Which of the following is a consequence of consuming too few carbohydrates?

• A. Dehydration
• B. Weight gain
• C. Ketosis
• D. Hypoglycemia

Answer: (C)

When carbohydrate intake is too low, the body shifts from using glucose to burning fat for energy. The liver converts fatty acids into ketone bodies, which then circulate to provide fuel for tissues, including the brain. This rise in ketone bodies creates a metabolic state called ketosis, the result most directly linked to limited carbohydrate availability. Dehydration can occur with glycogen loss and diuresis, but the defining consequence of low carbs is ketosis, while weight changes and hypoglycemia depend on broader factors like total calories and individual physiology.
