Best Intermittent Fasting Apps – Intermittent fasting, or IF, is a current diet trend that works around a simple concept: you can eat almost anything you like, but only during a certain time. However, unlike other diet plans, this regimen is unique because it has scientific evidence to support its claims. Also, our Android and iOS app development teams stand by the fact that intermittent fasting apps are much more popular than any other fitness application. Stefani Sassos, a qualified nutritionist and deputy nutrition director of the Good Housekeeping Institute, explains that “when it comes to shedding excess pounds, the research on conventional intermittent fasting is highly effective.” In this blog, we will discuss here best free intermittent fasting apps for weight loss in 2024.

Although fasting can hypothetically reprogram your metabolism, it may lead to weight loss because you consume fewer calories when you limit your eating to specific time frames.

Types of Intermittent Fasting 

One of the biggest reasons intermittent fasting appeals to many people is that it usually does not necessitate counting calories or monitoring macronutrients; rather, it simply entails setting a time window for eating that suits you. There are a variety of IF schedules to choose from, including the standard 16:8 cycle, the 5:2 cycle, or the highly rigorous One Meal a Day (OMAD) plan. There are different types of free intermittent fasting apps that you can take help from an intermittent fasting diet that you can follow.

1. The 16:8 Method

As the name suggests, this fasting plan allows you to eat anything during 8 hours of the day and wants you to abstain during the remaining 16 hours. Therefore, this plan goes with the time-restricted feeding (TRF) method.

The best part is that this regime allows you to choose 8 hours of the day as your eating hours. Some people skip breakfast to fall under this regime, while others skip dinner. Due to this flexibility, this is among the most popular intermittent fasting plans.

2. The 5:2 Method

Unlike the 16:8 method which deals with hours of the day, the 5:2 method deals with days of the week. In this method, you eat a normal meal for 5 days a week and then for the rest 2 days, you cut your calorie intake to a quarter of your regular meal.

Studies prove that the 5:2 method is as effective as any other intermittent fasting plan, along with being highly flexible that allowing you to choose any 2 fasting days.

3. One-Meal-a-Day (OMAD) Method

As the name suggests, this diet plan allows you to enjoy only one regular meal daily and skip all other meals. Many people have been following this trend even before this came into trend. Traditional fasting methods also follow the same rule: people keep fast for the whole day and have a healthy lunch or dinner.
