Inefficient breathing reduces heart rate variability and interferes with the body’s natural gas exchange balance. Learn more.
- By weakening heart muscle contractions
10 Why can restricting carbohydrates on keto increase your risk of nutrient deficiencies?
- Protein intake crowds out all micronutrients
- Carbohydrate foods are the body’s main fuel
Eliminating fruits, vegetables, and whole grains removes key sources of B vitamins, fat-soluble vitamins, magnesium, and potassium. Learn more.
