WHY IT'S KETO-FRIENDLY

  • Zero carbs: 0g net carbs keeps blood sugar and insulin low
  • High fat: ~14g fat per 100ml supports ketone production and satiety
  • MCT option: Medium-chain triglycerides are rapidly oxidized and can raise ketones
  • Stable energy: Caffeine + fat for a smoother lift vs. sugary coffee drinks
  • Appetite control: Helps extend fasting windows or reduce snacking
  • Convenient breakfast replacement (see considerations for protein/fiber needs)

HEALTH BENEFITS

  • Sustained energy: Fat provides long-lasting fuel alongside caffeine
  • May aid fat adaptation: High-fat profile complements ketogenic metabolism
  • Thermogenic effect: Caffeine can modestly increase energy expenditure
  • Fat-soluble vitamins: Grass-fed butter supplies vitamin A and small amounts of K2
  • Butyrate from ghee/butter may support gut lining health
  • Electrolyte-friendly: A pinch of salt can help hydration and performance on keto

PREPARATION SUGGESTIONS

SIMPLE BULLETPROOF

Blend hot black coffee with 1 Tbsp butter and 1 Tbsp MCT oil until frothy.

VANILLA VERSION

Add vanilla extract or cinnamon for flavor without carbs.

CREAMY UPGRADE

Add 50ml heavy cream for extra richness and fat (still near-zero carbs).

GHEE ALTERNATIVE

Use grass-fed ghee instead of butter for more butyrate and minimal lactose.

MCT EMPHASIS

Increase MCT oil gradually (start 1 tsp) for stronger ketone support.

MORNING RITUAL

Enjoy within 1–2 hours of waking for steady morning focus.
