All of us practise intermittent (IF) fasting every night while we sleep. However, we dont name it intermittent fasting. Our sleeping hours constitute our daily fasting phase which is well-aligned with our bodys circadian rhythm. A 2012 documentary by BBC, known as Eat, Fast and Live Longer, is often attributed the credit of popularizing intermittent fasting. This dietary pattern has long been associated with reducing the risk of many serious health conditions like breast cancer, heart disease, diabetes, and cognitive decline. In fact, research has proved that restricted calorie intake adds years to your life. Also Read - Following intermittent fasting, but not able to hit your weight loss target? Heres why

There are no recommended foods for intermittent fasting, nor is there any elimination. Here, the theory is calorie restriction for restricted time periods.

What makes this dietary pattern stand apart is the importance it associates with food timing. There are more than one ways of practising intermittent fasting. The basic principle is dividing a day or week into eating and fasting periods. During the fasting periods, you either in low proportions or skip meals altogether. Each method of intermittent fasting comes with its own set of rules and regulations. These are the most popular ones:

Being easy to follow, this is the most popular form of intermittent fasting. The basic principle you fast on one day and feast on the next. On the days of fasting, food intake is minimal, focussed mainly towards liquids while on the feast days, theres no calorie restriction. Research is going on about the health impact of this kind of fasting.

This is quite similar to the previous format with a little difference. In Intermittent fasting with calorie restriction, your food intake on fasting days is limited to only water, herbal teas, and black tea/coffee with no sugar. Also, on feasting days, you have to watch your calorie intake.

In this form, the practitioners eat only during restricted hours of the day. While their food intake is restricted for 6 to 8 hours of the day, the rest no-food window lasts for the rest of the day. They may or may not restrict calories during the eating hours. Research suggests that this eating pattern is optimal for metabolic health.

If you want to follow this type of dietary pattern, then you are allowed to eat for five days a week and fast for 2 days. On the fasting days, you need to limit your calorie intake to 500 to 600 calories and on the feasting days, you are allowed to eat normally with no restriction in mind.

In this method, you fast occasionally during a week or a month and eat during the rest of the days. During the non-fasting days you need to maintain a moderate eating pattern.

This dietary pattern is known for very many health benefits it has. However, scientists suggest that more research is required to validate the preliminary evidences and popular beliefs. Here we guide you on some of the ways intermittent fasting may help you stay healthier.

Many diets impose ban on macronutrients like carbs, fat or protein which are essential for your body. Moreover, those eating patterns require you to substitute many of your favourite foods with the healthier versions. Intermittent fasting doesnt necessitate any of these. However, in this eating style, you have to cut down portions in fasting and non-fasting days too.

Studies have revealed that IF has significant impact on the loss of fat mass. That is why it may be effective in promoting weight loss. However, experts are of the opinion that it is as effective as other diets while it comes to shedding extra kilos. IF may not have additional benefits in this regard. But more research is required to reach a definitive conclusion. A 2018 study published in the journal Nutrition also revealed that IF reduced body mass in the younger population (20 years) while among the older population (50 years), no such evidence was found.

Intermittent fasting is popularly believed to boost longevity. A mice-model study by the National Institute on Aging observes that intermittent fasting extended the longevity of rodents and reduced their risk of life-threatening conditions, especially cancer. However, more research is required to draw a definite conclusion.

Though intermittent fasting isnt a new practice, research on its benefits is still at a nascent stage. Some studies have, however, observed that this dietary pattern comes with its own set of limitations too. For example, you may feel extremely weak, fatigued and cranky on the fast days. Talk to your physician and a nutritionist before embracing this plan. Here is a low-down on some of the side challenges that you may face while following this plan.

This is a common complaint among those who follow intermittent fasting. You may feel severe hunger pangs while on fast as no or very low food intake is allowed.

Intermittent fasting doesnt teach you how to make the right choice of foods because it focusses only on mealtimes and calorie count. So, you dont learn healthy eating skills. However, for long-term health benefits you need to master the art of mindful eating.

Intermittent fasting doesnt talk about or recommend physical activity. So, if you are following this dietary pattern, you are likely to neglect your daily requirement of physical activities.

Practising intermittent fasting may be particularly challenging if you are taking medications that necessitate you to have meals at definite time frames. Speak to your physician if you want to take up this diet while on medications.
