The Guide to Intermittent Fasting

Intermittent fasting (IF) is a buzzword you’ve probably heard before — and for good reason. It can provide numerous health benefits ranging from physical to mental. You might be considering IF for weight loss or even clarity of mind. If so, this guide can get you started.


This article will explain what intermittent fasting is and how to get started. You will also learn about what you can and can’t eat during periods of fasting. After this article, you should be well on your way to understanding the process.


The Science Behind Intermittent Fasting (What does it do)?

The benefits of intermittent fasting begin at a cellular level.  When you go for a period without eating, the body begins making changes. Hormone levels increase to start making fat storage more accessible for burning. When the body doesn’t have incoming food for energy, it turns to fat as another source.


Along with additional fat accessibility, there are other changes that go on with the body.


  • Insulin levels drop, which cues the body to begin burning fat.
  • Human growth hormone levels can undergo a dramatic increase. Higher levels of this hormone relate to increased fat burning and muscle growth.
  • Celluar repair begins in the body. This process allows to flush out excess waste. Cellular repair also can change the gene process.

Kicking into Ketosis

Once your body is in a fasted state, Your body enters another state: ketosis.


Ketosis happens when the body does not have enough carbohydrates to burn. Instead, it will burn fat for fuel and energy instead. Ketosis is a popular term that you may have already heard about with a low carbohydrate diet. Think of Atkins or of course the Keto diet. The idea is that the body uses fat as fuel, which can aid in weight loss. 


When you are on a low-carb diet, it can take two to four days to go into ketosis. It depends on the person, or some people can find it happens quite quickly While others it can take a long time. 


Keep in mind that fasting will not necessarily get you into a ketosis state faster. But a fasting regimen can help you go into ketosis more often, making it more effective for weight loss.

What to Eat or Drink When You Try Intermittent Fasting

Can I have cream in my coffee? There are plenty of questions that people ask about what to eat or drink when you’re intermittent fasting.


You’ll have to be careful about what you eat when you are fasting. Sometimes you can unintentionally break your fast without realizing it. Being aware of the proper foods and liquids to consume can prevent ineffective fasting periods later.


So, what can you eat or drink for intermittent fasting?


During the fasting period, the following foods and liquids are allowed:


  • During your fasting, you are allowed to have water. However, it is best to stick to plain water and especially do not choose any sweeteners. Carbonated water is allowed as long as it is unflavored. If you choose flavored water, there is a potential that the sweeteners will break the fast cycle.
  • Tea and coffee are also allowed when you are fasting. But just like water, both tea and coffee need to be consumed without any additives. This means that you need to hold the sugar and cream in your coffee or the milk for your tea. You also cannot add honey to tea, either. Some people find that small amounts of fat in coffee or tea can curb hunger, but be sure you research this before moving forward.
  • Diluted apple cider vinegar is also acceptable during a fasting period.  Adding two teaspoons of apple cider vinegar added to water may help prevent cravings while staying hydrated.
  •  Ingesting healthy fats can also be acceptable while you fast. Think of fats such as coconut oil or butter. An oil breaks fast, but the good news is that it will not take you out of ketosis. 


Carefully studying the food and liquid that is allowed during a fasting phase we’ll save you a lot of headaches down the road. Once you have an idea of what you are allowed to consume during these periods, you can begin considering how to start intermittent fasting.

How to Start Intermittent Fasting

There is no universal way to do intermittent fasting. There are several methods that you can use and they can all be effective. The one that works best will depend on each person and their metabolism, along with a variety of other factors.

16/8 Fasting Method

Made Popular by Fitness expert Martin Berkhan, the 16/18 fasting method has you fasting each day for about 16 hours. Once you enter your 8 hour window, you can eat as normal.


 While not eating for an entire 16 hours may sound challenging, but you can include this timeframe into your sleeping hours. If you sleep for 8 hours at night, half of the battle is already done for your fasting period. You don’t even need for it to be awake for the fasting to take place!


Meanwhile, there are another remaining 8 hours of the day where you will need to steer clear of most foods and liquids. The easiest approach to this fasting method is to stop eating after dinner and Skip your breakfast the next day.


This method can pose a problem to people who are used to eating breakfast. After all, breakfast literally means “break fast”! However, you can help decrease feelings of hunger by drinking black coffee or filling up with water. 

12 Hour Fasting

Another popular option is to fast for an entire 12 hours.


You can fast between the hours of 7 p.m. or 7 a.m. To make this method easy, plan to stop eating at dinner time, go to bed at a reasonable hour, and wake up for breakfast. This way, you won’t have a long time to wait if you want to eat breakfast as normal.


A 12 -hour fasting regimen is a good starting point for people who are new at IF. This is usually a doable amount of time for many people.

With the 5:2 fasting method, this means that you will eat for 5 days during the week. However, 2 days during the week you will not eat anything at all.
