When it comes to fasting, there are different types of fasts, some of which allow for the consumption of certain beverages such as water, tea, and coffee, while others require complete abstinence from all food and drink.

Does Lemon Juice Have Calories – Nutritional Profile

With the rise of health trends, many people are now looking to substitute certain ingredients in their diets or recipes to maintain a healthy lifestyle. 

  • One tablespoon of lemon juice (approximately 15 mL) contains only 3-4 calories.

One such ingredient that is frequently used is lemon juice. While the tart taste of lemon may add some delicious flavor to dishes, those curious about their health might ask: does lemon juice have calories? The answer isโ€”yes! 

Lemon juice is a good source of several essential vitamins and minerals. Here is a breakdown of the nutritional profile of one tablespoon (approximately 15 mL) of lemon juice:

  • Calories: 3-4
  • Carbohydrates: 1 gram
  • Fiber: Less than 1 gram
  • Protein: Less than 1 gram
  • Fat: Less than 1 gram

Vitamins and minerals:

  • Vitamin C: 6% of the recommended daily value (RDV)
  • Folate: 1% of the RDV
  • Potassium: 1% of the RDV
  • Vitamin B6: 1% of the RDV

Lemon juice also contains small amounts of other nutrients, such as calcium, iron, magnesium, and zinc.

In addition to its nutritional profile, lemon juice contains citric acid, giving it a sour taste. Some people believe that citric acid may have health benefits, such as improving digestion and reducing the risk of kidney stones. However, more research is needed to understand these potential benefits fully.

Overall, lemon juice can be a healthy addition to a diet in moderation, but it should not be relied upon as a sole source of nutrition.

While it does not pack as much caloric content as most other ingredients and can even be viewed as an alternative for other high-calorie condiments due to its sour taste, a single tablespoon of freshly squeezed lemon juice contains approximately three and a half calories. 

This goes to say that although it has significantly fewer calories than other items used in the kitchen, you must still consider any calorie consumption when aiming for maximum health.

Can I Drink Lemon Water During Intermittent Fasting?

One common question about this practice revolves around the consumption of lemon water during a fasted state. Although the answer depends on your specific intermittent fasting protocol and goals, having limited amounts of lemon water can support the body without negatively impacting the results of their diet. 

There are several different types of intermittent fasting, but the most common ones are time-restricted feeding, alternate-day fasting, and 5:2 fasting.

Time-restricted feeding

Time-restricted feeding is intermittent fasting, where you eat only during a specific time window each day and fast for the rest of the day. During fasting, you can consume water, tea, and coffee, but avoid calorie-containing beverages, including lemon water.

Alternate-day fasting

Alternate-day fasting involves fasting every other day, while on feeding days, you can consume water, tea, coffee, and low-calorie beverages. Still, again, you should avoid any calorie-containing drinks, including lemon water.

5:2 Fasting

5:2 fasting involves eating normally 5 days a week and reducing calorie intake to about 500-600 calories for 2 non-consecutive days. You can consume calorie-free beverages on the 2 reduced-calorie days, such as water, tea, coffee, and lemon water.

In summary, if you are doing a type of intermittent fasting that allows for the consumption of calorie-free beverages during the fasting period, such as time-restricted feeding or 5:2 fasting, then you can drink lemon water during the fasting period. 

However, suppose you are doing intermittent fasting that requires complete abstinence from all food and drink, such as alternate-day fasting. In that case, you should not consume any calorie-containing beverages, including lemon water.

The Real Deal on Does Lemon Juice Break a Fast

Regarding fasting, the question of whether or not lemon juice breaks a fast comes up a lot. After all, lemons are natural – and therefore, how could consuming the juice do any harm? But, unfortunately, the answer is more complex. 

As popular understanding suggests, lemon juice is considered okay while fasting since its main components are vitamins, minerals, and antioxidants rather than carbohydrates.

However, some healthcare professionals suggest not adding any “extra” ingredients to your fast and instead restricting your diet to water only to get the most resounding benefits from your fast. Ultimately it’s best to talk with a nutrition professional about whether or not consuming lemon juice during a fast is an appropriate choice for you.

Does Lemon Water in the Morning Break a Fast?

An increasingly popular trend in health routines is drinking lemon water in the morning, but whether it breaks a fast remains a contentious issue. Nevertheless, many benefits are associated with consuming warm lemon water first thing in the morning, such as promoting more transparent skin, aiding digestion, and improving alertness. 

Drinking lemon water in the morning may break a fast, depending on the type of fast you are doing.

If you are doing a complete fast where you abstain from all food and drinks except for water, drinking lemon water in the morning would break your fast, as it contains calories and can stimulate digestive processes.

However, if you are doing a time-restricted feeding protocol, such as 16:8 or 18:6, where you limit your eating to a specific window of time during the day, then drinking lemon water in the morning would likely not break your fast, as long as you consume it outside of your eating window.

Similarly, if you are doing a modified fast, such as a bone broth fast or a juice fast, then drinking lemon water may be allowed, depending on the specific guidelines of the fast.

However, lemon acidity is known to break down food in the stomach partially; therefore, scientific evidence suggests that consuming anything other than plain water will begin digestion and effectively break a fast. 

While this debate continues among professionals, understanding individual body composition can be vital to deciding what works best for each person’s routine.

Can You Drink Lemon Water While Fasting for Blood Work?

When undergoing routine blood work, many wonders if they can drink lemon water while fasting. 

Lemon water, like other beverages, can stimulate digestion and affect glucose and insulin levels in the blood. This can impact the accuracy of blood tests, particularly those that measure glucose, insulin, and certain hormones.

Therefore, consuming only plain water during fasting is best if you are fasting for blood work. This means avoiding drinks containing calories, artificial sweeteners, and other foods or beverages that could affect blood test results.

Generally speaking, most healthcare professionals advise against it. Lemon water is typically considered a liquid intake, meaning it will break a traditional fast for lab work. 

While it may be low in calories and sugar, consuming it could affect the accuracy of your results. If you require hydration when having blood drawn, aim for simple beverages such as water or black coffee – free from cream or sugar. 

Always consult with your medical provider before proceeding with any health-related decisions.
