I suppose naturally fat free foods are just fine. It's when they try to make them taste like something that has fat in it, they screw it up. And yeah, fat free cheese is like plastic--except fat free cheese doesn't melt and plastic does!
The bolded requires more nuance to understand that that it's not necessarily accurate, medical situations like yours aside. As far as the standard American diet where almost 75% of calories consumed are highly processed foods with about a third of those calories coming from fats that are not found in nature naturally, and the fact that people continue to consume too many calories to begin with fueled the war on fat and the fact they represent 9 calories per gram was a no brainer for the food manufacturers to perpetuate and help continue to sell more low fat processed foods, or just enough fat to make you want to continue to purchasing those products which in manufacturing lingo is called the "bliss point". Consuming these types of fats along with refined grains and sugar in excess is extremely unhealthy, would be an understatement and it's making most western populations very very sick. Basically there's a lot more to it than too much fat is bad.
