WHY IT'S KETO-FRIENDLY
- This item contains the nutrients or compounds listed above; evidence for specific health outcomes depends on dose, preparation, and individual context.
- 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)
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.
