Your brain could suffer too
Overeating might impair brain functions, especially if you’re a bit older. Overweight and excess calories can lead to memory loss, mental decline and cognitive loss.
Eating too much in a single sitting can lead to a sugar spike in your bloodstream that your brain won’t take very well; you might feel lightheaded and sluggish.
If you were to eat this way every day, you wouldn’t last more than a few years before having serious chances of dying. That’s no joke. Your body is a complex machine and you must take care of it.
