Intermittent Fasting (IF) is the most popular health & fitness trend worldwide. Involving alternating cycles of fasting & eating, IF is a famous eating plan proven to have been fruitful to many. Several studies suggest IF helps in weight loss, enhances metabolic health, protects against disease, and helps live longer. It has been said to be good for people suffering from chronic conditions and autoimmune diseases.

However, intermittent fasting can be quite challenging as this eating plan requires one to be mindful of the time and when one is eating. This is why intermittent fasting apps can be quite helpful, as they make intermittent fasting very manageable. Many IF apps are present in the fitness market; however, not all those apps are the best, and one must be conscious before choosing their app. This article will explore a little about Intermittent Fasting, how it is beneficial, and which are the best IF apps out there.

What is Intermittent Fasting?

Most diets focus on ”what” to eat, but Intermittent fasting is all about ”when” to eat. With intermittent fasting, one eats only during a particular time. IF is a great way to get a lean body without following any crazy diets or cutting on the calories. In fact, when starting intermittent fasting, most of the time, people try to keep their calorie intake the same by eating bigger meals during a shorter time frame. It is also a good way to keep muscle mass on while getting lean. It is said that IF is a great way to keep bad weight off while keeping the good weight on with just a little behavior change.

How Intermittent fasting apps can help?

Fat loss is a great benefit of Intermittent Fasting, but that’s not it; the other benefits consist of:

Intermittent fasting makes the day simpler

IF brings additional simplicity to life. Before starting Intermittent Fasting, most people are in the habit of unconscious eating throughout the day; however, it is changed with Intermittent Fasting as it restricts people to have just two to three meals a day. This way, it saves people from stressing about their meals throughout the day and brings in much-needed discipline.

Intermittent fasting helps live longer

Many studies have verified that restricting calories helps extend your life, as when one starves, the body finds ways to lengthen life. However, people mostly like to enjoy life, and the thought of starving restricts them from doing so; hence Intermittent Fasting can be the answer to them. IF activates many of the same mechanisms to extend life as calorie restriction. So the people receive the benefits of a longer life without starving.

Intermittent fasting may reduce cancer risk

Even though this needs to be researched deeper, early reports do suggest a positive relationship between cancer and fasting. The study of 10 cancer patients suggests the side effects of chemotherapy may dimmish by fasting prior to the treatment. Another study supports this finding as it used alternate day fasting with the cancer patients, and it turned out that fasting prior to chemotherapy resulted in better cure rates and fewer deaths. This comprehensive analysis of several studies on fasting and disease concludes that fasting appears to reduce the risk of cancer and even cardiovascular disease.

Intermittent fasting is way easier than dieting

Most of the diets fail not because people switch to the wrong foods but because the diet is not followed for the long term. Hence, it is a behavior change issue. However, Intermittent Fasting is remarkably easy to implement once people get over the idea that they require to eat throughout the day. This study found that IF was an effective weight loss strategy for obese adults, and it concluded that the ”subjects in question” quickly adapted to IF routine.
