However, questions remain about what beverages are acceptable to drink during the fasting periods. One of the most common is: will lemon water break a fast? Understanding the impact of lemon water on your fast is key to getting the most out of this eating pattern.

So where does lemon water fit in? Can I drink water while fasting if lemon juice is added? Does lemon water spike insulin and break ketosis? Read on to learn the facts.
Does Lemon Water Break a Fast?
Will lemon water break a fast? The answer is maybe. Lemon water is unlikely to spike blood sugar or insulin levels, which is the primary concern with breaking a fast However, it comes down to how you make your lemon water.

If weight loss is your goal, this level of lemon water can potentially help fat burn. But, what about lemon slices? Floating thinly sliced lemon in your water seems harmless enough.

Does Lemon Water Burn Fat?

If simplifying food intake, promoting cell repair, or supporting metabolism are your main aims, then plain or purely unsweetened lemon water should not pose an obstacle. However, if maintaining very low insulin and achieving deep ketosis are critical, avoid adding lemon.
