Your liver makes its own sugar when you don’t eat carbs for a long time, and this process doesn’t hurt your liver or cause damage.

Eating fewer carbs might make your liver produce more sugar, and some scientists think this could put extra strain on your liver.

When you're under sudden stress, your liver quickly makes more sugar and releases it into your blood so your muscles have extra energy to react.

When rats eat a diet high in fat and low in carbs, their livers start making more sugar from lactate but get worse at breaking down an amino acid called alanine — especially if they're also eating fewer calories.

Even when rats eat fewer calories, a keto-like diet can still cause liver problems — like making too much sugar and messing up how the body uses protein — so the weight loss might not be worth the harm.
