Keto Diet Fundamentals and Core Concepts 4

Question 1

Which of the following foods is NOT compatible with a standard ketogenic diet?

Accepted Answer

Brown rice

Answer

Brown rice is a high-carbohydrate grain that would exceed daily carb limits on a ketogenic diet, making it incompatible with maintaining ketosis.

Question 2

What is 'keto-adaptation' (or 'fat adaptation')?

Accepted Answer

The body's long-term metabolic shift to efficiently burn fat and ketones as primary fuel

Answer

Keto-adaptation refers to the weeks-long process by which the body upregulates fat oxidation enzymes and mitochondrial capacity to efficiently use fat and ketones as primary energy sources.

Question 3

Which electrolyte is lost rapidly in the first days of a ketogenic diet due to decreased insulin and glycogen-bound water excretion?

Accepted Answer

Sodium

Answer

Insulin promotes sodium retention; when insulin drops on keto, the kidneys excrete more sodium (and water), which can cause electrolyte imbalances in the early phase.

Question 4

What is 'keto flu' and when does it typically occur?

Accepted Answer

Temporary symptoms (fatigue, headache, brain fog) in the first 1-2 weeks as the body adapts

Answer

Keto flu refers to a cluster of temporary symptoms including fatigue, headache, irritability, and brain fog that occur in the first 1-2 weeks due to electrolyte shifts and metabolic adaptation.

Question 5

On a ketogenic diet, which type of fat should make up the majority of caloric intake?

Accepted Answer

Mostly whole food fats like olive oil, avocado, nuts, and fatty fish

Answer

Healthy keto emphasizes whole food fat sources such as olive oil, avocados, nuts, seeds, and fatty fish rather than processed or industrially refined fats.
