YES - AMAZINGLY, WHEN YOU EAT FAST BAR, YOUR BODY THINKS IT’S STILL FASTING*

Fast Bar’s proprietary formula of premium ingredients doesn’t trigger your body’s nutrient-sensing system, so your body’s tricked into thinking it’s fasting. It's the only thing you can eat during your fasting window without breaking your fast — eat without your body even knowing it.
*In a randomized, controlled study of 105 adults, participants fasted overnight for 15 hours, then had either breakfast, a Fast Bar, or water. Blood glucose and ketones were measured every hour for 4 hours with results shown above. Data on file.
