EVERYTHING YOU DO BURNS CALORIES! But some activities obviously burn more!!!!
So before you decide to sit on your ass all day on tumblr, think about this, standing burns about 50% more calories then sitting, so when you are blogging for hours on end, stand up every once in a while for like 10 mins! Take a walk around your room, anything!
Also cleaning, making the bed and doing washing are all small things that burn more calories then sitting on your ass, so keep your room clean and stay on top of your washing! Because honestly it is 5 mins of more calories burned, which could earn you a cookie, or an extra piece of chocolate or a better stomach!
