16-8 Intermittent Fasting: What You Need to Know

16-8 intermittent fasting is a method in which an individual stays off food and any calorie-containing drinks for 16 hours a day, consuming them within a period of 8 hours daily. It is sometimes referred to as the 16:8 plan or diet. 

In this article, everything an individual needs to know about intermittent fasting will be discussed.

Fasting is a process that has significant religious meaning, but it is also vital in many cultures. In recent times, people have gone on fasting in order to lose weight. 16/8 intermittent fasting is a kind of fasting method embarked on by most individuals for the sake of losing weight. It has been reported to be a sustainable, easy, and convenient method to lose eight. Intermittent fasting is also said to improve the overall health of an individual. The belief is that a 16-8 plan assists an individual’s internal clock, the body’s circadian rhythm.

Depending on an individual’s preference, this method can be done gradually. An individual can begin by doing this fasting once or twice a week and then every day as they progress. During the 16 hours of abstaining from food, an individual can always drink water. The individual may also take non-caloric beverages such as tea or plain coffee.

When it is time to eat, nutritious whole foods such as whole grains, fruits, unsweetened tea, veggies, eggs, and fish can be eaten.

Getting Started on 16-8 Intermittent Fasting

Following a 16/8 intermittent fasting routine is quite simple, flexible, and less restrictive. Compared with other forms of diets, 16/8 intermittent fasting may only disrupt the diet to a minimum level, giving measurable results in the process. 

Before starting this routine, an individual should choose an 8-hour period that they must stick to. Food should be eaten during this period. People can always experiment with the best time that will suit their lifestyles. Usually, the 16-hour fasting period should be one’s sleeping time. Eating hours can fall in the middle of the day. The best practice is to avoid eating food 2-3 hours before sleeping. To help tick to the chosen time, an individual may decide to set timers. Some preferred times by people are:

  •  9 am to 5 pm
  • 10 am to 6 pm
  • 12 pm to 8 pm
