To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
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.

getfit is great in that it is pretty satisfying to see how my physical activity measures up. It also prompts me to kick myself when the goals are not met. The different elements that allow the community to get to know MIT better (e.g., the tunnel walks) are pretty cool. It provides another avenue for me to connect with my friends, and I think getfit is a great program to enhance wellness at MIT.
