I have a really high metabolism. Had it tested a year ago, and then again two weeks ago. Very high.it's because I move around constantly. Even though I sit in an office at work, I offset that by doing a workout in the morning and also an hour walk regardless of what I do in the workout, I always still do an hour walk in morning. Then at lunch I either do a light workout or a walk and in the evening no matter what has happened during the day or what is planned for the evening, I do another hour walk. I don't break speed records and I don't sweat during these walks but my metabolism is very high. So I dont care what anyone says, consistent MOVEMENT = high metabolism!!!
