High Fat Ketogenic Diet's Flashcards
What does cyanide inhibit?
The production of ATP.
What percentage of energy expenditure does the brain account for?
20%.
Where is glycogen stored in the body?
Liver and Muscles.
What are the two main ketones?
Acetoacetate (AcAc) and β-hydroxybutyrate (BHB).
What is the typical macronutrient ratio for a keto meal plan?
70% fats, 25% protein, 5% carbohydrates.
What is lipolysis?
The metabolic process where triglycerides are broken down into glycerol and fatty acids.
What is Beta Oxidation? Where does it occur?
Fatty Acids get broken down into acetyl coA, NADH, FADH2.
- Occurs in muscle cells and mitochondria.
What is the transition from Beta Oxidation to Ketogenesis?
When carbohydrate intake is low, excess asetyl coA from beta oxidation cannot enter krebs cycle due to limited oxaloacetate.
Acetyl coA diverts into ketogenesis.
What is Ketogensis? Where does it occur?
Acetyl coA is converted into ketone bodies Acetyl coA and HMG-CoA.
Serve as alternative energy sources.
- Occurs in the Liver.
What is Ketosis?
Metabolic state where body uses fats as primary energy source.
Causes elevated ketone levels.
Aids weight loss and provided energy for brain and muscles.
What is keto-adaptation?
Occurs when in nutritional ketosis over consecutive weeks.
What are the main positive impacts of ketogenic diets?
- Rapid weight loss
- Improved insulin sensitivity
- Reverse type 2 diabetes
What are the main misconceptions about fuel utilization?
the idea that the body can simply “switch” from carbohydrate to fat burning during exercise. In reality, both carbohydrate and fat metabolism occur simultaneously.
While it’s true that a higher percentage of fat is used during low-intensity exercise, this doesn’t mean more total fat is burned. Higher-intensity exercise often results in greater total calorie and fat expenditure.
