A fruitarian diet plan is an intriguing way to eat more whole, plant-based foods while focusing primarily on fresh fruit. Proponents of this diet claim it supports weight loss, improved digestion, and increased energy. From our experience, people turn to this diet for its simplicity, natural appeal, and potential health benefits. But is it sustainable? Can it provide all the necessary nutrients? This guide covers everything you need to know, from the basics of a fruitarian diet plan to a 1-day meal plan, its benefits, its risks, and important considerations. Plus, we’ll answer some of the most common questions to help you learn how to eat more fruit in your diet.
What Is A Fruitarian Diet Plan?
A fruitarian diet plan is a plant-based eating pattern where the majority of your intake comes from raw fruits. Some versions allow nuts, seeds, and a few vegetables, while stricter approaches eliminate everything except fruit.
According to our research, the fruitarian diet is often used as a short-term cleanse rather than a long-term lifestyle. It’s low in fat, rich in fiber, and packed with vitamins, but also lacks some essential nutrients like protein and healthy fats.
Emily Hulse, MS, RD explains, “The fruitarian diet has great intentions - we all want to eat more fruit! But, eating raw fruit alone stops you from eating proteins and fats that are essential for your energy levels, immune system, hormones, and general health. I would recommend eating more fruit - but not fruit alone.” While proponents of the fruitarian diet believe in its claimed benefits, not all Registered Dietitians and nutrition professionals agree on using it in practice.
Can a Fruitarian Diet Support Weight Loss?
Eating more fruit can support weight loss, but a fruitarian diet alone may not be the answer. Here are some benefits of increasing fruit intake in your diet:

- Low In Calories: Fruits are naturally low in calories and high in fiber, which keeps you full longer.
- Hydration Boost: Many fruits have a high water content, keeping you hydrated and reducing bloating.
- No Processed Foods: Cutting out processed foods means cutting out excess sugar, unhealthy fats, and empty calories.
However, relying on fruit alone can lead to muscle loss and nutrient deficiencies over time, so balance is key. Many Registered Dietitian Nutritionists and Certified Nutrition Specialists recommend consuming fruit alongside protein and fat sources to balance blood sugar and keep you fuller for longer. Jessica M. Kelly, MS, RD of Nutrition that Heals, LLC explains, “A fruitarian diet may provide a high intake of vitamins, antioxidants, and fiber, but it lacks essential proteins, healthy fats, and key nutrients like B12, iron, and omega-3 fatty acids. While fruit is a nutritious part of a balanced diet, relying solely on it can lead to nutrient deficiencies and blood sugar imbalances. A well-rounded approach is key to long-term health.”

