However, this diet is gaining considerable attention as a potential weight-loss strategy due to the low-carb diet craze, which started in the 1970s with the Atkins diet (a very low-carbohydrate, high-protein diet, which was a commercial success and popularized low-carb diets to a new level). Today, other low-carb diets including the Paleo, South Beach, and Dukan diets are all high in protein but moderate in fat. In contrast, the ketogenic diet is distinctive for its exceptionally high-fat content, typically 70% to 80%, though with only a moderate intake of protein.
I have never tried a keto diet (don’t like the idea myself) but I am what you could call moderately (or “liberal”) low carb. Around 125g max net per day, which as you likely know is half the RDA of 250g. I get most of the rest of my energy from protein and some for fat. The RDA of protein, around 50g, is only just enough to sustain muscle of a sedentary or low movement individual – and this is proven by the fact that a lot of people who hit the gym eat easily 2-3x the RDA of protein.
