A fruitarian diet plan is an intriguing way to eat more whole, plant-based foods while focusing primarily on fresh fruit. People turn to this diet for its simplicity, natural appeal, and potential health benefits. Proponents of this diet claim it supports weight loss, improved digestion, and increased energy. 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.
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. A fruit diet mostly consists of raw fruits. A person who follows this diet may call themselves a fruitarian.

A fruit diet is a vegan diet made up mostly of raw fruits. People who follow this diet may also eat some vegetables, seeds, and nuts, but they usually eat only raw foods and avoid grains. While there is no strict definition of a fruit diet, people who follow it tend to consume 70-80% of their daily calories from fruits.
A fruitarian diet may include plenty of fruits commonly considered to be vegetables, such as avocados, tomatoes, cucumbers, peppers, olives, and squash.
There is no limit to the amount of fruit that a fruitarian can eat - most people tend to eat as much as satisfies their hunger.
There isn’t one specific way to do the fruit diet. Some fruitarians only eat fruit that has fallen onto the ground, rather than fruits that have been picked. Others won’t eat any seeds, because these have the capacity to become living plants. Fruitarians typically eat freely from multiple fruit groups. You may wish to stick to a three-meal-a-day plan, or build in four to five smaller meals throughout the day.
The fruit groups to choose from include:

- acidic fruits, such as oranges, grapefruit, tomatoes, berries, plums, and cranberries
- sub-acidic fruits, such as apples, apricots, raspberries, and cherries
- oily fruits, such as avocados, olives, and coconuts
- sweet fruits, such as bananas, dates, figs, and grapes
- starchy fruits, such as squash
- melons of all kinds
- vegetable-fruits, such as cucumbers and bell peppers
You should also drink water, coconut water, or 100 percent fruit juice throughout the day.
Can a Fruitarian Diet Support Weight Loss?
Eating more fruit can support weight loss, but a fruitarian diet alone may not be the answer.Fruits are naturally low in calories and high in fiber, which keeps you full longer. Many fruits have a high water content, keeping you hydrated and reducing bloating. 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. Fruits contain fiber, which can help lower your cholesterol and encourage regular bowel movements. Apples, pears, blackberries, and raspberries are examples of fruits high in dietary fiber. Fruits are also an excellent source of dietary fiber. According to the Department of Agriculture, many people in the United States do not eat enough fiber. It is an essential part of any diet and can help reduce the risk of heart disease, lower blood cholesterol levels, improve bowel functioning and reduce constipation, and create a feeling of fullness, which can cause a person to consume fewer additional calories.
- 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.
- 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. Oranges, red peppers, and strawberries are examples of fruits that contain lots of vitamin C. This helps keep teeth and gums healthy. Vitamin C also supports the immune system. Potassium, abundant in bananas, avocados, and cantaloupe, helps regulate blood pressure and muscle function. Bananas, guavas, cantaloupe, and mangos are examples of fruits higher in potassium. Potassium can help maintain a healthy blood pressure and regulate fluid balance in the body. Folate, present in citrus fruits and papaya, plays a key role in cell growth and brain health. Oranges and tropical fruits such as mangos are high in folate. This can help the body produce red blood cells. Folate also supports healthy fetal development. 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 are an excellent source of antioxidants and vitamins - including vitamins that are lacking in a standard American diet. Many fruits contain high levels of vitamin C, which helps repair tissue and maintain healthy gums and teeth, and potassium, which is vital for keeping blood pressure at a healthy level, and folate, which helps the body create red blood cells. Black plums, prunes, and all berries are examples of fruits rich in antioxidants. Antioxidants limit the production of free radicals. They can protect your skin and fight off illness.
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.
A fruitarian diet is very restrictive, excluding a lot of food groups. It does not include the range of nutrients that the body needs for optimal health. A fruit diet is also high in sugar, which may lead to a number of health problems.
- Nutritional deficiencies
The body cannot absorb the nutrients that it needs from fruit alone. Anyone following a fruit diet may be missing out on vital nutrients, including iron, calcium, vitamin D, zinc, omega-3 fatty acids, and B vitamins, including B-12. These nutrients play crucial roles in the functioning of the body. Consuming too few of these nutrients can lead to health problems, such as dry skin and brittle hair, fatigue, low mood, depression, weakened bones, reduced immunity, weakened muscles, and cognitive difficulties. Several nutrients that are vital for overall health are lacking in a fruit-based diet. This includes protein, fat, calcium, B vitamins, and omega-3 fatty acids. Due to the diet’s highly restrictive nature, malnourishment is a significant concern. Your body might even go into starvation mode. This means that your metabolism will slow as it attempts to hold onto your nutritional stores and conserve energy. You may also experience anemia, fatigue, and a reduced immune system. Over time, the lack of calcium can lead to osteoporosis.
Fruitarians frequently have low levels of vitamin B12, calcium, vitamin D, iodine and omega-3 fatty acids, which can lead to anemia, tiredness, lethargy and immune system dysfunction. Low calcium can also cause osteoporosis. Nutritional supplements that fulfill these deficiencies are often made from food sources like dairy cultures or soy protein, which are considered off-limits in the fruitarian diet. This makes malnourishment on the fruitarian diet super common.
- Lack of protein
A lack of protein is one of the main risks of a fruitarian diet. Although a person following the diet may eat some nuts and seeds, these may not contribute sufficient amounts of protein to maintain health. A lack of protein can cause a number of health problems, including swelling, anemia, a weakened immune system, physical weakness, problems with blood vessels, which can lead to cardiovascular diseases, and stunted growth.
