What is Fasting?

Fasting is defined as going without food and/or water for a lengthy period. This can be for a single meal or over an extended period.

For much of recorded history, fasts have been a feature of societies, medicine, and religion. They have long been a part of the human condition.

Types of Fasting?
  • Juice Fasting – Juice Fasting is eliminating foods and substituting them with fresh juices, with many of these relying largely on less sugar-rich vegetables.
  • Dry Fasting – Fasting without food or water is known as dry fasting. Dry fasts are normally for extremely short periods, such as 24 hours, because the body does not function well without water for an extended period. However, these types of fasts are quite effective. One-day water fast can provide the same health benefits as three-day water.
  • Intermittent fasting entails intermittent eating, as the name implies. There are numerous variations, ranging from fasting every other day to skipping one meal per day and all in between.
  • Partial fasting entails abstaining from some foods for some time. This can include meat, processed foods, or simple carbohydrates.
  • Calorie Restriction – Not a full fast, but limiting overall caloric intake for a specific period.

How to Do a 3-Day Fast

Set yourself up for success with proper planning and preparation.

  • Eat a low-carb/low-sugar diet in the days leading up to your fast to assist your body transition to ketosis more quickly and comfortably.
  • Eat smaller meals for several days before to your fast to help your body adjust to eating less food.
  • Cut back gradually on stimulants like sugar, coffee, alcohol, or cigarettes in the weeks leading up to your fast to reduce your dependency.
  • Do not overeat before beginning your fast. The more you consume, the longer it will take your body to enter ketosis. Stick to a small, balanced dinner in the early evening and then immediately begin fasting.
  • Always consult your doctor first, especially if you have a medical condition or are taking medication.
The Fasting Period
  • A true 3-day fast consists of consuming only water for 72 hours, with no other liquids or food.
  • If you work during the week, begin fasting on Friday and end it on Sunday. So, on Thursday evening, have your last meal, and on Sunday evening, break your fast.

This will allow you to rest and relax throughout the weekend when you may not be feeling well.

It will also help you avoid the temptation of being around other individuals who are eating food.

  • Schedule your fast such that you have a 72-hour period between your last and first taste of food.
  • Make time in your schedule to rest and prevent stress.
  • You may experience bouts of weariness and weakness, followed by spurts of vigor.
Breaking the Fast
  • Always eat a light meal or snack to break your fast. For example, you may have bone broth with a small salad or avocado.
  • Your first meal should have a low glycemic index.
  • Avoid carbs and sweets, which might cause you to regain any lost weight and knock you out of ketosis.
  • For at least three days after your fast, avoid caffeine, alcohol, and heavy meals.
  • It is vital to understand that when you fast, your stomach produces less hydrochloric acid (HCI) because there is no food to break down.

Therefore, when you resume eating, give your stomach some time to adjust. If you consume too many calories, fats, and acidic foods, you may overproduce HCI and experience unpleasant acid reflux.

Everyone’s water fasting experience is unique. Some people, for example, suffer from insomnia, whereas others sleep soundly.

In general, you can expect day one of your fast to be the simplest in terms of food cravings. However, you may endure headaches and poor energy levels on the first day, particularly if you are also experiencing caffeine withdrawal.

The hunger pangs will be more intense by day two. On the second day, you may also notice some brain fog and more obvious ups and downs in your energy levels.

By day three, you should notice that your body is less puffy, bloated, and irritated. The hunger may be gone, or it may be worse. Some people have a rough third day, with an insatiable appetite and significant mood changes.
