Still, ketosis isn't necessarily a bad thing, and it's a state that a lot of athletes, such as marathon runners, enter when they run out of glycogen supplies, and low-carb dieters often try to trigger ketosis in their body to assist weight loss.

In small doses, like during intermittent fasting, ketosis can have benefits for our bodies.
