Is it OK to drink juice for weight loss?

Juice has become a popular drink for those looking to lose weight due to its nutritional benefits. Some juices are low in calories and high in nutrients, which may help boost weight loss. However, drinking juice can also have downsides when it comes to achieving and maintaining a healthy weight. Here is an in-depth look at whether drinking juice is advisable for weight loss.

The potential benefits of juice for weight loss

There are a few reasons why juice may aid weight loss when consumed in moderation:

  • Some juices are low in calories. For example, a cup of cranberry juice has only 117 calories, which is significantly lower than a sweetened soda at around 150 calories per can.
  • Juice can boost your intake of important vitamins and minerals. Certain nutrients like vitamin C and magnesium may help support metabolism and fat burning.
  • The high water content in juice can help hydrate the body and increase feelings of fullness.
  • Fruit and vegetable juices provide beneficial plant compounds like antioxidants and polyphenols which may help reduce inflammation and oxidative stress.

Given these nutritional attributes, replacing high-calorie beverages like sodas and sports drinks with low-calorie juices can support a calorie deficit needed for weight loss. Juice may also help curb cravings for sweet drinks and provide more overall nutrients than hydrating with water alone.

Potential downsides of juice for weight loss

However, there are some potential downsides to consider when drinking juice for weight loss:

  • Juice is lower in fiber since the pulp is removed during processing. Fiber helps promote fullness and gut health.
  • Without the fiber, juice is not as filling and may lead to consuming more calories overall.
  • Juice spikes blood sugar rapidly due to its high glycemic index. This can lead to hunger and cravings soon after drinking it.
  • Some fruit juices are high in calories and sugar similar to sodas, like apple or grape juice.
  • Pre-packaged juices often contain added sugars, preservatives, and other questionable ingredients.
  • Juice is not as hydrating as water and the hydration from juice may be short-lived.

Overall, drinking high amounts of juice can potentially lead to excess calorie intake which could counteract weight loss efforts. Moderation is key when incorporating juice into a diet.

Best juices for weight loss

Some juices may be better suited for weight loss goals due to their nutrition profiles. Here are some top juices to consider:

1. Cranberry juice

Cranberry juice is very low in calories and sugars. It provides antioxidants including anthocyanins which give cranberries their deep red color. Cranberry juice has been studied for its potential to aid weight loss and reduce body fat.

2. Tomato juice

Tomato juice is low in sugar and calories compared to other vegetable juices. Tomatoes provide fiber, vitamin C, potassium, and lycopene, an antioxidant linked to lower risk of chronic diseases.

3. Carrot juice

Carrot juice is nutrient-dense, providing vitamin A, vitamin K, vitamin C, folate, potassium, and manganese. Carrots also contain carotenoids which may help reduce inflammation.

4. Green juice

Green juices made from leafy greens like spinach, kale, and parsley are low in calories, high in vitamins, and packed with antioxidants. The fiber content is also higher than fruit juices.

5. Beet juice

Beets provide antioxidants and nitrates which may help lower blood pressure and improve athletic performance. Beet juice is low in sugar and calories.

Guidelines for juice intake

To maximize the benefits of juice while limiting potential downsides, here are some intake guidelines:

  • Consume no more than 1 cup (8 oz) of juice a day. Higher amounts may lead to excess sugar and calorie intake.
  • Choose 100% fruit juices without added sugars or sweeteners.
  • Make your own juice at home using whole fruits and vegetables to control ingredients.
  • Pair juice with protein, healthy fats, or fiber from whole fruits, vegetables, nuts, seeds, eggs, etc. to increase satisfaction.
  • Drink juice alongside meals rather than on its own between meals.
  • Consider diluting juice with water or seltzer to reduce calories and sugar content.
  • Limit fruit juice and opt more for low-sugar vegetable juices for weight loss.

Following these guidelines can help ensure juice is enjoyed moderately and compliments an overall healthy diet geared for weight loss.

The bottom line

Here is a summary of whether it is advisable to drink juice for weight loss:

  • Juice can provide important vitamins, minerals, and antioxidants that may benefit weight loss.
  • However, juice is low in fiber, less filling than whole fruits and veggies, and can spike blood sugar.
  • Drinking high amounts of juice and juice alone often can lead to excessive calorie intake which hinders weight loss.
  • 100% vegetable and fruit juices low in sugar are best for weight loss.
  • Juice intake should be limited to 8 oz per day and always consumed alongside fiber, protein, and fat for optimal health effects.

Overall, pure vegetable and fruit juices can be included as part of a healthy weight loss diet when consumed in moderation. While juice should not be relied on as a meal replacement, it can be a low-calorie way to hydrate and provide extra vitamins and minerals if portion sizes are controlled.

Frequently asked questions

1. Is juice better for you than soda?

In general, 100% fruit or vegetable juice is healthier than soda. Juice provides more vitamins, minerals, antioxidants, and water compared to soda which contains added sugars and no fiber content. However, soda and some juice are similar in calories and sugar per serving. For health and weight loss, plain water is best.

2. Will I lose weight by only drinking juice?

It is not recommended to follow a juice-only diet for weight loss, especially long-term. Juice-fast type diets can cause nutrient deficiencies over time since juice lacks adequate protein, fat, and fiber. For sustained weight loss, juice should be included as part of a balanced diet of whole foods.

3. Is store-bought or homemade juice better?

For the healthiest juices with no added sugars, preservatives or questionable ingredients, homemade juice is best. But for convenience, low-sugar store-bought brands can fit into a weight loss diet. Always check the label when purchasing juices.

4. What is the healthiest juice to drink daily?

The healthiest juices to drink daily are vegetable and greens-based juices like tomato, carrot, beet, cucumber, spinach, or kale juice. They provide plenty of nutrients for relatively few calories and little sugar. Limit fruit juice intake to a couple times per week due to the higher calories and sugar content.

5. Can juice help flatten your stomach?

There is no evidence that drinking juice alone flattens your stomach. Weight loss achieved through diet and exercise will help reduce overall body fat, including on the stomach area. Drinking juice can aid weight loss as part of a balanced calorie-controlled diet and active lifestyle.

Sample juice-based meal plan

Here is a sample 1-day meal plan incorporating juice to promote weight loss:


  • 1 cup carrot juice
  • 2 scrambled eggs
  • 1 slice 100% whole wheat toast with 1 tbsp natural peanut butter


  • Tuna salad made with 3 oz tuna, lettuce, tomato, 1 tbsp olive oil mayo
  • 1 cup green juice


  • 1 oz mixed nuts
  • 1 cup sliced bell peppers and celery


  • 3 oz salmon baked in foil with lemon and herbs
  • 1 cup roasted broccoli and cauliflower
  • 1 cup cranberry juice

This meal plan provides a good balance of protein, healthy fats, fiber, and nutrient-dense juices. The juices are paired with fiber and protein which promotes satiety. Aim for a similarly balanced approach when incorporating juice into your own diet.


Drinking small amounts of low-calorie, low-sugar vegetable and fruit juices can be part of a healthy weight loss diet. Focus on homemade juices or read labels carefully when purchasing store-bought juice. Juice should not replace water intake and must be consumed in moderation, always accompanied by fiber, protein, fat, and whole fruits and veggies for optimal nutrition and weight loss effects.
