What is Intermittent Fasting?

It is an eating pattern that cycles through periods of eating and fasting. The intermittent fasting plan doesn’t specify the exact foods you need to eat, but when you should eat them. On this plan, a whole food, nutritious diet is recommended. So IF is not a traditional diet, but an eating pattern or habit. In this method, fasting is either 16 hours a day or 24 hours, twice a week.

Fasting is not an unfamiliar practice in human evolution. In fact, it is more common than we know. Our ancient hunter-gatherer humans didn’t have refrigerators, year-round foods, or supermarkets. Sometimes they did not get food to eat. In response to this scenario, they learned to function without food for long periods of time.

In modern society we see that fasting is for spiritual or religious reasons. For example, regular fasting is a common practice in many world religions such as Hinduism, Buddhism, Islam, and Judaism. In fact, when you think about it, intermittent fasting is more natural than having 3 or more meals every single day.

Intermittent fasting methods

There are many ways to do intermittent fasting. The most popular methods are:

,1. Method 16-8

16/8 Intermittent Fasting Method

It is also known as LeanGain Protocol. To comply, you’ll skip breakfast and limit your eating times to 8 hours.

For example, you can eat between 1 pm and 9 pm but then you will fast for the remaining 16 hours.

,2. 5:2 Diet

5:2 Intermittent Fasting Diet

On this method, you typically eat for five days and limit your caloric intake to 500 to 600 calories on two non-consecutive days a week i.e. Tuesdays and Thursdays.

,3. Eat Stop Eat

On this plan you will fast for 24 hours, either once or twice a week. Then eat regularly during fasting days.

On intermittent fasting, you are reducing your caloric intake which leads to weight loss. However, this will only work if you are not consuming much of the junk food or compensating by overeating during the allowed eating period.

Most people prefer the 16-8 method because it’s more durable, simpler, and easier to follow. It’s no wonder it’s also the most popular!

Is intermittent fasting good for health?

To determine the answer to this question, let’s look at what happens at the cellular and hormonal level when you do intermittent fasting. When you fast, many things happen at the molecular and cellular level.

For example, your body begins to adjust its hormone levels to make all of the stored body fat more easily accessible. Your cells then begin important repair processes and alter gene expression.

Here are some changes that are happening during your fast:

  • Human growth hormone (HGH) levels skyrocket; Sometimes it increases up to 5 times. This leads to muscle gain, and fat loss.
  • Your insulin sensitivity will improve. By fasting, your insulin levels will drop significantly, which helps in getting the stored body fat easier.
  • When you fast, your cells trigger cellular repair. Autophagy is an example of cell repair. In this process, old cells are removed and digested, including inactive proteins that have accumulated inside.
  • Intermittent fasting contributes to changes in gene expression that promote longevity and protection against many diseases.

These changes at the level of cell, hormone and gene expression all contribute to the many health benefits of this fasting method.

Most people try intermittent fasting as you lose weight when you follow this plan. Intermittent fasting reduces calorie intake by eating less food. It directly affects the levels of hormones and insulin which aid in weight loss.

In addition, fasting also helps trigger the release of norepinephrine; A fat burning hormone. Even if you fast for short periods of time, your metabolic rate increases by 3.6 to 14%. By eating fewer calories and burning more calories, you’re effectively changing the calorie equation and promoting weight loss.

Several studies have shown that intermittent fasting is an effective weight loss tool. According to a 2014 study conducted at the University of Illinois at Chicago, intermittent fasting resulted in up to 8% of weight loss over a 24-week period.

This is a remarkable amount of weight loss compared to other methods. The same study found that people who followed intermittent fasting were able to reduce waist and abdominal fat by up to 7%, a known contributor to diseases. The participants in this study were losing about 0.55 pounds each week.

It’s also important to exercise with IF, as it has been proven to help with fat loss and muscle gain. So in short, intermittent fasting can help you lose weight and compensate if you don’t overeat during an acceptable period. In addition to weight loss, it has significant benefits in metabolic health and the prevention of chronic diseases.
