Role of Calories in Intermittent Fasting

Calories are the main energy source for your body to be able to do everyday activities. Calories come from macronutrients in the food you eat and they include carbohydrates, proteins, and fats. 

Intermittent fasting is a practice in which you cycle between periods of eating and fasting, where during fasting hours you abstain from calorie consumption. When the body does not ingest calories it enters a state of ketosis. Ketosis is a metabolic state where the body uses fat for energy rather than glucose. Reduced calorie consumption alongside ketosis fosters weight loss and enhances various physiological processes such as autophagy, improved insulin sensitivity, and increased energy levels.

Can You Eat Zero-Calorie Foods During Fasting?

You can eat zero-calorie foods while fasting. Nonetheless, as far as science knows, there are no 0-calorie foods. All foods and drinks (except water) contain calories to some degree. So, yes you can eat zero-calorie foods while fasting, but it is not recommended as it can break a fast. You should only eat them during the eating window. You can, however, drink zero-calorie beverages during the fasting period, we’ll talk more about these later on.

Tips on Zero Calorie Options During Intermittent Fasting

Avoid Additives

While some artificial sweeteners and additives may have no calories, it is not entirely clear whether or not they impact fasting. Although they have low to no calories, they might stimulate insulin responses or digestive processes. It is better to be safe than sorry, so avoid them to ensure you get the full benefits of fasting and don’t jeopardize your progress. 

Some additives that typically do not impact fasting include:

Most studies found that low or no-calorie sweetened foods or beverages did not increase hunger or subsequent food intake. However, it's important to note that artificial sweeteners and additives, despite having virtually no calories, may affect individuals differently.

Tackling Hunger Pangs

Hunger is imminent when fasting, particularly during the first days, making you reconsider whether thinking about intermittent fasting was even a good idea. Taking advantage of 0-calorie drinks for fasting allows you to manage hunger without disrupting your fast.

Another way you can tackle hunger is to incorporate fiber-rich foods during eating windows, doing so will give you a sense of fullness for longer periods. Practice meditation, and engage in physical activity and mindful eating to help control hunger during fasting.

Stay Hydrated

Maintaining optimal hydration while fasting is key to a healthy fasting experience. Since you are not obtaining the same amount of water from foods, you must compensate for it by drinking more water than usual. Drinking electrolyte beverages is also allowed, but you must verify they are sugar-free. 

Look Out for Hidden Calories and Overconsumption

Be cautious of foods and drinks marketed as zero-calorie as they may contain hidden sugars. During eating windows, eat balanced, nutrient-dense meals and ensure you stay within your calorie limit to avoid overconsumption. Use the Fastic app to guarantee you stay within your daily calorie limit. Its calorie counting system makes it possible to easily manage and spread out your caloric limit however you prefer. 

Zero-calorie foods and beverages are paramount for an enjoyable and successful fast because they provide a sense of satiety without breaking your calorie restriction and aid in managing hunger pangs. Incorporate these options into your fasting routine, preferably during the eating window, for better fasting results.
