Seems like we get a new study that tells us certain things are good for us, then a few months later we get another study that says the previously good thing is now bad for us. The latest previously healthy thing that is now not so healthy is low-carb diets and that includes keto diets.
According to a massive new study published in The Lancet Public Health, “low carbohydrate diets, which restrict carbohydrate in favor of increased protein or fat intake,” could slash years off your life.
Me after reading the good news that carbs have finally been vindicated.

The huge study tracked over 15,000 people in the U.S. over 25 years and their dietary habits. Participants filled out questionnaires detailing what foods they ate. The study did not include extreme cases such as anyone eating less than 600 calories or more than 4,200 calories.
The researchers of the study also consulted data from seven other studies involving over 400,000 people in 20 countries.
The study found that people who consumed a low-carb diet and a high-carb diet died earlier than those who consumed a medium amount of carbohydrates. Researchers found that 50-year-olds who consumed a moderate amount of carbohydrates, which is categorized as receiving 50% – 55% of your energy from carbs, were on average expected to live for another 33 years.
Individuals who were on extra-low-carb diets, which is anyone who got 30% or less of their energy from carbs, were expected to die four years earlier on average. Low-carb diets, which is considered 30%-40% of energy from carbs, led to a death that was 2.3 years premature and those on a high-carb diet, 70% or more of energy from carbs, were predicted to dies 1.1 years earlier.

This could spell horrible news for those on a ketogenic diet since their diet would be considered to be in the extra-low-carb diet category. Keto diets typically recommend that you don’t get more than 5% of your energy from carbs.
There was one caveat to the keto diet and this study. Those who engaged in a low-carb diet who consumed plant proteins and nuts instead of meat and dairy had a slightly reduced risk of mortality.
Unfortunately, the scientists stress that your carbs should be coming from fruits and vegetables, not processed or sugary foods. So that means that you shouldn’t be eating this double bread bowl stuffed with mac and cheese or scarfing down donuts.
