The keto-diet is considered one of the most recognizable and, what is more important, the most studied diet. This diet has become one of the top 10 diets included in the Google report for 2019 for search queries. And according to the Reddit report for 2019, it became the most talked about diet trend in 2019. The r / keto sub-Reddit was the second wellness group in the world in 2019, which increased the number of subscribers by 65 percent compared to the previous year. There are two radically different positions in disputes about keto: there are people who are prone to a full lifestyle, and those who are absolutely not. Despite all the positive and negative reviews, you can still get a little confused about the details of the keto diet – for example, how it works, and how to calculate the amount of butter and cheese you eat.
