In addition to making sure you don't wander in circles in the forest, the Instinct is a wellness tracker, keeping an eye on your steps, calories burned, stress levels (based on heart rate variability), and sleep quality. The Instinct has a 14 day battery life (or 16 hours with constant GPS monitoring), so you don't have to set it up on your nightstand every evening. Wear it to bed and it will track your REM sleep cycles and determine how restless you are during the night. There are even virtual fitness challenges that you enroll in from the Garmin Connect app to help keep you motivated.
To be honest, I ate to my heart's content on NY's eve right up to midnight. It was my final "give in to food temptation" before the old year ended. As a result of overeating and drinking caffeinated drinks, I was up from the stroke of midnight on NY's day until 5 a.m. During that span, I read numerous articles on lifestyle changes and short term diet challenges. All that reading led me to this site, for which I'm so thankful.
