WHY IT'S NOT KETO-FRIENDLY
- Very high sugar per volume: ~11–12g net carbs per 100ml rapidly elevates blood glucose/insulin
- Juicing strips fiber, leaving concentrated fructose that absorbs quickly
- A small 8 oz (240ml) serving ≈ 26–28g net carbs—more than many daily keto limits
- Minimal satiety and poor fat/protein balance for ketogenic macros
- Essentially a liquid sugar source—best avoided on keto
- Use zero-carb apple flavorings (extract/essence) or stick to water/sparkling water
HEALTH BENEFITS
- Provides vitamin C and small amounts of potassium
- Contains polyphenols (e.g., quercetin) with antioxidant activity
- Can contribute to hydration if diluted (though better keto options exist)
- Naturally free of fat and protein—consider context when not on keto
- May be useful strategically on planned carb-up or refeed days
- Whole-fruit alternatives retain fiber for slower absorption (still not keto-friendly)
PREPARATION SUGGESTIONS
AVOID COMPLETELY
Skip apple juice on keto—its carb density makes staying in ketosis difficult.
WHOLE APPLE ALTERNATIVE
If you must, a few thin slices of whole apple (with skin) provide flavor and some fiber—still not ideal for strict keto.
SUGAR-FREE SUBSTITUTE
Add apple extract or apple-flavored stevia to sparkling-water for zero-carb aroma and taste.
FLAVOR INFUSION
Warm water with cinnamon and a dash of vinegar-apple-cider to mimic cider-like notes without sugar.
