What is intermittent fasting?

Intermittent fasting is a practice of restricting all food intake for certain periods, usually ranging anywhere from 12 and 16 hours. Although there are more extreme versions of intermittent fasting, if you are a beginner who is not supervised by a professional, intermittent fasting regimes with a shorter fasting window may be the most suitable.

One of the main benefits of intermittent fasting is weight loss. Numerous scientific investigations have demonstrated the potential of this dietary approach to support weight reduction, particularly when combined with a nutritious and well-balanced eating diet.

For instance, one meta-analysis concluded that intermittent fasting can help reduce body weight, waist circumference, and body fat mass. However, IF was not superior to calorie restriction, with both interventions potentially sharing overlapping benefits for weight loss.

Moreover, studies suggest that intermittent fasting could be beneficial in aiding blood sugar control and improving insulin sensitivity parameters. For this reason, it is postulated that intermittent fasting could be helpful even without any weight loss — as a tool that supports metabolic health.

While intermittent fasting is generally regarded to be safe, it is crucial to consult your physician before starting any new restrictive diet, especially if you have any underlying conditions. Moreover, intermittent fasting may not be suitable if you have nutrient deficiencies, have a history of or currently dealing with an eating disorder, take part in intense physical exercise, or are in a life stage that requires additional dietary support such as pregnancy or elderly.

Apps for intermittent fasting: do they work?

Intermittent fasting apps are beneficial for tracking one’s fasting and eating windows.

Whether it can work for other purposes will highly depend on many factors. For example, intermittent fasting has been seen to be effective in numerous clinical studies for weight loss. Tracking intermittent fasting without any apps may be difficult, so a specialized app for that may make the process smoother.

Main features of intermittent fasting apps

While the primary function of intermittent fasting apps is fasting time tracking, many other features may be integrated into them. Below we highlighted the most common features found in intermittent fasting apps.

  • Fasting timer. There are several fasting windows to choose from. For example, the 12-hour fasting regime is the most beginner-friendly option, where 12 hours fall under the eating window. The best option ultimately depends on many individual factors. Most fasting apps allow you to customize your fasting window.
  • Calorie counter. Calorie counting may be a useful tool combined with an intermittent fasting timer, especially if your principal aim is to lose weight. Most intermittent fasting apps include some kind of food tracker — but that does not mean that it can compute calories for you.
  • Macronutrient tracker. Some people may also benefit from tracking macronutrients (carbs, fats, and protein). For instance, this could be helpful for certain diets (e.g., keto) or people trying to increase protein intake.
  • Water intake. During your intermittent fasting period, you are encouraged to consume water. You may also include drinks such as unsweetened tea or coffee without milk. By increasing your water intake, you may also curb food cravings you might have while fasting.
  • Meal recommendations. Many intermittent fasting applications include recipes and, sometimes, offer personalized meal plans. While these features can be advantageous, they may not align with individual dietary needs. For precise and personalized dietary guidance, it is strongly advisable to seek consultation with a qualified dietitian.
  • Mood tracker. Certain intermittent fasting applications may incorporate a range of features related to mental well-being, including a mood tracking function. These features may assist users in managing their mental health and noticing recurring emotional patterns.
  • Workout routines. Many intermittent fasting apps are seen as all-in-one tools to improve your general health. For this reason, you may find various exercise routines integrated into them. If you have any specific needs or injuries, always consult a physiotherapist before starting a new workout regime.
  • Compatibility with wearable devices. Some intermittent fasting applications can be used with smartwatches. This can help the user to check their fasting window and receive reminders for when it is time to start or break their fast.
  • Data analysis and reporting. Keeping track of your fasting may be easier if you have in-depth statistics on your progress so far. Some applications may provide personalized reports to offer valuable insights and feedback to users.
  • Stress management tools. These tools could include guided meditations, mindfulness exercises, mood journals, and other features tailored to assist your fasting journey.
