a morning energy kick and appetite suppressant, an evening cup can negatively impact sleep and overall diet effectiveness, particularly for those following a ketogenic or intermittent fasting protocol.
