A fruitarian or fruit diet promotes the intake of fruits and nuts and seeds in their natural forms. Some vegetables that are classified as fruits, such as avocados and tomatoes, are also allowed (2). The diet also severely restricts other food groups like animal products and grains.

One benefit of this diet is that it does not require a lot of meal preparation. Also, the elimination of unhealthy fats and inclusion of fiber-rich foods may help improve metabolic health (3).

Some fruitarians only eat fruits that have naturally fallen off the trees rather than plucking them.

The benefits of a fruit diet can be appealing. But before you embark on it, you need to know how it works. Learn more in the next section.

How Does The Fruit Diet Work?

The fruit diet works on the following principles:

  • Consumption Of Fruit

The diet primarily focuses on consuming a wide variety of fruits like apples, bananas, berries, citrus fruits, etc. Some fruitarians even prefer organic or locally sourced fruits as they are believed to contain lower levels of chemicals and preservatives.

  • Exclusion Of Major Food Groups

A strict fruitarian diet excludes or severely limits other food groups like animal products (meat, dairy, eggs), grains, legumes, and processed foods. The sustainable and eco-friendly nature of this diet also appeals to people.

The fruit diet is flexible and allows you to customize it as per your preferences and health goals. In the next section, we have discussed how you can follow this diet.

How To Follow The Fruitarian Diet

Start by eliminating the following food groups, one by one, from your diet. This gradual progression will allow your body to adjust to the changes and ensure you can adhere to it easily.

  • Alcohol
  • Dairy products
  • Seafood
  • Animal products
  • Legumes
  • Processed foods
  • Caffeine
  • Carbonated drinks

You can slowly start adding the following foods to your diet:

  • Fresh, unprocessed fruits
  • Nuts
  • Seeds
  • Vegetables

Focus on getting more than 50% of your daily calories from fruits and the rest from vegetables, seeds, and nuts. Follow this diet properly to enjoy the following benefits.

How The Fruit Diet Benefits Your Health

  • It Boosts Your Nutrient Intake

A fruit diet is rich in vitamins A, B6, C, and E, iron, phosphorus, zinc, and fiber (4). These nutrients help improve metabolism and even boost cognitive function (5), (6), (7).

  • May Improve Digestion

The high fiber content in fruits may help improve gut motilityi  XThe movement of food from the mouth, throat, esophagus, stomach, small and large intestines, and out of the body and reduce constipation, abdominal pain, and bloating (8), (9).

  • May Boost Cardiovascular Health

Intake of fruits like apples, grapes, pomegranates, blueberries, avocados, etc. may improve lipidi  XFatty compounds that are a part of the cell membranes and help maintain cell structure and energy storage levels and reduce inflammation. This may help improve your heart health and reduce the risk of stroke (1).

  • May Slow Down Aging

Fruits like oranges, berries, grapes, and cherries are rich in antioxidantsi  XNatural or man-made compounds that help combat free radicals in the body and delay cellular aging and bioactive compounds that may help combat oxidative stress, slow down cellular aging, and improve overall skin health (10).

  • May Aid In Weight Management

Fruits are generally low in calories and high in water and fiber. This may help improve metabolic health and aid in weight management. The phytochemicalsi  XChemical compounds found in plants that may help reduce the risk of diseases like diabetes, cancer, and heart issues in fruits were found to lower fat mass and help reduce obesity risk (11).

  • May Reduce Gastric Cancer Risk

The high antioxidant and vitamin C content in fruits may suppress the growth of gastric cancer (12). However, more research is warranted in this regard.

It is recommended that you consult a doctor or dietitian for a customized diet plan. Also, while the fruit diet offers many benefits, it also may pose certain risks. Learn about them in the next section.

Potential Risks Of The Fruit Diet

  • May Lead To Nutritional Deficiencies

The fruit diet eliminates major food groups. This may lead to deficiencies of protein, omega-3 fatty acids, iron, zinc, and vitamin B12 (2). These deficiencies, as a consequence, can cause reduced appetite and night blindnessi  XA type of vision impairment where people have trouble seeing well at night or dimly lit places like movie theaters and increase the risk of anemiai  XA condition that develops due to lack of red blood cells and can lead to fatigue, pale skin, and dizziness , depressioni  XA mood disorder characterized by a persistent feeling of sadness, changes in appetite, and loss of interest , and dementiai  XLoss of memory, thinking, and problem-solving ability that interfere with your daily life activities (5), (13).

  • May Result In Obesity-Related Diseases

A fruit diet is high in simple sugars and may increase the risk of weight gain and heart disease in certain individuals (11). However, whether this effect applies to other individuals is yet to be studied.

  • May Not Be Sustainable

The fruitarian diet is highly restrictive as it eliminates major food groups. This makes it difficult to sustain.

  • May Spike Blood Sugar Levels In Some Individuals

The high sugar content in oranges and bananas may elevate blood sugar levels. Hence, this diet may not suit those with diabetes (2).

protip_icon Pro Tip
The recommended daily intake for protein is 0.8 grams for every kg of your body weight (14). Consume plenty of nuts and seeds to make up for your daily protein requirement (15).

You now know the benefits and potential risks of this diet. However, the possible advantages can be appealing. But how long do you need to wait before you can see results?

How Long Does The Fruit Diet Take To Show Results?

A study published in the journal Nutrients discusses how increased fruit intake led to a significant reduction in body mass index and waist circumference in obese participants after 8 weeks (11).

Another study found that eating 2 or more servings of fruits per day may reduce the risk of stage-1 hypertensioni  XA medical condition where the blood force against the artery walls is so high that it increases the risk of stroke and heart disease thanks to their rich potassium content (16), (17).

However, there is no information on the duration it may take before one can see results from this diet. Also, the limited options available and its restrictive nature make this diet suitable only for the short-term. Consult a doctor or registered dietitian for a customized diet plan to ensure your nutritional needs are met.

The fruit diet focuses on the intake of fruits, nuts, and seeds while excluding all other food groups. It may help improve cardiovascular health, slow down aging, and aid in weight loss. However, its restrictive nature may cause nutritional deficiencies and may not suit those with diabetes. Hence, consult a healthcare professional or registered dietitian for a sustainable diet plan to ensure your nutritional needs and health goals are met.

Frequently Asked Questions

How long can I follow a fruit diet?

The duration may vary from person to person and is based on an individual’s health and nutritional needs. Consult a dietitian for more clarity in this regard.
