What is Intermittent Fasting?

What Is Intermittent Fasting

It’s a popular diet trend gaining momentum in recent years, and it’s now embraced by millions worldwide. Intermittent fasting is a pattern of eating that involves cycling between periods of eating and fasting.

Intermittent fasting is not a diet in the traditional sense. You don’t have to follow a particular menu or count calories. Instead, you focus on when you eat (the timing) rather than what you eat. During the fasting periods, you don’t eat any food, but you can drink water, tea, coffee, and other non-caloric beverages.

Intermittent fasting is a popular lifestyle trend that has been gaining momentum in recent years. With the rise of this trend, several apps have been developed to help users track and manage their fasting periods. And Lasta is one of these apps.

The Different Types of Intermittent Fasting

There are a few different types of intermittent fasting. The most popular ones include the 16/8 method, the 5:2 diet, and alternate-day fasting.

  • The 16/8 method involves fasting for 16 hours and eating all of your meals within an 8-hour window. For example, you may eat all your meals between noon and 8 pm. This type of intermittent fasting is perhaps the most popular.
  • The 5:2 diet involves eating normally for five days of the week and fasting for two days. You reduce your calorie intake to 25% of your normal daily calories during the two fasting days.
  • Alternate-day fasting involves fasting every other day. On fasting days, you eat either nothing or very few calories. On non-fasting days, you usually eat.

Intermittent fasting has many potential health benefits, such as weight loss, improved mental clarity, and reduced inflammation. Additionally, intermittent fasting may help reduce your risk of chronic diseases like obesity, cardiovascular disease, and type 2 diabetes.

Before starting any diet, you must talk to your doctor. Everyone is different, and intermittent fasting may not be suitable for everyone. Your doctor can help you determine if intermittent fasting is right for you.

Tips for Getting the Most Out of Your Intermittent Fast While Still Enjoying Coffee

Here are some tips for getting the most out of your intermittent fast while enjoying coffee.

1. Type of coffee you’re drinking

First of all, it is important to remember that anything with more than 50 calories will break your fast. Therefore, it is best to stick to coffee with a splash of milk or cream, as these will contain less than 50 calories.

If you’re relying on sugary coffee drinks like lattes or frappuccinos, you’ll be breaking your fast with added sugar and calories that could slow down your progress. Stick to coffee with low-calorie sweeteners like stevia, monk fruit, and xylitol, or opt for black coffee for the most fasting benefits.

Avoid any specialty coffee drinks, as they will almost certainly contain more than 50 calories.

2. Stick to black coffee.

It’s important to remember that any calories that you consume while fasting still count towards your fasting window. This means that if you’re drinking coffee with cream and sugar, you’re breaking your fast and reducing its effectiveness. Stick to black coffee to get the most out of your intermittent fast.

3. Choose quality coffee.

When you’re fasting, drinking high-quality coffee can make a huge difference in how you feel. Quality coffee beans can provide a boost of energy and help to reduce hunger cravings. Choose a high-quality coffee from a trusted source to get the most out of your fast.

4. Choose the right time and coffee strength.

The timing of when you drink your coffee is also essential. If you’re fasting from 8 PM to 12 PM, avoiding drinking coffee in the morning is best. Coffee can stimulate your appetite and interfere with the fasting process. If you’re planning to drink coffee while fasting, it’s best to consume it early in your fasting window.

It’s also important to choose the right strength of coffee. If you’re an avid coffee drinker, you may be tempted to drink a more robust cup of coffee while fasting, which can negatively impact your fast. Stick to a milder coffee to ensure you don’t exceed your caffeine limit.

5. Hydrate throughout the day.

Coffee is a diuretic, meaning it causes you to lose more water than you take in. To counter this, be sure to stay hydrated throughout the day. This means drinking plenty of water and avoiding other diuretic drinks, such as soda or alcohol.

6. Don’t drink coffee on an empty stomach.

Drinking coffee on an empty stomach can irritate your stomach and cause nausea, headaches, and other unpleasant side effects. To get the most out of your fast, wait until after you’ve eaten something to enjoy your coffee.

How Much Is Caffeine Too Much?

How Much Caffeine Is Too Much When You Are Intermittently Fasting?

So, if you’re considering intermittent fasting and want to enjoy a cup of coffee or tea, it’s essential to pay attention to how it affects you.

Generally, up to 400 mg of caffeine daily is considered safe for most people. However, excessive caffeine intake can adversely affect your sleep quality, which can ultimately affect your metabolic health in the long run. Therefore, limiting your caffeine intake to moderate when you are intermittently fasting is best.

FAQs About Can You Drink Coffee While Intermittent Fasting

The Role of Hydration When You’re Doing an Intermittent Fast

When you are doing an intermittent fast, hydration is essential. It would be best if you drank water or other noncaloric beverages first thing in the morning when you wake up to ensure your body has what it needs after a night of rest. You should also drink water and other noncaloric beverages throughout the day to ensure you are properly hydrated.

The Impact of Sugar on Your Body During an Intermittent Fast

Eating foods high in added sugar can increase insulin levels, which can cause more fat to be stored in your body. Additionally, the sugar in processed foods and drinks is devoid of nutrition and amounts to sweet, empty calories.

Intermittent fasting can help to reduce insulin levels and thus increase lipolysis by lowering your cravings for sugar. It is important to note that the main risks of IF for people with diabetes include low blood sugar and dehydration, so it is essential to consult a doctor before attempting an intermittent fast.

Is It Better To Drink Black Coffee Or With Milk And Sugar?

It is generally considered better to drink black coffee during intermittent fasting for the best results. Adding ingredients such as milk, cream, plant-based milk, sugar, or creamers can affect your metabolism and blood sugar, potentially disrupting the metabolic benefits of intermittent fasting. Therefore, it is better to avoid adding these ingredients and stick to black coffee for the most effective intermittent fasting results.

What Are The Best Choices For Adding Flavorings To My Coffee?

The best choices when adding flavorings to your coffee while on an intermittent fast are non-dairy creamers and artificial sweeteners. Non-dairy creamers provide a rich and creamy taste to your coffee without the calories and fat of dairy products.

Artificial sweeteners are a great way to sweeten your coffee without adding extra calories. The key is to choose a non-dairy creamer or artificial sweetener that is sugar-free and contains healthy fats, such as coconut oil, to help promote satiety.

What Type Of Sweetener Is Allowed When Drinking Coffee During An Intermittent Fast?

Artificial sweeteners such as Stevia, Swerve, Aspartame, and Splenda are allowed. These sweeteners will not break your fast, as they do not affect insulin secretion or blood glucose. However, it is important to note that consuming any sweetener will break your fast and trigger insulin secretion. Therefore, it is best to opt for unsweetened coffee if possible.


Overall, the answer to the question of can you drink coffee while intermittent fasting is yes. Just make sure to stick to black coffee and not overdo it. Doing so will help you reap the most benefits from this popular dietary approach.
