Intermittent fasting apps are booming globally.  “Mens sana in corpore sano,” a Latin phrase that translates into “A healthy mind in a healthy body,” fits perfectly in today’s scenario. The world has started learning the importance of having good fitness. The existence of intermittent Fasting apps (IF) is the perfect example of it.

Recently, people are not only prioritizing their diet but also how they consume it. The awareness of how and when you need to eat is what IF apps are all about. It would be wrong to assume them as a stopwatch with periodic reminders. 

The Intermittent Fasting journey is not a sheer weight loss program, as mainstream media portrays. It displays long-term health benefits at the cellular level. In addition, the concept was first perceived globally in 2012. It was a BBC broadcast journalist Dr. Michael Mosley’s TV documentary Eat Fast, Live Longer, and the book The Fast Diet. 

Since then, many books and Intermittent Fasting Apps have seen launches. You can also easily find an intermittent fasting mobile app development company with eye-catching services. More so, people also struggle with typical questions-

• Should I try Intermittent Fasting?
• Is it a fad?
• How will it help me?
• Which app should I download?

True, Beginning is always the hardest. Also, challenging in some cases. Thus, proper and systematic knowledge will leave no doubt in mind. 

Hence, let’s understand what this fuss is all about-

What is an Intermittent Fasting App?

Intermittent fasting focuses on following a periodic eating schedule with no snacks in between. You can find various diet plans which will help your metabolism and improve cellular and molecular mechanisms. As a result, it prevents many diseases and improves overall mental, physical, and emotional health. 

So, when other diet plans focus on what to eat, it tells you when to eat. The general intermittent fasting schedule abides by extended 16 hours of fasting periods at night. Then, they follow an 8-hour window of conscious eating during the daytime.

Most people prefer to keep fast at night and eat during the daytime. Further, Intermittent fasting is different from Circadian Rhythm, which follows the concept of “Daylight eating and nighttime resting.”

What are the Types of Intermittent Fasting Apps?

First of all, you need to understand the different types of fasting. It is essential to know which works better for you. You can schedule your intermittent fasting plan as you like. However, there are four most popular intermittent fasting windows to consider. They are-

• 16:8 Plan or Time Restricted Eating-

Time-specific eating, commonly known as the 16:8 method, is the most popular. People observe a fasting period of 16 hours. It usually starts after sunset and continues till mid-day. Then, they follow a healthy diet routine for the next 8 hours.  

Some people also use a 14:10 intermittent fasting schedule. In this, fasters have a 14-hour fasting period and a 10-hour eating window. Such types of fasting periods are considerably easy for first-timers. Because people don’t need to change their meal plans significantly.

Thus, it is the easiest and most convenient way of fasting. The benefits of the 16:8 plan include weight loss, balanced blood sugar levels, and elevated longevity.   

• 5:2 Plan-

It is considered one of the most flexible fasting schedules. In this, people usually eat five days a week. Then, they take a break for any two days with a break in between. 

For example, people keep fast on Monday and Thursday and eat around 400-600 calorie meals. The meal they consume is high in Protein and fiber, also not to go over calorie count. For the rest of the days, they go on their usual diet. 

However, you must have a healthy diet on non-fasting days, if you want to see the results. The benefits of the 5:2 plan include improved blood lipids, reduced insulin resistance, decreased inflammation, and weight loss.  

• Alternate Day Fasting-

Alternate-day fasting is the best IF approach to preventing heart disease and type-2 diabetes. It is also called “modified fasting.” Here, You consume one low-calorie meal, usually up to 500 calories the fasting day.

Then, you consume a nutritious meal the next day. Further, you repeat the process for the rest of the week. In other words, it is called “The Every other Day Diet” by Dr. Krista Varady. You consume only 20-25% of your energy requirement on the fasting day. 

However, you may also have calorie-free diets or liquids, such as water, tea, and coffee. This fasting method helps preserve lean muscle mass during weight loss. 

• 24-hour Fasting-

Another form of Intermittent Fasting plan is also called the “Eat-Stop-Eat” approach. It is different from alternate-day fasting. Here, you consume only calorie-free beverages on the fasting day.

Then, you take a healthy meal the next day. So, the schedule proceeds for weeks until you get the desired result. Besides weight loss, it is most beneficial in improving metabolism and cardiovascular health. Other benefits include-

• Balancing cholesterol and sugar levels.
• Lowering risks of coronary artery disease. 
• Reducing inflammation.
• Lowering risks of certain cancers.
• Lessening the chances of getting Alzheimer’s and Parkinson’s disease.

Since it follows a strict calorie-free diet on a fasting day, certain complications may occur. There may be fatigue and headaches. You may also feel quite “hangry” on the fasting day. 

How does an Intermittent Fasting App Work?

You need to choose the best IF schedule that suits your lifestyle. Then, only you will be able to see the desired results. Even after downloading the best intermittent fasting app, you still need the discipline to witness results. 

Though, the IF schedule looks challenging. Yet, it doesn’t need to be hard to follow. You can use the circadian rhythm to abide by a hassle-free IF plan. 

As Dr. Michael Mosley stated in his book “The Fast Diet”-

“The idea here is that you simply extend your normal overnight fast. If you stop eating at 20:00 and don’t start eating again until 10:00, that is a 14-hour fast. That way you get some of the benefits of intermittent fasting without worrying about calorie counting.”

First, you need to set the IF schedule in the app. Then the built-in fasting tracker will keep you updated about all the precautions and timing. It will track your weight loss journey and provide an analytical report. 

Thus, you don’t need to worry about scheduling your journey. Also, no need to keep track of fasting hours. The intermittent fasting tracker will do that for you. Some IF apps offer advanced features, such as meal planning, progress report, pictures, suggestions, etc. 

How Intermittent Fasting is Beneficial for Your Health?

Or, Does Intermittent Fasting actually help people?

For years, people have been bearing the fruits of irregular diet, poor eating habits, and lack of proper exercise. Many people have also been taking either large or insufficient meals at odd times. It is not all that they want now.

After witnessing the adverse effects of an improper lifestyle, people started looking for alternatives. It gave a push to many researchers worldwide. The latest research shows that it helps burn fat and lose weight only by making a conscious diet routine. 

On fasting day, the insulin level goes down for the initial hours. Thus, it encourages fat cells to release sugar and convert it into energy. Next few hours, the body loses more fat cells due to a lack of food intake. Hence, it leads to weight loss. 

IF also helps with aging and cognition, manages autophagy & Gut microbiomes, lowers oxidative stress and reduces risks of neurodegenerative diseases. IF also has fast effects on the skin, reduces hypertension, and boosts the immune system. 

Needless to say, an intermittent fasting diet is a sure way to get your health back. Researchers say it takes around 2-4 weeks to get familiar with the IF routine.
