One of the latest fads is going on a juice cleanse or detox diet, with the intention of flushing toxins from your system. You might not realize that this can be an unhealthy choice.

Looking for a great way to lose weight fast? You might be tempted to try a juice cleanse or detox diet. These latest fads have many fans. The idea of completely cleaning out your insides sounds very enticing. However, it might not be very good for you. While reducing your calorie and fat intake can help you lose weight, these drastic measures can affect your blood pressure, among other things.

Here are five reasons that you should avoid juice cleansing or detox diets.

1. It’s not a long term solution.

Although a strict juice cleanse will help you lose a few pounds very quickly, the effects won’t last long. Lauren Harris-Pincus, M.S., RDN, owner of Nutrition Starring You, LLC, states, “Anyone can follow a restrictive diet or cleanse for a certain period of time. Unfortunately, data shows us that, when the diet ends, most people gain back everything they lose plus more.”

2. You will feel lousy.

Many of the detox plans, especially the juice cleanses, dramatically reduce your intake of fat and protein. This can be a problem, because these two nutrients are responsible for creating neurotransmitters in your body, which help stabilize your mood. And, when you drop your calorie intake too low, you will have far less energy.

3. You will lose muscle mass.

When you limit your protein intake, you will lose muscle mass. Over the course of only one week, you can lose up to one pound of muscle per week! Harris-Pincus states, “Then, when the weight comes back, it will most likely be gained as fat.”

4. You are removing fewer toxins than you think.

In reality, our bodies naturally detoxify themselves. Harris-Pincus states, “Our bodies were designed to detox themselves. Our liver and kidneys already do a great job of removing waste and toxins from our bodies.” In order for your body to run optimally, eat healthfully and make smart choices that include lots of fruits and vegetables, whole grains, nuts, seeds, beans, and lean proteins. Avoid sugar and processed foods.

5. You will waste a lot of money.

Most juice cleansing programs are pretty pricey—you could spend up to $200 for a 3-day cleanse. You can get a lot of wholesome, nutritious food for that amount of money!

Instead of using a juice cleanse or detox program, make healthy choices for every meal and snack!
