Can you drink coffee with sugar free syrup while fasting?

Intermittent fasting has become an increasingly popular diet and lifestyle choice in recent years. It involves periods of voluntary abstinence from food and caloric beverages for set lengths of time. Many people find that intermittent fasting is an effective way to lose weight, improve metabolic health, and simplify their dietary regimen.

One very common question that arises for intermittent fasters is whether it is permissible to add calorie-free flavorings, especially sugar-free syrups, to coffee during the fasting window. This article will examine that question in detail.

What is Intermittent Fasting?

Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. It differs from normal eating patterns where meals are consumed throughout the day. The most popular IF protocols include:

  • 16/8 method: Fast for 16 hours per day and restrict feedings to an 8-hour window.
  • 5:2 diet: Eat normally 5 days per week and fast or restrict calories to 500–600 per day for 2 days.
  • Alternate day fasting: Fast or restrict calories every other day.
  • The Warrior Diet: Eat small amounts of raw fruits and vegetables during the day and one huge meal at night.
  • Periodic fasting: Fast for 24-hour periods 1–2 times per week or month.

The main claimed benefits of intermittent fasting include:

  • Weight loss: By limiting overall calorie intake, IF makes it easier to create a calorie deficit.
  • Lower insulin levels: Fasting decreases insulin resistance and lowers insulin levels.
  • Improved cholesterol: IF may reduce LDL and total cholesterol levels.
  • Reduced inflammation: Some studies note declines in markers of inflammation like C-reactive protein.
  • Better blood sugar control: Fasting blood sugar goes down and insulin sensitivity improves.
  • Heart health: Fasting improves numerous cardiovascular risk factors.
  • Cognitive function: IF may boost brain function and prevent neurodegenerative disorders.
  • Longevity: IF triggers repair processes in the body that can extend lifespan.

Given these purported benefits, it’s understandable that many people are eager to try intermittent fasting. But they also want to know whether they will still be able to enjoy their coffee with flavor add-ins during the fasting period.

What Can You Consume During Fasting?

To get the full benefits of intermittent fasting, it’s important to avoid any foods or beverages containing calories during the fast. Consuming calories breaks the fasted state. The general guideline is that under 50 calories will not break your fast, but the closer you can stick to zero, the better.

Some fasting protocols like alternate day fasting do allow for a small intake of calories on fasting days, usually around 500. But that would not apply to daily 16/8 or similar fasting schedules.

On full fasting days, plain or carbonated water, unsweetened tea or coffee, and other no-calorie or very low-calorie beverages are universally permitted. You can also consume sugar-free gum and mints, although some artificial sweeteners may still elicit an insulin response.

The intake of supplements like vitamins, minerals, amino acids (like branched-chain amino acids), apple cider vinegar, bone broth, and fiber supplements will not break your fast either.

What About Sugar-Free Syrups and Creamers?

This brings us to the main question – are sugar-free coffee syrups off-limits when fasting? Unfortunately, there is no straight yes or no answer. There are a few factors to consider:

1. Ingredients

Read the ingredients list carefully. Many sugar-free syrups and creamers contain:
– Artificial sweeteners like sucralose, aspartame, acesulfame K or saccharin. These have minimal calories and do not affect blood sugar.
– Natural sweeteners like stevia, monk fruit or erythritol. They also have negligible calories.
– Thickeners and emulsifiers like xanthan gum, cellulose gum or carrageenan. They add volume without calories.
– Natural and artificial flavors. These don’t spike insulin.
– Milk or cream derivatives like casein or whey. They do contain calories and affect insulin.

As long as the main sweetener is non-caloric and the other additives are free of sugar and fat, the syrup should not break your fast from a caloric perspective.

2. Insulin Response

Even natural no-calorie sweeteners can provoke an insulin release. This compromises some of the benefits of fasting like lowering insulin and increasing insulin sensitivity.

However, research shows the insulin response to non-nutritive sweeteners is negligible compared to real sugar. One study found stevia, aspartame, and acesulfame K had less than 1% of the insulin impact of table sugar.1 Another study found similar results for sucralose.2

So while non-nutritive sweeteners are not completely metabolically inert, their effect on insulin secretion is minimal. Using modest amounts of no-calorie sweeteners during fasting hours is unlikely to be detrimental.

3. Gut Health

Artificial sweeteners may adversely alter the gut microbiome, which plays a role in metabolic health. Some research indicates that frequent consumers of artificial sweeteners have poorer blood sugar control.3

However, gut microbiome changes appear to be small and highly individualized. For most people, occasional use of artificial sweeteners during fasting is not a major concern. But you can avoid this issue altogether by choosing only natural sweeteners.

4.Flavor Without Calories

The bottom line is that adding modest amounts of sugar-free syrup to your coffee is unlikely to negate the benefits of intermittent fasting for most people. The combination of flavor without calories or significant insulin impact provides the best of both worlds.

However, everyone is different. You may wish to experiment with both options to see if you notice any differences in hunger, energy or weight loss results.

