The Science Behind Ketosis

Ketosis is more than just a diet trend—it's a natural metabolic state that humans have relied on for survival throughout history.

What Happens in Ketosis?

When you restrict carbohydrates, your body goes through several changes:

1. Glycogen Depletion (Days 1-2)

   • Your liver stores about 100g of glycogen
   • This is used up within 24-48 hours of carb restriction

2. Gluconeogenesis (Days 2-3)

   • Your body starts making glucose from protein
   • This is a temporary bridge phase

3. Ketogenesis (Days 3-7)

   • The liver begins converting fatty acids into ketones
   • These become your primary fuel source

Types of Ketones

Your body produces three types of ketone bodies:

Benefits of Ketosis

Brain Health

Ketones provide 70% of the brain's energy needs and may protect against neurodegenerative diseases.

Weight Loss

Fat becomes your primary fuel, leading to efficient fat burning.

Stable Energy

No more blood sugar crashes or afternoon slumps.

Conclusion

Understanding the science helps you appreciate why keto works and motivates you to stay committed.
