“I know why I got fat. I eat too much and donât burn off enough calories. And, I donât have to read a book to know this.”
You have just repeated the common myth. There is a very good reason why you failed to burn the calories and stored them as fat, and is far from being just a sedentary lifestyle. See the video.
Same for when I worked in a meat packing plant after getting out of the Army and drinking beer every night for 2.5 months. In three weeks the extra weight was gone.
Nothing gets rid of fat like hard work and sweat.
