A juice fast until dinner is a type of intermittent fasting where you consume only fruit and vegetable juices until your first meal of the day, which is dinner. This allows your body to enter into a fasting state during the day, giving your digestive system a break while still providing nutrients from the juices. Juice fasts are sometimes done as part of a cleanse or detox program. Here is a comprehensive guide to juice fasting until dinner, including the benefits, what to expect, and how to do it safely and effectively.
What is Intermittent Fasting?
Intermittent fasting is an eating pattern that cycles between periods of fasting and eating. Rather than restricting what you eat, it restricts when you eat. One of the most popular types of intermittent fasting is time-restricted feeding, where you limit your eating window to 6-8 hours per day. The remaining 16-18 hours are your fasting period.
Some examples of time-restricted feeding schedules include:
- 16/8 method: Fast for 16 hours per day, eat within an 8 hour window.
- 20/4 method: Fast for 20 hours, eat within a 4 hour window.
- Eat-Stop-Eat: Do a 24 hour fast once or twice per week.
Juice fasting until dinner follows a similar concept, restricting all calorie intake until dinner time to create an extended daily fasting period. This allows your body to enter into a fasted state which may provide health benefits.
Benefits of Juice Fasting Until Dinner
Juice fasting until dinner may offer the following benefits when done occasionally as part of a healthy lifestyle:
- Weight loss: By restricting calories for most of the day, juice fasting can help reduce overall calorie intake to promote weight loss.
- Reduced inflammation: Fasting for 16-20 hours gives your digestive system a rest, allowing inflammation to subside.
- Enhanced detoxification: Your liver and kidneys get a break from processing food and can focus on eliminating toxins.
- Increased insulin sensitivity: Fasting may improve the body’s response to insulin and blood sugar control.
- Boosted immunity: Short term fasting periods may help boost immune function.
- Longevity: Some research shows intermittent fasting may extend lifespan by slowing aging.
- Heart health: Fasting may improve blood pressure, cholesterol and triglycerides.
Choosing Your Fasting Window
When juice fasting until dinner, you’ll need to determine the duration of your daily fast. For beginners, a 14-16 hour fast is recommended. More experienced fasters may work up to an 18-20 hour fast. Here are some sample fasting windows you can follow for juice fasting until dinner:
|Fasting Window||Fast Duration||Sample Schedule|
|Beginner||14-16 hours||Finish dinner by 8pm and break your fast at 10am or noon the next day.|
|Intermediate||16-18 hours||Finish dinner by 6pm and break your fast at 10am-12pm the next day.|
|Advanced||18-20 hours||Finish dinner by 6pm and break your fast at 12-2pm the next day.|
It’s best to break your fast gradually with a light snack before eating a full dinner. Pay attention to your body and aim for the longest fasting window that leaves you feeling energized.
Preparing for a Juice Fast Until Dinner
Here are some tips to prepare both mentally and physically before your juice fast:
- Set your intention: Decide on your goals, such as detoxing, weight loss, or regulating blood sugar. This will help motivate you.
- Make a meal plan: Plan out which fresh juices and light snacks you will have to get enough nutrients.
- Stock up on produce: Shop for plenty of fresh fruits and veggies to juice, like leafy greens, citrus fruits, carrots, apples, and beets.
- Get proper rest: Get at least 7-8 hours of sleep the night before you begin.
- Hydrate: Drink extra water leading up to the fast.
- Exercise: Continue your regular exercise routine, but take it easy during the fast. Lower intensity is better.
It’s generally not recommended to do a juice fast for more than 3-5 days. Seek medical advice if you have any health conditions or take medication.
Choosing Produce for Fresh Juices
Making your own juices from fresh fruits and veggies allows you to control the ingredients and avoid added sugars. Focus on variety to get a wide range of vitamins, minerals, and antioxidants. Here are some great options:
- Leafy greens: Kale, spinach, chard, lettuce
- Cruciferous veggies: Broccoli, cauliflower, cabbage, brussels sprouts
- Colorful veggies: Carrots, beets, sweet potatoes, peppers, tomatoes
- Citrus fruits: Oranges, grapefruit, lemons, limes
- Other fruits: Apples, grapes, pears, melons, berries
- Herbs & spices: Ginger, mint, basil, parsley, cinnamon
Try mixing green veggies with sweeter fruits and aim for at least one serving of green juice per day. You can also add nutrient boosters like wheatgrass, spirulina, and moringa powder.
