Fasting And Artificial Sweeteners
Sweet taste is a much-discussed topic regarding intermittent fasting and the keto diet. On the one hand, it is difficult to get away from it. On the other hand, it substantially promotes cravings.
Most sugar-free sweeteners have zero protein, carbohydrates, and calories. Therefore, they do not raise the blood sugar level. But is the calculation that simple?
No, since people often forget that both intermittent fasting and keto have one essential goal: Lowering insulin levels to allow your body to tap into stored fat for energy.
Since the storage hormone, insulin, prevents body fat breakdown and ketone production, a significant increase in insulin levels breaks the fast.
Unfortunately, most diet gurus have not done their homework in this context.
As endocrinologist and fasting pioneer Dr. Jason Fung correctly points out, it does not matter whether food increases blood sugar levels as long as it increases insulin levels .
Beckys Glucose Results: Equal
Her blood glucose was at 94 mg/dL, it went up to 105 mg/dL at 30 minutes, then back to 94 mg/dL at 60 minutes, and up to 103 mg/dL at 120 minutes.
It kind of went back and forth a couple of times over the test in both your ketones and glucose.
Becky:
When we look at my results for Equal, they are actually very similar to my results for sugar.
Keith:
Yes. Your blood glucose definitely went up a little bit, and your ketones came down a little bit.
Becky:
Nothing significant happened, I didnt really benefit from it.

Drinks To Avoid While Fasting
Because of the massive amount of sugar that Americans eat on average, many people have become dependent on glucose for energy. When you eat a lot of sugar and that sugar isn’t utilized for energy, your body breaks it down and eventually stores it as body fat, per UC Berkeley. In addition, the refined sugar found in most beverages digests quickly, spiking both your blood sugar and your insulin levels.
Sugar is also addictive. Indeed, a July 2013 review in Current Opinion in Clinical Nutrition and Metabolic Care found that sugar and sweetened beverages and foods induce reward and craving responses in the brain that are comparable to the responses triggered by addictive drugs, which continue the cycle.
As a result, it’s best to avoid sugary drinks that can break a fast, including:
- Soda
- Kombucha
Can You Drink Diet Soda, Gatorade Zero or Propel While Fasting?
Drinks like diet soda, Gatorade Zero and Propel don’t have sugar or calories, so they may seem OK for fasting.
But its not that simple. These drinks and similar flavored water products like Mio contain artificial sweeteners, which can increase sugar cravings and make fasting more challenging, per Harvard Health Publishing. Accordingly, it’s best to skip these beverages while you’re fasting.

Is Black Coffee Okay For Intermittent Fasting
Is black coffee okay to consume for people who are undergoing intermittent fasting?
The answer is yes, it is okay for people to drink black coffee even during fasting periods. This is because it contains relatively low calories which cannot hinder your fasting.
However, black coffee should be taken in moderate amounts only as overconsumption can damage your health.
Sue Ryskamp, a Senior dietitian who works at the Michigan Medicines Frankel Cardiovascular Center, said that it is okay to drink a coffee with the condition thatit has to be pure black coffee with no sugar or creamer in it.
A cup of black coffee contains approximately about threecalories along with very few amounts of minerals, fats, and protein.
Although not scientifically proven, it was claimed by some people that drinking black coffee helps suppress appetite making it much easier to fast.
In general, though, drinking black coffee is unlikely hinder your intermittent fasting.
Testing The Effects Of Cream In Coffee When Fasting
On my second YouTube channel that I run with my husband, Keith, we perform a lot of small-scale tests to determine how different foods affect our intermittent fast.
On testing days, we get up in the morning, take our baseline blood glucose and ketone readings, consume something, and then retest our blood at 30, 60, and 120 minutes.
What wed like to see is that a food or drink does not cause a spike in glucose or a drop in ketones, because that may indicate a rise in insulin. Insulin is the fat-storing hormone, so if it goes up, fat is being stored, not released and burned.
When we tested heavy cream, the result was favorable meaning it caused a slight drop in glucose and a slight rise in ketones.
From that, we concluded that cream in your coffee would not knock your body out of fat-burning mode, and therefore it was okay to consume during your intermittent fast!
Now admittedly, these home experiments with just two subjects are far from a rigorous scientific study. There are several factors to consider when determining if youd like to add cream to your coffee.

