The Complete Guide to Intermittent Fasting

The Complete Guide to Intermittent Fasting

1. WHAT IS INTERMITTENT FASTING?

Fasting has been practiced across the globe in various religions and cultures for thousands of years. Recently the ancient practice of fasting has taken on new twists making it a very popular health and fitness trend.

It is known in the health and fitness world as intermittent fasting.

Intermittent fasting (IF) is a cyclic eating pattern that alternates between periods of fasting and eating. It is important to note that IF does not specify what types of food you should eat, rather focuses on when you should eat them. Intermittent fasting resembles more of an eating pattern than a diet because there are no calorie restrictions.

The various methods of intermittent fasting schedules include;

  • 16:8 Method
  • 5:2 Diet
  • Eat-Stop-Eat Method
  • Alternate - Day Fasting
  • Warrior Diet

Amongst the various types of IF methods, the most popular style of fasting is the 16:8 method, which consists of a 16 hour fast.. Many intermittent fasters state that the 16:8 method is easy, convenient, and sustainable, increasing its appeal.

2. 16:8 INTERMITTENT FASTING?

16:8 intermittent fasting is a pattern of eating that allows you to have an 8 hour window of eating, and a 16 hour fast. A 16:8 IF can be repeated as often as you like, anywhere from daily to once or twice per week, depending on your personal preference.

Out of all of the different intermittent fasting methods, this method is considered the least restrictive and most flexible.

While there are many health benefits from 16:8 fasting, studies have shown that it can be particularly beneficial for athletes. Our article “Everything you need to know about intermittent fasting 16:8discusses these benefits in detail. 16:8 IF has also been shown to have additional health benefits including weight lossimproved blood sugar, and increased brain function.

3. HOW TO INTERMITTENT FAST...

The first thing you should know about how long to intermittent fast and the 16:8 method, is that it is safe (assuming you do not have any underlying health conditions), simple, and sustainable. To get started, the first thing you need to do is pick an 8-hour window where you will consume your entire food intake for the day. Remember that your food intake should be limited only to your 8 hour window.

Many people schedule their 8 hour window of eating between noon and 8 PM. By doing so, you only fast overnight and skip breakfast. The time frame in the noon to 8 PM fast allows you to enjoy two balanced meals and a few snacks throughout the day.

Another popular time frame is an eating window of 9 AM to 5 PM. This option allows for a healthy breakfast around 9 AM, a normal lunch around noon, and a light early dinner or snack around 4 PM before your fast begins from 4 PM to 9 AM (next day).

Both fasting options allow adequate time for you to consume nourishing and healthy meals.

It doesn’t matter which option you choose, however consistency is important.

In order to maintain blood sugar levels, and keep hunger under control, it is important that the meals and snacks you consume are spaced evenly throughout your 8 hour eating window.

In order to ensure that you are receiving the adequate amount of nutrients, it is also equally vital that the type of food and beverages consumed during the 8 hour period are nutritious and whole.

Every meal and snack should include a variety of whole foods such as:

  • Protein: Meat, poultry, eggs, fish, legumes, nuts, seeds, seafood.
  • Healthy fats: Olive oil, coconut oil, avocados.
  • Whole grains: Quinoa, brown rice, buckwheat, barley.
  • Vegetables: Cauliflower, kale, spinach, broccoli, cucumbers
  • Fruit: Bananas, apples, berries, oranges, pears.

It is important to note that during the fasting period, drinking non-caloric beverages is allowed. In fact, maintaining good hydration may also help curb hunger during the fasting period. Calorie free beverages such as water, unsweetened tea and coffee are good sources of hydration. Though 16:8 intermittent fasting does not have any food restrictions, binging on junk food can negate any positive effects that 16:8 intermittent fasting may have.

Therefore, make sure that you plan ahead to ensure that your 8 hour window of eating is filled with whole and nutritious foods, rather than fast food.

4. HEALTH BENEFITS OF FASTING

The simplicity, and convenience of 16:8 intermittent fasting makes it a very popular “diet.” Individuals following this eating pattern have found that the amount of time and money committed to food and preparation each week reduced once incorporating IF into their daily routines.

Simplicity and convenience aren’t the only benefits of 16:8 intermittent fasting. There are numerous health benefits associated with this eating pattern as well, such as:

  • Increased Weight Loss: According to several studies published by the International Journal of Obesity, research has found that intermittent fasting for weight loss, even for a few hours per day, helps to decrease caloric intake as well as enhance the metabolism and increase weight loss.
  • Improved Blood Sugar:2014 study found that intermittent fasting lowers blood sugar levels and reduces fasting insulin, which may help decrease the risk of diabetes.
  • Enhanced Longevity: Preliminary research found that short-term, repeated fasting was an effective tool in prolonging the life span in mice.

    5. INTERMITTENT FASTING MEAL PLAN
