Facts About Intermittent Fasting

Intermittent fastingSome people want to lose weight because they are not comfortable with the way that they look in the clothes they wear, others are concerned about their overall health. Regardless of the reason, there are many different types of diet programs on the market today. One of which involves intermittent fasting.

For people who want to know what intermittent fasting is and what it entails, here’s a brief overview about this topic that will answer some common questions.

What is Intermittent Fasting?

Fasting is not a new method of controlling one’s daily diet regimen, it has been used in the past for numerous things. Some have used fasting for healing various kinds of illnesses and diseases, cleaning out the digestive system, religious purposes and a wide variety of other things.

Today, fasting is being modified to accommodate another way of dieting, especially since it is now being used to lose weight and maintain the weight loss. This form of dieting is more commonly called “Intermittent Fasting”.

Intermittent fasting can be described as scheduling a specific time that an individual will go without food. The actual timing of the fast for each person is often different since some people may go without food for 12 hours, a full day, several days, and even a week.

Why intermittent fasting?

People are attracted to intermittent fasting for numerous purposes. Since there are many different health benefits of going without consuming foods for short and extended periods of time, people can select the reason or reasons that fit their situations best.

For example, those who choose the shorter daily intermittent fasting options, will often discover that it helps them to be more consistent in their overall eating habits. Therefore, they do not have to follow a complex diet program that’s too hard to keep up with throughout their day (i.e. the dieter must buy specific breakfast foods, lunch foods, snacks and dinner to follow it correctly).

Intermittent fasting is also beneficial for people who tend to have problems controlling their eating. Specifically, for those who find themselves wanting to eat continuously throughout their day without a break. By using intermittent fasting, the body is also being trained to adapt to hunger since the feeding times are more consistent instead of sporadic.

Does fasting do something for you beyond weight loss? Does it reduce the risks of heart disease, Alzheimer’s disease, dementia and cancer? The promises are BIG, but these promises are not yet, fully supported by scientific research in humans.

How does it work?

How does intermittent fasting work? The type of intermittent fasting that a person chooses can vary from one person to another. Since some people may choose daily intermittent fasting, while another dieter chooses weekly intermittent fasting as their program. However, once this option has been chosen, the person can begin to follow the best practices that will work best for them. For instance, if the individual has chosen daily intermittent fasting, they may be fasting for health.

With daily intermittent fasting, the individual may set a schedule that allows them to eat between the hours of 12:00 – 5:00 p.m. Which means, they can eat anything that they want to between these hours, while they are fasting the other hours of their day. Further, when people are also trying to lose a certain amount of weight, most health professionals recommend that they eat only real foods during these times.

Therefore, they will need to eliminate any snacks that they would normally eat when they feel hungry. By eliminating the snacks, it helps the individual with controlling their appetite, empty calories consumed and increases the nutritional value and vitamins in their body.

Fasting versus Detoxing

Detox planEven though fasting can be used as a method to rid the body of certain harmful bacteria from the body, it is not considered to be a fad detoxing procedure. The distinction between a fast diet plan and a detox diet plan can be quite evident, specifically when it comes to the timing.

In fact, most people do this for an overnight quick weight loss effect that is not really expected to last. On the other hand, with intermittent fasting, people are looking to correct certain body ailments and diseases and lose the weight long-term.