Benefits Of A Fruitarian Diet Plan
Proponents of this diet claim a fruitarian diet can be a refreshing way to nourish the body with natural, whole foods. From increased energy to better digestion, there are plenty of reasons why adding more fruit to your meals can be beneficial. Here’s a closer look at some potential advantages of a fruit-focused diet:
Promotes Hydration
Staying hydrated is essential for everything from brain function to digestion. Many fruits, especially watermelon, oranges, and strawberries, have a high water content, making them a great way to stay hydrated without relying solely on plain water.
For example, watermelon is over 90% water, which means eating just a few slices can contribute significantly to daily fluid intake. Hydrated cells function more efficiently, which can improve skin elasticity, maintain energy levels, and even help regulate body temperature. Plus, fruit-based hydration is naturally refreshing and free of artificial additives found in many commercial drinks.
Supports Digestion
A well-functioning digestive system is key to overall health, and fruits are loaded with fiber to keep things running smoothly, making them an excellent option for a high-fiber diet plan. Soluble fiber, found in apples, pears, and citrus fruits, absorbs water and helps form soft, easy-to-pass stools.
Insoluble fiber, present in fruits like grapes and bananas, adds bulk to the stool and prevents constipation. Many fruits, including papaya and pineapple, also contain digestive enzymes that aid in breaking down food more efficiently. Eating a variety of fiber-rich fruits can help promote gut health, reduce bloating, and keep the digestive system balanced. As per a study published by Speciale G et al, in 2016 in the journal Nature Chemical Biology, green-leafy vegetables contain sulfoquinovose, a sugar that acts as an energy source for E. coli.
Boosts Energy Levels
Feeling sluggish? Fruits are a natural source of quick and sustained energy. Unlike refined sugars, which cause energy crashes, the natural sugars in fruit provide a steady release of glucose that fuels the body.
Bananas, for example, are an excellent pre-workout snack because they offer easily digestible carbohydrates and potassium, which helps prevent muscle cramps. Dates and figs provide an instant energy boost, making them ideal for mid-afternoon slumps.
With their combination of vitamins, minerals, and natural sugars, fruits can help maintain energy throughout the day without the need for artificial stimulants.
Aids In Weight Loss
For those looking to manage their weight, eating more fruit can be effective alongside other dietary changes. Fruits are naturally low in calories and high in fiber, helping to create a feeling of fullness that reduces overall calorie intake.
Fiber slows digestion, which means blood sugar levels remain stable, reducing cravings and overeating. High-water-content fruits like grapefruit and berries add volume to meals without adding extra calories. Plus, since fruits are naturally sweet, they can help satisfy sugar cravings more healthily, making it easier to avoid processed snacks and desserts. Data from the Nurses’ Health Studies and the Health Professional’s Follow-up Study show that women and men who increased their intakes of fruits and vegetables over a 24-year period were more likely to have lost weight than those who ate the same amount or those who decreased their intake. Berries, apples, pears, soy, and cauliflower were associated with weight loss while starchier vegetables like potatoes, corn, and peas were linked with weight gain.
Rich In Vitamins And Minerals
Fruits provide essential nutrients that support overall well-being. Vitamin C, found in oranges, kiwi, and strawberries, boosts immunity and promotes collagen production for healthy skin. Potassium, abundant in bananas, avocados, and cantaloupe, helps regulate blood pressure and muscle function. Folate, present in citrus fruits and papaya, plays a key role in cell growth and brain health. Eating a variety of colorful fruits ensures the body gets a broad spectrum of vitamins, minerals, and antioxidants, all of which contribute to optimal health. Fruits and vegetables are rich sources of vitamins A, C, E and K and minerals like potassium, magnesium, calcium. They are also a good source of dietary fibers and possess antioxidant properties.
Risks of the Fruitarian Diet
The fruitarian diet may not provide benefits or even be appropriate for everyone - especially depending on your goals and overall health. Eating fruit alone can raise your blood sugar levels, which can lead to or worsen insulin resistance, pre-diabetes, or even type 2 diabetes. In addition, spikes and crashes in blood sugar can lead to feelings of jitteriness, anxiety, stress, brain fog, or other emotions due to fluctuations. Before starting the fruitarian diet, it’s important to speak with your medical team to ensure it’s a good choice for you.
Insufficient Caloric Intake
In the short-term, you may feel uncomfortably full, but still hungry. “Most fruits and vegetables are low in calories and high in volume, due to their fiber and water content,” says Avery Zenker, RD, a registered dietitian in the Toronto, Ontario area. “That means you’d need to eat a very large volume to meet daily energy needs, which isn’t always realistic.”
In the long-term, a lack of calories can lead to malnutrition, excessive weight loss, and muscle mass loss, Zenker says.
Gas and Bloating
If you’re eating just fruits and vegetables, you’ll find yourself consuming a high volume just to feel full. Zenker says this significant increase in volume and fiber may cause digestive woes like excessive bloating, gas, diarrhea, or abdominal cramps when you start your fruits and veggies-only diet.
“In the long-term, if the gut doesn’t adapt to the increase in fiber, digestive symptoms could continue,” Zenker says. Plus, many fruits and vegetables are high in FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides and polyols). Eating high amounts of these fermentable carbohydrates can increase digestive symptoms, particularly in people with irritable bowel syndrome (IBS), Zenker says.
Lack of Protein
Only eating fruits and vegetables means your diet will lack protein, a key component of nutrition. “Without enough protein, you're unable to properly repair and build muscle,” Ayoob says.
Eating more protein in midlife may contribute to better health decades later, with lower odds of major chronic diseases, mental health concerns, and problems with memory or physical function, according to a review published in February 2024 in The American Journal of Clinical Nutrition. Specifically, for every 3 percent increase in calories from protein, researchers found a 5 percent higher odds of healthy aging. Researchers also found that the chances of healthy aging increased by 31 percent for every 3 percent increase in calories from plant proteins.
However, most fruits and vegetables aren’t significantly high in protein, unless you’re including plant-based foods like beans and legumes in the mix, Zenker says.
“Without adequate intake, the body starts breaking down muscle to supply amino acids, leading to health problems including weakness, impaired recovery from injury, and lower immune resilience,” Zenker says.
Iron Deficiency
Plant sources only have non-heme iron, which your body absorbs in much smaller amounts than heme iron that’s found in animal sources.
“Lack of iron can be a concern, particularly for menstruating women, athletes, and growing children,” Zenker says. “Long-term iron inadequacy can lead to anemia, fatigue, hair loss, decreased stamina, and impaired cognition.”
Iron-deficiency anemia is the most common nutrient deficiency globally, affecting 30 percent of people. Poor diet often is the cause, and it can lead to inflammatory conditions like chronic kidney disease, inflammatory bowel disease, and heart failure.
Lack of Other Key Nutrients
Omega-3s (a type of healthy fat) are not present in fruits and vegetables in their long-chain forms - eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), Zenker says. Instead, they primarily contain alpha-linolenic acid (ALA), according to the National Institutes of Health Office of Dietary Supplements. Your body can convert some ALA into EPA and DHA, but usually only small amounts. Cold-water fatty fish is the richest source of EPA and DHA.
“Low EPA and DHA over time is linked to problems such as higher inflammation, mood disorders, and increased cardiovascular risk,” Zenker says. Omega-3-rich foods may help lower the risk of chronic health conditions, including heart disease, rheumatoid arthritis, certain cancers, preterm birth, and depression.
Only eating fruits and vegetables could also lead to other deficiencies, Zenker says. No single fruit or vegetable provides all of the nutrients you need to be healthy.
Conclusion
Eating more fruit can be a refreshing and nutrient-rich way to focus on whole, plant-based foods. A diet rich in fruit offers benefits like hydration, improved digestion, steady energy, and essential vitamins and minerals. However, a fruitarian diet alone may not provide benefits or be appropriate for you - it does come with risks.
While eating more fruit can support weight loss and overall well-being, it’s important to approach it with balance and ensure you’re meeting all your nutritional needs. Listening to your body and consulting a Registered Dietitian is key to success.

Fruitarian Diet Plan (FAQs)
How much weight can I lose after a 7-day fruitarian diet plan?
A fruitarian diet may lead to quick weight loss due to a lower calorie intake and water weight loss. However, this is not sustainable and weight will often be re-gained once you begin eating more foods. To find a sustainable approach to weight loss, connect with a Berry Street Registered Dietitian for customized advice tailored to your health.
Can I eat unlimited fruit and lose weight?
Not necessarily. While fruits are low in calories, they still contain natural sugars. Eating excessively could lead to high sugar intake, which might slow weight loss or impact blood sugar levels.
Our expert Registered Dietitians recommend adding protein and fat sources to your fruit intake to help stabilize blood sugar levels, provide more energy, and keep you full for longer in between meals.
