How this is calculated
total carbohydrate - fiber. Each published value is multiplied by your portion divided by the reference amount. No extra fiber, sugar alcohol or allulose deductions are applied here.
Grams and milliliters are not interchangeable. Household measures require a food-specific conversion; check your scale or product label.

WHY TO LIMIT IT ON KETO
- Incompatible with standard keto: very high net carbs per 100g
- This portion can exceed strict daily carb limits and may disrupt ketosis depending on portion and individual tolerance.
- Minimal fat and modest fiber—poor macro profile for keto
- One medium banana ≈24g net carbs, exceeding most daily limits
- This item contains the nutrients or compounds listed above; evidence for specific health outcomes depends on dose, preparation, and individual context.
- Use flavor workarounds: berries in moderation or banana extract (zero-carb)
PREPARATION SUGGESTIONS
SAVE FOR CARB-UP DAYS
Include bananas on cyclical keto/refeed days to replenish glycogen while intentionally leaving ketosis.
TARGETED POST-WORKOUT SNACK
This item contains the nutrients or compounds listed above; evidence for specific health outcomes depends on dose, preparation, and individual context.
TINY FLAVOR ACCENT
Blend a few thin slices (≤10g total) into a smoothie if metabolically flexible; count carbs precisely.
GREEN BANANA FLOUR
Adds resistant starch and prebiotic benefits in small amounts—still contributes carbs; not for strict keto.
BANANA EXTRACT
Add extract to keto desserts, pancakes, or shakes for banana flavor without sugar.
PRE-KETO TRANSITION
Use during tapering to lower carbs before fully committing to strict keto.
