Everything You Need to Know About 48-Hour Fasting

What Is Hour Fast?

Intermittent fasting (IF) is a way of eating in which you eat very little food for several days or weeks at a time. For example, if you were to fast for 8 hours every day, it would take approximately 16 days before your body had used up all the nutrients from those few meals.

The term “hour” refers to how long you are fasting; it does not refer to the number of hours per day. If you were to fast for 12 hours each day, it would take approximately 36 days until your body was completely depleted of nutrients.

A typical IF protocol involves skipping breakfast and lunch, and instead consuming foods such as oatmeal with peanut butter or fruit juice after dinner. Your diet may include small amounts of protein, fat, carbohydrates and other vitamins and minerals depending on what is available in your local area.

Why Do I Want To Fast?

There are many reasons why someone might want to fast. Some people do it because they have health issues like cancer or diabetes, so their bodies need extra time to heal. Others choose to fast because they want to lose weight. Other times, fasting is done for spiritual purposes like praying or meditating. There are even some religious groups that believe fasting will bring them closer to God.

How Long Does It Last? How Many Days Do I Have To Fast? What Are My Results?

The duration of a fast depends on the length of the fast and your personal goals. A fast can last anywhere from 12 hours to several months. Your own personal goals will also influence the length of your fast.

If you want to lose weight during a fast, you can drink only water or juice for a few days. After the first week, you can add low-calorie foods back into your diet like vegetables and broth.

If you are fasting for medical reasons, you should speak to a doctor about the length of your fast. Your physician may want to perform blood tests every few weeks to make sure you are receiving all the nutrients your body needs.

If your body is not getting certain vitamins or minerals, the fast can be extended to ensure complete recovery.

What Are The Risks And Side Effects?

There are several risks and side effects that come with fasting. A few of the most common include lack of energy, headache, dehydration and muscle loss.

If you are fasting for more than a few days, you may suffer from dizziness, irritability and nausea. These negative side effects can lead to depression or thoughts of suicide.

It is important to seek immediate medical attention if you experience these symptoms.

It is also very important that you speak to your physician before you begin any fast longer than three days. They will be able to tell you whether you have any health conditions that would make fasting dangerous.

What Else Do I Need To Know?

The main things to keep in mind when fasting are safety and patience. Fasts can be dangerous, so make sure you don’t push yourself too hard. If you start experiences negative side effects like dizziness or nausea, you should break your fast early.

It can also take your body a long time to get used to not eating, so do not expect immediate weight loss results. Many people actually gain weight in the beginning of a fast because their bodies store fat for later use.

It is not uncommon to not see a difference on the scale for several weeks.

That’s it! Now you are ready to begin your own fast.

Just remember to listen to your body and break the fast if you start experiencing negative side effects.
