The Feed-fast Cycle Quiz! Trivia

Do you know anything about the fast feed cycle? The well-fed state begins immediately after finishing a meal. The digestion process starts in the mouth, where saliva starts to break the food down. The broken-down parts give nutrients to the blood. When fasting, blood sugar is low, and there won’t be much energy to use because carbohydrates fuel your brain. This quiz will give you more insight into the fast feed cycle.
