The keto diet, explained

The "metabolic advantage" hypothesis

Advocates of ketogenic diets for weight loss claim that ketogenesis can lead to burning 10 times more fat and an extra 400 to 600 calories per day.

This might sound great, but what’s often lost in all the boosterism is that this is still just a hypothesis.

Ketosis
... is a natural process the body initiates to help us survive when food intake is low. During this state, we produce ketones, which are produced from the breakdown of fats in the liver.

The end goal of a properly maintained keto diet is to force your body into this metabolic state

The Keto diet - documented uses

The keto diet is primarily used to help reduce the frequency of epileptic seizures in children. While it also has been tried for weight loss, only short-term results have been studied, and the results have been mixed. We don't know if it works in the long term, nor whether it's safe.

Ketogenic diet

Unlike other low-carb diets, which focus on protein, a keto plan centers on fat, which supplies as much as 90% of daily calories. The keto diet aims to force your body into using a different type of fuel. Instead of relying on sugar (glucose) that comes from carbohydrates (such as grains, legumes, vegetables, and fruits), the keto diet relies on ketone bodies, a type of fuel that the liver produces from stored fat. 

Keto diet meals

Followers must eat fat at each meal:

  • Some healthy unsaturated fats are allowed: almonds, walnuts, seeds, avocados, tofu, and olive oil. But saturated fats from oils (palm, coconut), lard, butter, and cocoa butter are encouraged in high amounts.
  • Protein is part of the keto diet, but it doesn't typically discriminate between lean protein foods and protein sources high in saturated fat such as beef, pork, and bacon.
  • You can have certain fruits (usually berries) in small portions. Vegetables are restricted to leafy greens (kale, Swiss chard, spinach), cauliflower, broccoli, Brussels sprouts, asparagus, bell peppers, onions, garlic, mushrooms, cucumber, celery, and summer squashes. 
The general Keto diet
The general Keto diet

The Keto diet is one of the biggest diet phenomenons today. It is the most Googled diet of 2018 and has surpassed Weight Watchers and other low-carb regimens, Atkins and Paleo.

There is a considerable variation in how humans respond to nutritional and dietary tweaks in this overhyped craze, but not without merit. There is a growing body of science exploring keto as a potential thwart for Type 2 diabetes and other illnesses.

Keto is a no-carb diet

Carbohydrates account for about half the calories on average in the American diet. Rice, maize, and wheat provide 60 percent of the world's food energy intake, even though there are more than 50,000 edible plants.

Keto is practically no-carb, forbidding processed junk foods and severely limits grains, including whole grains, fruits, and legumes such as brown rice, apples, and lentils. Keto adherents think conventional nutritional wisdom is harmful.

Keto is a cultural identity

Keto is more than just a diet. It is a cultural identity.

The Keto diet changes how adherents think about medicine and nutrition. With the fake news that dominates the news cycle, it's not surprising that keto went viral. It's anti-establishment.
