The real fad diet is USDA's food pyramid that thrust complex carbs down our throats in general and Senator Mcgovern's dogmatic war on fat that has resulted in many health issues over the past 30+ years.
You know how out upside down diet came about" A labor reporter cobbed them up and ultimately a panel voted on them despite broad disagreement but ultimately, the food producers got their way
"Concerns that were raised with the first dietary recommendations 30 y ago have yet to be adequately addressed. The initial Dietary Goals for Americans (1977) proposed increases in carbohydrate intake and decreases in fat, saturated fat, cholesterol, and salt consumption that are carried further in the 2010 Dietary Guidelines Advisory Committee (DGAC) Report. Important aspects of these recommendations remain unproven, yet a dietary shift in this direction has already taken place even as overweight/obesity and diabetes have increased. "
