Key insights

🍞Eating a high percentage of calories as carbohydrate does not mean 100% of energy will come from dietary carbohydrates.

🧠The brain can use ketones as a source of energy, indicating that it doesn't solely rely on glucose.

🍬Different sugars, such as glucose and fructose, have varying effects on blood sugar levels and liver health.

🍊Orange juice, despite being considered healthy, can significantly raise blood sugar levels due to its high sugar content.

Q&A

Can the brain function without glucose?

—The brain can use ketones as an alternative fuel source when glucose availability is limited.

Why is fructose considered worse than glucose?

—Fructose has a different metabolic pathway that can lead to a fatty liver and insulin resistance.

Are whole wheat products better for blood sugar control?

—Whole wheat products have a slightly lower glycemic index compared to refined sugars, but the difference is minimal.

Is it necessary to eat small frequent meals to maintain stable blood sugar?

—Frequent meals perpetuate carbohydrate dependency and unstable blood sugar levels. Intermittent fasting may be more beneficial.

Does age play a role in blood sugar control?

—Blood sugar problems can occur at any age due to lifestyle factors, such as poor dietary choices and lack of physical activity.
