High levels of activity burn lots of calories. The author of this blog post made a simple mistake: he thought that if he had big muscles, he would burn a lot of calories even when sitting still. That doesn’t happen. The only way to burn a lot of calories is to do a lot of physical activity. Edit to add: controlling diet is more effective than adding activity for most people in rich western societies because most of those people do not have the time, inclination, or opportunity to do a lot of hard physical activity every day.
