9 Tips for Juice Fasting Success

1. Prepare for the Fast  

Before jumping into a juice fast, you should prepare your body. If you jump right into your fast from an unhealthy diet, you may feel sick from the detox symptoms.

To properly prepare for your fast, we recommended transitioning from your regular diet to a cleaner diet with raw fruits and veggies. You should also focus on eating smaller portions than usual and eating only to satisfy your hunger. You should also incorporate regular, non-strenuous exercise into your routine while drinking enough water to flush out the toxins in your body.

Preparing for your fast will help reduce the side effects of fasting such as nausea, extreme hunger, fatigue, and more. 

2. Plan Your Recipes 

Planning your recipes before starting your juice fast will help you research and be prepared in the kitchen during your fast. Our Juicing Companion book can be very helpful during this process – you can use it to learn which fruits and vegetables are great for your juicer meet your specific health needs.

Here are a few ingredients with great health benefits to jump start formulating your recipes: 

Kale – antioxidant, anti-inflammatory, helps arthritis and autoimmune diseases
Green Apples – anti-inflammatory, antioxidant, reduces inflammation, lowers cholesterol, and increases energy
Ginger – aids in digestion, reduces pain, improves the immune system
Cucumber – lowers blood pressure, promotes healthy skin, prevents some forms of cancer

3. Caloric Intake 

Doing a juice cleanse may reduce the number of calories in a person’s diet, which can lead to weight loss during a juice fast.

Sounds great, right? Well, reducing your caloric intake may lead to dangerous territory. After an extended period of time without your favorite foods, you might feel like you need to reward yourself after your juice fast is over. Having this mindset might set you back from gaining some of the great benefits from your fast. 


4. Lack of Protein  

Our bodies need protein to maintain and build muscle mass, make us feel full, and so much more. When eaten, fruits and vegetables contain low amounts of protein and can leave us hungry while potentially decreasing our muscle mass. This is one of the dangers of juicing, but it is avoidable by making sure to incorporate lots of veggies that have higher protein.

When doing a juice fast, consider drinking a homemade nut-milk beverage (cashew or almond) in between your routine beverages. Also, juicing dark green vegetables will increase your protein consumption.

Take for example these raw veggies and the amount of protein in 227g /8oz serving per ESHA Genesis nutrition database:

  • Kale: 7g protein
  • Watercress: 5g protein
  • Broccoli: 5g protein
  • Baby spinach: 5g protein
  • Cabbage: 3g protein

5. Going All In Right Away 

Before starting a juice fast, you should slowly work your way into your fast. This means replacing a meal with a fresh-pressed juice until you’ve phased out solid food entirely. Slowly integrating juice into your diet will help you from jumping into your juice fast and prevent shocking your body and leaving you tired and starving. 

6. Hydration Is Important 

Hydration is king. Making sure that your body is well hydrated during your juice cleansing is very important. We recommend drinking warm lemon water during your fast – plus, water will help you fight off hunger between juices! 

7. Choose Your Fruit and Vegetables Wisely 

When juice fasting, aim to choose organic fruits and vegetables due to the lower amounts of pesticides. In addition to lower amounts of pesticides, organic produce includes around 20-30% higher levels of antioxidants and 50% less heavy metals. When consuming exclusively fresh fruit and vegetable juice, you should consider the potential pesticides that are in your food. 

8. Workout Routine 

Exercising is an important part of any diet, but when juice fasting you should try to conserve as much energy as possible. While juice fasting, you should follow your instincts and try not to overdo it and make sure to listen to your body before overworking yourself. 

9. Slowly Breaking the Cleanse 

When you are nearing the end of your cleanse after one to three days, you want to slowly integrate solid foods into your diet. You can do this by drinking smoothies, eating watery fruit, and other soft foods such as oatmeal.

This is a great time to go back and revisit your intentions for your juice fast. If you’re trying to understand your food intolerances, make sure you keep this in mind when integrating food back into your diet. Move slow and track everything you’re eating so you can easily pinpoint what bothers your body. We recommend continuing to hydrate – you can do this buy drinking lemon water, herbal tea, green juice, and more. 

If you were looking for a “restart” or body detox, make sure to focus on yourself and plan your post-fast meals as much as possible with healthy raw and whole foods. This will help you avoid gravitating towards processed foods and unhealthy snacks after completing your fast. 

At Goodnature, we love doing juice fasts to deep clean and flush our bodies of toxins, but we think it is highly important to fast safely. We hope our tips will help encourage and educate you during your fasting journey!

Hi Sage, I totally agree! Just fasting is much easier when you prepare for it or if you are already eating mainly plant-based. Good luck on your next juice fast, let us know how it goes 😄
