Diet fads seem to test the limits of science since forever. I’m an ancient feathered dinosaur, and I’ve seen it all from the popcorn diet to the South Beach diet to the paleo diet to the ketogenic diet.
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. It was a US$66 billion market in the USA alone in 2017. Wait, maybe I should invent the Raptor Diet?
