Low-Carb and Cortisol Role
- Low-carb diets lead the liver to produce more glucose due to reduced dietary carbohydrates.
- Cortisol is one hormone that promotes glucose production but has broader impacts on the body.
Harmful Effects of High Cortisol
- Elevated cortisol can break down muscles and bones to supply amino acids for glucose creation.
- Prolonged high cortisol impairs immune system and fat storage, making it harmful long-term.
Protein Intake and Insulin
- In a study, people on a low-carb ketogenic diet ate twice as much protein but their insulin significantly dropped.
- Higher protein intake on low-carb doesn't necessarily spike insulin as once feared.
