生酮饮食期间可以喝零度可乐吗？
摘要
Berg 博士通过分析零度可乐的成分表，探讨其是否与ketogenic diet相容。零度可乐中的关键人工甜味剂——阿斯巴甜和乙酰磺胺酸钾——使其在生酮饮食中存在问题，尽管它不含任何糖分。他的结论是明确建议不要饮用。
核心要点
- 零度可乐不适合生酮饮食，尽管不含糖
- 阿斯巴甜会促进insulin resistance，而这正是ketogenic diet所要纠正的状况
- **乙酰磺胺酸钾（Ace-K）**有可能像摄入普通糖一样升高血糖水平
- 饮料中不含实际糖分，并不意味着它自动适合生酮饮食
- 零度可乐中需要注意的成分包括：阿斯巴甜、乙酰磺胺酸钾、焦糖色素、磷酸、苯甲酸钾、柠檬酸和天然香料
详细内容
零度可乐成分解析
零度可乐包含以下成分：
- 碳酸水
- 焦糖色素
- 阿斯巴甜
- 乙酰磺胺酸钾（Ace-K）
- 磷酸
- 苯甲酸钾
- 天然香料
- 柠檬酸
- 咖啡因
为什么阿斯巴甜在生酮饮食中有问题
Berg 博士提出的核心问题是阿斯巴甜会促进insulin resistance。由于ketogenic diet的主要目标是逆转或减少insulin resistance——改善身体利用脂肪供能的能力——摄入阿斯巴甜会直接与这一目标相悖，无论其零卡路里或零糖分的属性如何。
为什么乙酰磺胺酸钾同样令人担忧
**乙酰磺胺酸钾（Ace-K）**被指出有可能将blood sugar水平提高到与摄入普通糖相当的程度。这意味着它可能触发insulin response，从而破坏生酮饮食所旨在实现的代谢状态。
“零糖”标签的核心问题
视频强调了一个重要区别：产品标注”零糖”或”无糖”并不意味着它与生酮饮食相容。用作糖替代品的人工甜味剂本身就可能干扰insulin sensitivity和blood glucose regulation，使其对遵循生酮或intermittent fasting方案的人群适得其反。

Can You Drink Coke Zero on a Keto Diet?
Summary
Dr. Berg addresses whether Coke Zero is compatible with a ketogenic diet by examining its ingredient list. The key artificial sweeteners in Coke Zero — aspartame and acesulfame potassium — make it problematic for keto, despite it containing zero sugar. His conclusion is a clear recommendation against consuming it.
Key Takeaways
- Coke Zero is not keto-friendly, despite containing no sugar
- Aspartame promotes insulin resistance, which is the very condition a ketogenic diet aims to correct
- Acesulfame potassium (Ace-K) has the potential to raise blood sugar levels similarly to consuming regular sugar
- The absence of actual sugar in a drink does not automatically make it safe for keto
- The ingredients to watch out for in Coke Zero include: aspartame, acesulfame potassium, caramel color, phosphoric acid, potassium benzoate, citric acid, and natural flavorings
Details
Coke Zero Ingredients Breakdown
Coke Zero contains the following ingredients:
- Carbonated water
- Caramel color
- Aspartame
- Acesulfame potassium (Ace-K)
- Phosphoric acid
- Potassium benzoate
- Natural flavorings
- Citric acid
- Caffeine
Why Aspartame Is Problematic on Keto
The central issue Dr. Berg raises is that aspartame promotes insulin resistance. Since the primary goal of a ketogenic diet is to reverse or reduce insulin resistance — improving the body’s ability to use fat for fuel — consuming aspartame directly works against that goal, regardless of its zero-calorie or zero-sugar status.
Why Acesulfame Potassium Is Also a Concern
Acesulfame potassium (Ace-K) is flagged as having the potential to raise blood sugar levels to a degree comparable to consuming regular sugar. This means it can trigger an insulin response, undermining the metabolic state that keto is designed to achieve.
The Core Problem with “Zero Sugar” Labels
The video highlights an important distinction: a product being labeled “zero sugar” or “diet” does not make it compatible with keto. The artificial sweeteners used as sugar substitutes can independently interfere with insulin sensitivity and blood glucose regulation, making them counterproductive for anyone following a ketogenic or intermittent fasting protocol.
