A new study of 800 nurses¹ found that those who snacked had higher stress, more cognitive failures at work, and more injuries outside of work.

I have long warned against snacking because it throws hormone switches involving insulin, leptin, and glucagon into a poor state of timing which will lower blood sugar in the brain improperly. Since your brain needs a stable supply of blood sugar for optimal function, a disruption in this process is certain to impact cognitive ability which is demonstrated by this study.

You are supposed to get a snack between meals – but it is supposed to come from your liver! The moral of the story is to eat in harmony with leptin or suffer the consequences.
