The Nutrition Bar study tested the effects of eating a Nutrition Bar at breakfast time (after a 15-hour overnight fast), compared to either skipping breakfast or eating a standardized breakfast bar. The study looked at blood glucose and ketone levels over the 4-hour period after breakfast time and showed that blood glucose levels in patients eating Nutrition Bar were nearly identical to blood glucose levels in patients who skipped breakfast.
Ketone levels over the 4 hours were also very similar in both groups. These results showed that eating a Nutrition Bar doesn’t interfere with key physiological markers of fasting. The study also showed that Nutrition Bar gave people a feeling of being fuller and curbed the desire to eat for up to 3 hours after consumption. In other words, you can eat a Nutrition Bar to help make fasting easier and more pleasant, and maintain similar ketone and blood glucose levels as a water-only fast.
