Hypoglycemia
Which of the following is a primary mechanism for weight reduction in a ketogenic diet?

Why is moderate protein intake crucial in a ketogenic diet?
To prevent muscle protein from converting to glucose
What alternative source of energy does the brain utilize in a ketogenic diet?
Ketone bodies
Study Notes
Nonpathological Forms of Ketosis
- Ketosis occurs when the body is fed a high-fat, low-carbohydrate diet or after severe exercise.
- Excess formation of acetoacetate and 3-hydroxybutyrate, both moderately strong acids, can lead to ketoacidosis, a potentially fatal condition, especially in uncontrolled diabetes mellitus.
Keto Diet (Ketogenic Diet)
- The ketogenic diet is a low-carbohydrate, moderate-protein, high-fat diet that induces ketosis without ketoacidosis.
- This diet can be used for weight reduction without compromising overall health.
Mechanism for Weight Reduction
- A low-carbohydrate diet triggers the body to burn stored fat (lipolysis) for energy.
- Reduced insulin secretion due to hypoglycemia (low blood sugar) reduces lipogenesis (fat storage).
- Increased glucagon secretion due to hypoglycemia stimulates lipolysis (fat breakdown).
Mechanism for Preserving Body Health
- Moderate protein in the ketogenic diet preserves lean body mass, including muscles, without excess protein conversion to glucose.
- Ketone bodies produced in the ketogenic diet serve as an alternative source of brain energy, mitigating the negative effects of low glucose levels on the brain.
