New research showed men who consumed less than 40% of their total energy from carbohydrates experienced significantly higher risks of all-cause and cancer-related mortality
I'm a little surprised by how much incredulity there is in the comments here. It's amazing that anyone, let alone so many people right now, would think that taking away all the most protective foods (ie., plants in their whole, intact forms, which are almost invariably high carb), and in most cases replacing them with the very substances most strongly associated with our number one killers, cardiovascular disease and cancers, (ie., animal flesh, dairy, and insane amounts of saturated fats), and act surprised when it kills them faster.
I did a keto diet for about a year. Every meal was about 2/3 veggies. The problem with low carb diets is most people don't do them healthy. They see that certain things are listed as ok to eat and they just eat that and don't follow a balanced regimented diet.
