Geeks don’t like gymming, running, swimming,etc. But that’s not the only way to burn calories. Incorporating more NEAT activities into your day, also known as non-exercise activity, can also help.
Studies show that lean people fidget for about 150 minutes a day more than obese people do. That kind of low-grade activity (tapping feet and fingers, twirling hair, gesturing while speaking, etc.) can burn 350 calories a day, which translates into 10-30 pounds a year! It's called Non-Exercise Activity Thermogenesis (NEAT), which is basically any movement that isn't intended as exercise. You can burn an extra 100-150 calories an hour by increasing NEAT.
