What You'll Learn
The fruit diet is a subset of the vegan diet
The fruit diet, also known as fruitarianism, is a highly restrictive subset of the vegan diet. It involves eating mostly or all fruit, with 50-75% of foods consumed being raw fruits. Some fruitarians eat freely from multiple fruit groups, while others only eat fruit that has fallen naturally from a plant. While fruit is nutritious and healthy, a diet consisting of only fruit can lead to nutritional deficiencies, especially in children.
Fruitarians may fill the rest of their diets with nuts and seeds, which can provide protein and fat. However, it is important to note that nuts and seeds are technically considered fruits of plants. Fruitarians may also consume vegetables, with some sources recommending raw or lightly steamed vegetables such as sweet potatoes and celery.
The fruit diet is generally low in calories but high in nutrients and vitamins. Fruits are also high in antioxidants, which can help protect the body from oxidative stress and lower the risk of certain chronic medical conditions. However, some fruits are high in sugar and should be avoided or limited when trying to lose weight.
Despite the nutritional benefits of fruit, health and nutrition experts do not recommend a fruit-only diet as it restricts other healthy food groups. This can lead to nutrient imbalances and an increased risk of nutritional deficiencies, such as reduced intake of vitamin B12, calcium, iron, zinc, omega-3, and protein. Maintaining a fruit-only diet over a long period can be dangerous, and it is not suitable for children, nursing mothers, or their babies.
Before starting any diet, it is important to consult a registered dietitian or a doctor to ensure that it is safe and suitable for your individual needs.

It can lead to serious cravings and bingeing
A fruitarian diet is a subset of a vegan diet where participants eat mostly or all fruit. The diet is very restrictive, and the risk of malnourishment is high. It can lead to serious cravings and bingeing, which can cause adverse health effects and disrupt efforts to follow a healthy diet.
Fruit is nutritious and healthy, but it lacks vegetables, grains, dairy, protein, and oils. The body craves extra food on a diet because it wants more energy. Calories are a unit of energy, and not getting enough calories throughout the day can increase the frequency and strength of cravings. A 2020 review of animal studies suggests that eating protein can suppress appetite and reduce ghrelin, a hormone related to appetite.
A fruit diet should be followed for only 3 consecutive days, with a total intake of 900 to 1000 calories per day. However, when followed for more than 3 days, this diet can lead to nutritional deficiencies or increased blood sugar levels. It is very restrictive in nutrients and calories and should not be maintained when pregnant or breastfeeding. It is also not recommended for older adults, children, adolescents, or people with certain health conditions.
Before starting any diet, it is important to consult a registered dietitian for a full assessment and customized meal plan. A health professional can help design an eating plan that will work for your individual needs. It is also important to understand how many calories to consume daily, which varies based on age, gender, body type, level of physical activity, and other factors.
Some tips to help manage cravings include staying hydrated, getting enough sleep, and including high-protein foods in your diet. It is also important to fill up on fibre-rich carbohydrate foods like fruit, root vegetables, and cruciferous vegetables.

It is not a healthy eating plan
A fruitarian diet involves eating mostly fruit and restricting other food groups. While fruit can be a healthy part of a nutritious diet, a fruitarian diet is not a healthy eating plan.
Firstly, the fruitarian diet is one of the most restrictive diets, and an unbalanced way of eating. It lacks vegetables, grains, dairy, protein, and oils. This means that it does not adhere to USDA guidelines for a balanced diet and is not a safe long-term dietary strategy. Restricting your diet to such a limited range of foods means you are unlikely to achieve a balanced diet and are at risk of malnutrition.
Secondly, the fruitarian diet can lead to nutritional deficiencies. Fruits are high in natural sugars, so some people may gain weight when they start to eat high quantities of fruit. The diet can also lead to anaemia, tiredness, and a weakened immune system. The natural sugar in fruit, fructose, when consumed at excessive levels, may be associated with digestive issues and possible dental erosion.
Thirdly, the fruitarian diet can cause hunger, tiredness, dizziness, weakness or fainting due to the low-calorie intake. It proposes a total intake of 900 to 1000 calories per day. This is far below the recommended daily intake of 1,500 calories for weight loss and 2,000 calories for weight management.
Finally, the fruitarian diet can lead to serious cravings for other foods, which may cause bingeing or other forms of disordered eating. It can also cause extreme sensitivity to fat content in foods.
Before starting any diet, you should consult a doctor or a registered dietitian. They can help you design an eating plan that will work best for you.

It can lead to nutritional deficiencies
The fruitarian diet is a subset of the vegan diet, where participants eat mostly or all fruit. It is one of the most restrictive eating patterns, and the risk of malnourishment is high despite the nutritional quality of most fruits.
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.
Vitamin B12, a bacterial product, cannot be obtained from fruits. According to the U.S. National Institutes of Health, "natural food sources of vitamin B12 are limited to foods that come from animals." 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 should be followed for only three consecutive days. It proposes a total intake of 900 to 1,000 calories per day. However, when followed for more than three days, this diet can lead to nutritional deficiencies or increased blood sugar levels.

Consult a doctor or dietitian before starting
Before starting a fruit-only diet, it is highly recommended that you consult a doctor or a registered dietitian. This is because a fruit-only diet is a very restrictive diet that can lead to nutritional gaps and deficiencies. Consulting a doctor or dietitian can help you understand your individual risks and ensure that you are meeting your nutritional needs without putting your health at risk.
A fruit-only diet restricts other healthy food groups and can lead to nutrient deficiencies. It is high in natural sugars and low in protein, healthy fats, and other nutrients vital for overall health. As such, it is not recommended by health and nutrition experts. A registered dietitian can help you design an eating plan that will work for you and ensure you have no nutritional gaps. They can also help you understand how many calories to consume daily, which is important for weight loss, weight management, or weight gain.
If you have an underlying medical condition or take any medications, consulting a doctor is especially important. A doctor can help you modify the diet to suit your individual needs and help prevent any adverse effects on your overall health. For example, the fruit diet should not be maintained when pregnant or breastfeeding. It is also not recommended for older adults, children, adolescents, or people with a history of anemia, osteoporosis, or problems with the heart, kidneys, liver, or gallbladder.
Additionally, a fruit-only diet may not provide you with enough energy to exercise, which is necessary for a healthy body. Consulting a doctor or dietitian can help you determine if a fruit-only diet is safe for you and if any modifications need to be made to meet your nutritional needs. They can also advise you on how to transition to the diet in a healthy way, such as gradually transitioning away from your current eating patterns and including other foods or supplements to balance out the nutritional deficits.
