On average, adults need about…

2000 calories a day, and it’s because we, on the average “burn” about 2000 calories a day.
Different activities require more fuel, the more strenuous – the more fuel, and less strenuous means less fuel needed – it’s a good rule of thumb.
Sitting quietly, “burns” 84 calories per hour, while walking “burns” 252.
So when you do the math – sitting quietly all day and night – we “burn” about 2016 calories.
So if you don’t want to cut calories from your diet, just knowing there is simple math going on that can help us “burn” more calories by upping our activity, is pretty sweet.
