What is Keto?
Keto is a very low-carb way of eating. Depending on the individual it might range from 20-150 carbs per day.
By staying at a low number of carbs, people enter nutritional ketosis, a state in which their body is burning fat instead of carbs to generate energy. For many people, this allows them to lose weight while not needing to feel hungry. It also tends to improve various health markers, while increasing some cholesterol readings.
Before the last few decades, eating low-carb wasn't a weird diet, it was just how most people ate. I recall reading Michael Palin's biography where he discussed how for the 1979 film The Life of Brian he had to be very thin to play the beggar, so "no potatoes for me". Before the 1980s, it was common knowledge that carbs like potatoes would increase a person's weight.
On this site, Keto means cooking in a way that keeps carbs low while prioritizing real ingredients and flavor. When there are carbs, they are usually complex, high-quality and slower to enter your system.
There's a lot more to the story, and no one has all the answers, so if you're curious check out the links below for and against low-carb eating.
