As an ancient dinosaur, I’ve seen every diet fad from the popcorn diet to the South Beach diet to the paleo diet to the keto diet. Most of these fads are based on almost no good science, though they try to bring really bad science to convince themselves or others to “buy” into it, sometimes literally.
I’m sure that the ancient Romans had some diet fad diet that the aristocracy followed to keep themselves healthy – oh wait, the Roman upper class followed the Mediterranean diet, which may be one diet fad that stood the test of time and science.
Outside of the aforementioned Mediterranean diet, which includes whole grains, olive oil, seafood, legumes, and nuts, most of these diets lack robust scientific evidence supporting their usefulness in weight loss or maintaining some unbiased standard of health. But they certainly make a lot of money for those promoting them. The worldwide diet management market is estimated to be over $192 billion in 2019. Wait, what? Obviously, I’m in the wrong business.
One of the current fads is the keto diet, which is all the rage among those looking to lose weight, improve their health, and, I’m sure, prevent cancer. Before someone thinks it really prevents cancer, it does not. In fact, it may increase the risk of cancer. But that’s another story for another day.
Let’s get into this keto diet fad. Is it supported by any robust, repeated, published evidence? Or, like most diet fads, is it mostly supported by testimony and anecdotes?Continue reading “Keto diet – what does the scientific evidence say about its effectiveness?”