- Fructose and the glycemic index
Fruits naturally contain sugar, called fructose, and some have more sugar than others. A type of fruit with more sugar ranks higher on the glycemic index (GI), a scale that measures how quickly specific foods cause blood sugar levels to rise. Fruits with higher GI values include bananas, grapes, and tropical fruits. Fruits with lower GI values have slightly smaller effects on blood sugar. Some of these fruits include apples, oranges, pears, and berries. Regardless of their GI values, all fruits raise blood sugar because they contain carbohydrates. Focusing on portion size and following a balanced diet are two important ways to keep blood sugar levels stable. This can be difficult for people on a fruit diet. Controlling blood sugar levels is vital for overall health and especially important for people with diabetes. A fruit-based diet is likely not a good choice for people with unstable blood sugar levels. To prevent spikes in blood sugar, it is also a good idea to avoiding drinking a lot of fruit juice.
For people with diabetes or prediabetes people, the fruitarian diet can be dangerous. Fruits contain so much natural sugar that eating too much can negatively affect blood sugar levels. A fruit-only diet can also be dangerous for people with pancreatic and kidney disorders.
- Tooth decay
Fruits contain acids, including fructic and citric acids. If a person does not have a good oral hygiene routine, some fruits and fruit products may dissolve tooth enamel, leading to tooth decay over time. Certain fruits are particularly acidic, such as oranges, lemons, grapefruits, and limes. Juices from these and similar fruits are also especially acidic. Drinking 100% fruit juice may increase the risk of developing cavities, according to some research. Rinsing with water after eating acidic fruits can help prevent dental erosion. Overall, however, following a fruit-based diet likely exposes the teeth to more acid than a more inclusive diet would.
Fruit’s high sugar content can put you at high risk for tooth decay. For example, apples have the potential to be as corrosive as candy or soda. Some fruits, such as oranges, are highly acidic and can erode tooth enamel.
People can help reduce their risk of tooth decay by brushing twice a day, flossing, and not brushing immediately after eating, to help prevent enamel erosion.
- Other risks
Shifting from a traditional diet to a restrictive fruitarian lifestyle will require your body to adapt to a different variety of food than you may currently be used to. Don’t switch up overnight. Instead, give yourself a few weeks to adjust gradually.
Restricting your diet to mainly fruits can lead to cravings, food obsessions and disordered eating. By relying mainly on fruits and depriving yourself of needed vitamins, fats and proteins, it’s possible to push your body into starvation mode. If your body feels it’s starving, it will slow down your metabolism in an attempt to conserve energy for vital functions.
The fruit diet can cause hunger, tiredness, dizziness, weakness or fainting due to the low calorie intake. Because it is very restrictive in nutrients and calories, the fruit diet should not be maintained when pregnant or breastfeeding.
Transitioning to a Fruitarian Diet
When you first consider a switch to the fruitarian diet, you should start by building a base. Many of these freeze well if you don’t think you can eat everything before it spoils. You can also create a rotation plan to minimize waste, and get familiar with water-rich fruits vs calorie-dense fruits for snacking.
Taking it slow is a must with restrictive diets. Instead of jumping into the deep end, start by replacing just one cooked or processed meal each day with a fruit-only plate. By the third week, you can try experimenting with a full day of fruitarian eating and see how your body responds. Pay close attention to your energy levels, mood, and digestion. Also, remember to rest when you need to and listen to your hunger cues; never skip meals on the fruitarian diet. You can prevent energy dips by pairing your fruit-centered meal with a handful of nuts or seeds for fat and protein.
If the diet appeals to you, proceed slowly. Rather than start all at once, make a gradual transition away from your current eating patterns. This may mean giving up alcohol, animal products, grains, processed foods, and caffeine. You should also begin adding raw fruits, nuts, seeds, and vegetables.
Overall, fruit-based diets are extremely restrictive and do not provide key nutrients. Also, for some people, following very restrictive diets contributes to an unhealthy relationship with food.
A Balanced Approach
A person can often acquire the benefits of a fruit diet by following a less restrictive diet that is still rich in produce, including fruit. A person can often benefit from following a less restrictive diet that still includes plenty of fruits and vegetables and few, if any, processed foods. A fruit diet is a type of diet that is characterized by primarily eating fruits, which can be supplemented with vegetables, whey protein and lean protein. This diet is high in fiber, which can be beneficial for increasing bowel movements, reducing bloating and keeping you full. The fruit diet was developed by Registered Dietitian, Jay Robb, who stipulates that you should adhere to this diet for 3 day. He states that these days can give the digestive system a break from consuming processed foods. However, there are no scientific studies available that prove the benefits of the fruit diet for health or weight loss. The creator of this diet also recommends exercising at a low intensity, like walking or stretching. This meal plan is just an example of the fruit diet, and can vary depending from person to person depending on their health history and nutritional needs. The fruit diet should be followed for only 3 consecutive days. On the first day of the diet, you should only consume whey protein, vegetables and healthy fats. It is believed that the fruit diet can lead to a weight loss of 9 kg (or 20 lb) in 3 days.
Instead, dietitians always recommend choosing an eating style or diet that you can stick with long-term.
A better dietary approach to being a fruitarian is the Mediterranean diet or a pescatarian diet (which is a vegetarian diet that includes fish). Both include a strong base of fruits and vegetables, along with other plant based foods like nuts, seeds, legumes, plant based oils and whole grains. Both diets limit dairy and sugar.
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.