Can I Drink Herbal Tea While Intermittent Fasting
Although herbal and fruit tea is prevalent here in Central Europe, they are often big surprises. You usually cannot be sure what is inside.
Besides regular dried fruits, candied fruits often hide in fruit tea. Moreover, they often hide in herbal tea as well. And their sugar content will break a fast.
Accordingly, the variance in fruit tea is large . Like green tea, it can contain almost none, just too many for intermittent fasting, or a vast amount of hidden carbohydrates.
Therefore, as with food purchases, the basic rule is: read the label carefully and avoid any suspicious contents. The same applies to herbal tea, which tends to perform better because it does not commonly contain dried fruits.
If you want to be on the safe side, do not drink herbal or fruit tea during intermittent fasting.
What Is Intermittent Fasting
Intermittent Fasting is one of the most popular weight loss trends to date. Unlike a typical diet, intermittent fasting is about when you eat, instead of what you eat. This trend requires a set eating schedule and consistent fasting times to be truly effective.
An eating pattern rather than a conventional diet, the belief is that periods of fasting are more normal than eating 3 square meals per day because ancient hunter-gatherers would go through regular periods of scarcity due to an inability to find food.
There are a variety of fasting schedules and plans that have been designed to accelerate weight loss through metabolic switching.
Essentially, when your body is fasting, it uses stored body fat for energy. Levels of Human Growth Hormone increase up to 5 times their regular amount, which induces fat loss and muscle gain, and insulin levels drop to make stored fat more immediately accessible.
Hormone changes may also cause your metabolic rate to increase, leading to more calories burned.
Your cells also begin repair processes like autophagy, in which your cells digest old, unusable cellular protein build-up.
Prior to beginning an intermittent fasting schedule, approval should be given by your primary care provider. They can answer any questions you may have regarding intermittent fasting and how it will affect your personal physical health and mental wellness.

Health Benefits Of Coffee
However, being a regular coffee drinker may decrease the risk of developing diabetes according to this study. The study tracked over 100,000 men and women across three different studies and found that people in the research studies the increased their daily coffee consumption by one cup a day actually decreased their risk of developing diabetes by about 11%. What was also surprising is that those people that their coffee consumption by one cup a day actually increased their risk of developing diabetes by about 17%.
So even if there is a slight acute increase in blood glucose or insulin levels from the caffeine in coffee, we dont see long-term negative impact on our health.

Ketosis And Weight Loss
Since fasting is the most effective way to lower insulin levels, it is essential for weight loss. Accordingly, insulin is the crucial storage hormone in the human body.
Therefore, it is responsible for signaling cells to take up glucose from the bloodstream and store excess energy as fat or glycogen.
Furthermore, insulin blocks the enzyme that can break down body fat .
Accordingly, scientists can predict about 75% of possible weight gain and loss in overweight people by analyzing their insulin levels .
The 16-hours of fasting cut off the supply of nutrients, lower insulin levels, and thus end the bodys storage mode.
The body can then begin to break down the carbohydrate stores . Once the glycogen stores are empty, your body can start to burn stored fat for energy.
This fat burning process is called ketosis and, contrary to many myths, is an entirely natural mechanism that has ensured our species survival.
Nature has designed the body to build up fat reserves during abundance and tap into this body fat for energy when food is scarce.
Nowadays, instead of food shortages, we experience an endless summer and eat round the clock. Thus, we gain weight.
Therefore, intermittent fasting can help to restore the natural balance between feasting and fasting.
What You Can Drink During Intermittent Fasting
If you want to skip the details above: Here is the bottom line!

However, green tea has activated autophagy in human cells, but these were previously implanted into mice .

Coffee Sweetener Dos And Donts
If you must have a little sweetness in your coffee, choose wisely. Sweeteners will break your fast by triggering insulin secretion. Artificial sweeteners such as Stevia, Swerve, Aspartame, and Splenda wont break your fast, since they dont seem to have an effect on insulin secretion or blood glucose. But, you may wish to avoid them for other health reasons.
Cinnamon wont break your fast, and it may increase insulin sensitivity. You can also add a little unsweetened cocoa powder or ginger to your brew.
Watch out for hidden sweeteners if you get your coffee from a coffee shop. Soy, rice, and nut milk alternatives are typically sweetened.
Other Diets This Recipe Is Good For

Can I Drink Carbonated Water During Intermittent Fasting
When it comes to what you can drink during intermittent fasting, in my opinion, carbonated water is an outstanding choice.
On the one hand, it offers effects that excellently support intermittent fasting:
- It curbs the appetite,
- Helps with an upset stomach,
- Or even with cramping.
On the other hand, superior carbonated water can bring more than 100 mg per liter of the essential electrolytes magnesium, sodium, and calcium into the body.
Therefore, carbonated mineral water is the best choice. But only if you have access to natural, highly mineralized brands.
Here in Austria, we are blessed with incredible natural springs. But depending on where you are located, you might have to check labels carefully.
Hence, access to high-quality mineral water can provide electrolytes, even during extended fasts. In this case, you dont need to fall back to bone broth to get them.
