WHY TO LIMIT IT ON KETO
- Concentrated umami: a teaspoon goes a long way, keeping absolute carbs low
- Easy to dilute into broths/sauces for flavor with minimal quantity
- Pairs well with low-carb bases (cauliflower rice, shirataki noodles)
- Label-savvy choices (no added sugar) help minimize carb impact
- Works as a finishing ingredient—stir in off-heat to use less
- Naturally complements high-fat ingredients (butter, sesame oil) for better keto ratios