Choosing the Best Sugar-Free Syrups for Fasting

If you do opt to use sugar-free syrups during your fasting window, look for products that meet the following criteria:

  • Low calorie or no calorie – Avoid any with more than 10 calories per serving
  • No sugar – Should have 0g of sugar per serving
  • No fat – Should have 0g of fat per serving
  • Non-nutritive sweeteners – Aspartame, sucralose, stevia, erythritol, monk fruit are okay
  • No milk-derived ingredients – Avoid casein, whey or cream
  • Natural flavors – Better for gut health than artificial flavors
  • Clean ingredients – Short, recognizable ingredient lists are best

Some of the top brands that meet these criteria include:

Jordan’s Skinny Syrups

Jordan’s offers a wide array of sugar-free syrup flavors sweetened with sucralose and stevia. Most flavors are 0 calories and they have simple, high-quality ingredients.

Skinny Mixes

Skinny Mixes also use sucralose and stevia to create flavored syrups with 0 calories and 0g sugar. Great range of flavors from caramel to pumpkin spice.

Torani Sugar Free Syrups

Torani makes sugar free versions of many of their popular syrups. Sweetened with sucralose, most flavors are 0 calories and 0g sugar. High quality natural and artificial flavors.

Davinci Sugar Free Syrups

These syrups use a blend of sucralose and acesulfame K to provide sweetness without sugar or calories. All are 0 calories and 0g sugar.

Monin Sugar Free Syrups

Monin offers a nice selection of sugar free syrups in flavors like caramel, pumpkin spice, and English toffee. Sweetened with sucralose and under 5 calories per serving.

Russell Stover Sugar Free Syrups

Russell Stover is known for their sugar free candies, so their line of sugar free syrups is not surprising. Made with sucralose, most flavors are 0 calories and 0g sugar.

Make Your Own Healthy Syrups

For the most natural option, you can make your own healthy syrups at home. Stevia, erythritol, and monk fruit make good no-calorie sweeteners. Extracts like vanilla or almond provide sugar-free flavor. Simmer ingredients with a little water to produce a simple syrup.

How Much Sugar-Free Syrup Can You Use When Fasting?

When using sugar-free syrups or creamers during fasting windows, moderation is key. A brief period of heightened insulin is probably not a big concern, but chronic, excessive intake may be counterproductive.

Here are some suggested guidelines for syrup intake while fasting:

  • Limit to 1-2 servings per day
  • Keep servings small – 1-2 Tbsp syrup per beverage
  • Try to use only on occasional fasting days, not daily
  • Avoid syrups that are high calorie or made with sugar alcohols
  • If weight loss stalls, try abstaining from sweeteners for a period

The best approach is to listen to your body. Avoid excessive consumption of even non-nutritive sweeteners. And be prepared to cut them out if you noticedecreased fasting benefits.

Tips for Adding Sugar-Free Syrups to Coffee

If you do decide to add sugar-free syrups to your intermittent fasting coffee regimen, here are some tips for using them:

  • Start with just 1 tsp of syrup and adjust to taste preference
  • Mix syrup thoroughly to evenly distribute flavor
  • Add syrup to hot coffee rather than pouring syrup in cup before brewing
  • Use syrups to enhance coffee flavors like vanilla, caramel, and hazelnut
  • Try making flavored whipped cream with sugar-free syrups for topping
  • Mix different syrups like caramel and coconut for unique flavors
  • Sweeten other allowable beverages like tea, carbonated water, almond milk
  • Look for interesting seasonal flavors like pumpkin spice or gingerbread

Following fasting best practices while allowing yourself these sensible indulgences is a sustainable strategy.

Can You Add Sugar-Free Powdered Creamer While Fasting?

In addition to liquid coffee syrups, many people enjoy using powdered coffee creamers to add flavor and creamy texture to their brew.

Popular brands of powdered creamer like Coffee Mate and Nestle offer sugar free versions sweetened with sucralose or stevia. At first glance, these creamers would seem like an ideal fasting option.

However, upon closer inspection of the ingredients list, powdered creamers may be less suitable for intermittent fasting than liquid syrups due to a few factors:

  • Higher calorie – Powdered creamers may be 10-20 calories vs. 0-5 for syrups
  • Milk proteins – Contain casein, whey concentrate, or sodium caseinate
  • Higher fat – Powdered creamers have 1-2g fat per serving
  • More carbs – Up to 5g net carbs due to added sugars
  • More fillers – Starches, dipotassium phosphate, gums

The protein, fat, carbs and insulin impact of powdered creamer may technically break your fast. They are less ideal than sugar-free syrups or just black coffee.

That said, some people may include them during fasting windows in small amounts without issue. As always, pay attention to your body’s feedback and adjust your approach accordingly.

Conclusion

Based on the available evidence, adding small amounts of sugar-free syrup or liquid creamer to coffee during intermittent fasting hours is unlikely to cause significant metabolic issues or break your fast. While plain black coffee is ideal, these additions provide flavor and variety that make fasting regimens sustainable.

Focus on choosing high quality products free of sugar, fat and calories. Be mindful of portion size, limiting intake to 1-2 servings per day. Avoid excessive consumption of even natural sweeteners. And of course, listen to your body’s signals and adjust your habits when needed.

With the right approach, you can fast clean while still enjoying flavored coffees that help you stick with an effective intermittent fasting protocol.
