I'm watching a show on people that have decided to make serious changes to their diet, thinking it's healthy. Instead it's so extreme, it's likely to be unhealthy. One guy is 6 feet tall and weighs 118 pounds. He looks terrible. He's on a "calorie restricted" diet for longevity. Another guy is a "raw vegan". He thinks he's super healthy, yet they show him running, then crumpling to the ground in agonizing pain, and then passing out. What's wrong? Could it be his insanely restricted diet? How do people get sucked into these crazy diets? It's not that hard to find out what the body needs. I always love the people that restrict their diets to the point they can't live on food alone, and have to eat a bunch of processed "supplements", while spouting off about eating a 100% natural, unprocessed diet, then downing handfuls of pills or processed powders to keep them alive.
