Ketosis may occur during which dietary pattern?

• A. High-carbohydrate diets
• B. High-protein diets with normal carbs
• C. Frequent meals with balanced macros
• D. Very-low-carbohydrate diets

Answer: (D)

Ketosis happens when carbohydrate intake is very low, so the body switches from using glucose to burning fat for energy and produces ketone bodies in the liver. In very-low-carbohydrate diets, glucose is scarce, insulin stays low, and lipolysis increases, flooding the liver with fatty acids that are converted into ketones for fuel. The other patterns keep more carbohydrate available, maintaining glucose and insulin levels that suppress ketone production, or provide a steady energy mix that doesn’t drive the body into a ketotic state. So ketosis is linked to restricting carbs severely rather than relying on proteins, normal-carb intake, or frequent balanced meals.
