Trick your Body by changing it up!

I believe and have read that if you change the amount of calories you consume every day, you can lose weight, so say on one day you eat 2000 calories, the next day you eat 1400, next day you eat 1700... and so on.. your body doesn't get lazy and neither does your metabolism because it is contently readjusting to burning the amount you have consumed. So you are kind of tricking your body... Try this!
