Some people think that ketosis is extremely dangerous.
However, they might be confusing ketosis with ketoacidosis, which is completely different.
While ketoacidosis is a serious condition caused by uncontrolled diabetes, ketosis is a natural metobolic state.
In fact, ketosis and ketogenic diets have been studied extensively and shown to have major benefits for weight loss (1,2).
Ketogenic diets have also been shown to have therapeutic effects in epilepsy, type 2 diabetes and several other chronic conditions (3, 4, 5, 6).
Ketosis is generally considered to be safe for most people. However, it may lead to a few side effects, especially in the beginning.
An Overview of Ketosis
First, it’s necessary to understand what ketosis is.
Ketosis is a natural part of metabolism. It happens either when carbohydrate intake is very low (such as on a ketogenic diet), or when you haven’t eaten for a long time.
Both of these lead to reduced insulin levels, which causes a lot of fat to be released from your fat cells. When this happens, the liver gets flooded with fat, which turns a large part of it into ketones.
During ketosis, many parts of your body are burning ketones for energy instead of carbs. This includes a large part of the brain.
However, this doesn’t happen instantly. It takes your body and brain some time to “adapt” to burning fat and ketones instead of carbs.
During this adaptation phase, you may experience some temporary side effects. These are generally referred to as the “low-carb flu” or “keto flu.”
