Juice Fasting: 6 Reasons Why it May Not Be Right For You

By Paul Meldrum

Detoxification has been a buzz word around the health and fitness industry. Many people are trying to make up for a lifetime of poor food, stress, drinking and other unhealthy habits with a week of juicing. Although we are not opposed to drinking raw vegetable juices (they are a great source of vitamins and enzymes) we are opposed to them being used in a detoxification strategy. Here are 6 reasons why juice fasting may be a bad idea for you.

1. Unbalanced Liver detoxification

This is a topic that is highly misunderstood. Liver detoxification is a complicated process that is made up of 2 highly distinct phases. Phase 1 is the phase of liver detoxification that our bodies already do remarkably well and is supported by juicing. Where things get tricky is phase 2. This phase deals with actually processing and excreting toxins out of the body and is highly amino acid and nutrient dependent. This is the problem with juice fasts, as amino acids are derived from proteins and juicing does not provide this.
This is the reason why many people feel worse on juice cleanses. They have effectively sped up stage 1 of liver detoxification but stage 2 is actually slowed down leading to a build up of toxins and other nasty things. This can often lead to skin break outs and other unpleasant symptoms.

2. Potential blood sugar instability

One of the keys to health and fat loss is maintaining healthy and stable blood sugar levels. The best way to manage blood sugar is to ensure you eat meals that combine a good mix of the 3 key macronutrients protein, fat and carbohydrates. On a juice fast you will primarily be consuming simple sugars which will elevate blood sugar levels and then send them plummeting down leading to unstable blood sugar.Another thing that can effect this is not consuming enough dietary fibre. When you juice vegetables and fruits you will get all of the sugar but none of the fibre leading to more blood sugar issues.

3. It can be dangerous for some individuals

For some individuals fasting can actually be very dangerous. Avoid fasting if you have a history of blood sugar issues, kidney problems, low blood pressure, gall stones and kidney issues.

4. A fast way to consume lots of sugar

If you want to get lean and healthy one of the main things to do is avoid sugar. On a juice fast this will be your primary source of nutrition! Eating the whole fruit or vegetable is more beneficial due to fibre content.

5. Deficiencies in fats and proteins

As we learnt before protein is essential for optimal detoxification. Fat is also required for many physiological processes including optimal hormonal health. Long term fast will deplete the body of these 2 key macronutrients leading to a lowered metabolism and long term weight gain.

6. Your weight loss will not be permanent

One thing people love about juice fasts is that they lose weight. Unfortunately this is just because they are consuming far less calories than before. As soon as they go back on a normal diet the weight will come right back on. This is a cycle you do not want to get trapped in as it can be very hard to break.

My recommendations

If a client of mine is interested in juice fasting I have no issue with doing it for one day a week. It can be a good way to get some more vegetables in the diet and reduce overall caloric load throughout the week.

A better way to detoxify the body would involve not toxifying it in the first place! Eat high quality lean proteins, drink lots of fluids and consume lots of vegetables and you will be supporting all phases of detoxification, lose weight and be happy and healthy.