Sample Juice Fast Schedule
Here is a sample one day schedule for juice fasting until dinner:
|7:30-8:00am||Hot lemon water|
|12:00pm||Fruit juice or coconut water|
|5:00pm||Herbal tea or broth|
|6:30-7:00pm||Light snack to break fast|
Aim for a minimum of six 8oz servings of fresh juice per day. You can drink water, herbal tea, or broth in between juices. Listen to your body and have an extra juice if you feel weak or dizzy.
Foods to Break Your Fast
It’s important to break your juice fast gradually to avoid shocking your digestive system. Here are some healthy foods to break your fast before eating a full dinner:
- Fresh fruit like berries or melon
- Vegetable crudités
- Bone broth or vegetable soup
- Avocado toast on sprouted grain bread
- Nut butter on raw veggies or rice cakes
- Chia pudding with plant milk
- Oatmeal with fruit and nuts
- Hummus with raw veggies
Focus on getting vitamins, minerals, fiber and plant protein to nourish your body without overloading it. Avoid heavy meats, fats, or processed foods when breaking your fast.
Tips for Successful Juice Fasting
Follow these tips to help you have a successful juice fast until dinner:
- Drink juice slowly instead of gulping it down
- Rinse your mouth with water between juices to avoid taste fatigue
- If you feel dizzy or nauseous, sip electrolyte water
- Get light exercise like yoga or walking to energize
- Rest and relax as much as possible
- Avoid stressful activities or environments
- Keep your environment cool to prevent feeling overheated

Be prepared for some side effects like headaches, fatigue, or mood changes, especially in the first few days as your body adjusts. These should resolve as you become more accustomed to fasting.
To make your juice fast as safe as possible:
- Consult your doctor first if you take medication or have any medical conditions
- Don’t juice fast if you are underweight, malnourished, pregnant, or breastfeeding
- Drink enough juices to meet your fluid needs based on your activity level
- Supplement with electrolytes if experiencing symptoms like dizziness, muscle cramps, or headaches
- End your fast if you have severe hunger, fatigue, weakness, or feel unwell
- Transition slowly back to eating regular foods after 1-2 days of eating light
Juice fasting until dinner should only be done occasionally for a few days at a time, not as an ongoing diet. Make sure you are eating a balanced, whole foods diet when you are not juice fasting.
Potential Risks and Side Effects
Juice fasting may lead to the following side effects:
- Hunger, mood changes, irritability
- Headaches, dizziness, fatigue
- Nausea, stomach discomfort
- Hypoglycemia in diabetics
- Nutrient deficiencies if done long-term
You may also experience caffeine withdrawal if you normally drink coffee or tea. Withdrawal side effects tend to improve after a few days as your body adapts.
Frequently Asked Questions
Can I exercise while juice fasting until dinner?
Light exercise like yoga, walking, or gentle stretching is fine during a juice fast. However, high intensity or endurance exercise is not recommended, as you may feel weak or dizzy due to the calorie restriction. Listen to your body and rest as needed.
Will I lose muscle mass if I juice fast?
It’s possible to lose some muscle mass when fasting for more than a couple days, since protein intake is reduced. Consuming plant-based proteins like pea protein powder or spirulina in your juices can help minimize muscle loss while fasting.
Is juice fasting safe long-term?
No, extended juice fasts beyond 5 days are not recommended. You may become deficient in important nutrients like protein, fatty acids, iron, zinc, and vitamin B12 if juice fasting long-term. Keep juice fasts short-term.
Can I drink coffee while juice fasting until dinner?
It’s best to avoid coffee, tea, and other caffeinated beverages when juice fasting. Caffeine is dehydrating and may exacerbate side effects like headaches or dizziness. Stick to water, herbal tea, and fresh juices.
Will I gain all the weight back after ending a juice fast?
If you return to unhealthy eating habits after juice fasting, then you may regain the weight. The best way to keep weight off long-term is to follow a nutritious whole foods diet and exercise plan after ending your juice fast.
The Bottom Line
Juice fasting until dinner when done occasionally can be a safe way to give your body a reset and reap potential benefits like improved detoxification, blood sugar regulation, weight loss, and reduced inflammation. But be sure to keep juice fasts short term, break your fast gradually, listen to your body, and consult a healthcare provider if you have any concerns.
Moderation and balance are key – juice fasting should not replace eating a nutritious diet on a regular basis. But it can be integrated into an overall healthy lifestyle for periodic cleansing and wellness.
