Lychee, also known as litchi or lichee, is a beloved summer fruit, celebrated for its juicy, sweet, and refreshing qualities. Whether enjoyed fresh, blended into smoothies, or tossed into salads, lychee adds a burst of flavor to any dish. However, concerns about its sugar content often make people hesitant to include it in their diet. This article explores the potential weight loss benefits of lychee fruit, its nutritional profile, and how to incorporate it into a healthy eating plan.
What is Lychee?
The lychee (Litchi chinensis) is a small, tropical fruit belonging to the soapberry family, which also includes rambutan and longan. Originating from subtropical regions, particularly China and Southeast Asia, lychees are prized for their sweet and floral flavor. The fruit features a bright, pink-red, leathery skin that is peeled away to reveal a white, translucent flesh surrounding a dark seed. Lychees are versatile and can be enjoyed fresh or processed into juice, wine, sherbet, and jelly.
Nutritional Profile of Lychee
Lychees are primarily composed of water and carbohydrates, offering a range of vitamins, minerals, and antioxidants. According to nutritional data, a 3.5-ounce (100-gram) serving of fresh lychees provides:
- Calories: 66
- Protein: 0.8 grams
- Carbs: 16.5 grams
- Sugar: 15.2 grams
- Fiber: 1.3 grams
- Fat: 0.4 grams
Lychees have a relatively low glycemic index (GI) of 50, and a glycemic load of about ½ cup of lychee is 7.6. Foods with a low GI are digested slowly, leading to a gradual release of sugar into the bloodstream, which helps prevent blood sugar spikes.
Carbohydrates and Fiber
Lychees are mainly composed of carbohydrates, with a single lychee containing approximately 1.5-1.7 grams. The majority of these carbs come from sugars, contributing to the fruit's sweet taste. While lychees do provide some fiber, the amount is not particularly significant.

Vitamins and Minerals
Lychees are a good source of several vitamins and minerals, including:
- Vitamin C: Lychees are rich in vitamin C, with one lychee providing around 9% of the Reference Daily Intake (RDI). Vitamin C is a powerful antioxidant that supports the immune system and protects against chronic diseases.
- Potassium: This essential nutrient in lychees supports heart health and helps maintain healthy blood pressure.
- Copper: Lychees contain copper, an essential mineral that may have beneficial effects on heart health.
Antioxidants
Lychees are a good source of various plant compounds with antioxidant properties. They have been reported to contain higher levels of antioxidant polyphenols compared to other common fruits. Key antioxidants found in lychees include:
- Epicatechin: A flavonoid that may improve heart health and reduce the risk of developing cancer and diabetes.
- Rutin: Another flavonoid that might protect against chronic diseases like cancer, diabetes, and heart disease.
- Oligonol: A dietary supplement derived from lychee skin and green tea, known for its antioxidant properties. Studies suggest that Oligonol supplementation may reduce abdominal fat, fatigue, and inflammation after exercise. However, it is important to note that Oligonol is not naturally found in lychees, so these specific health effects may not be obtained from eating the fruit alone.
Lychee and Weight Loss
While lychees alone are not a magical weight loss solution, they can be a valuable addition to a balanced diet and exercise plan. Eating more fruits and vegetables, including lychees, can support weight loss and promote a healthy weight.
Low in Calories and High in Fiber
Lychees are relatively low in calories and high in fiber, which helps promote satiety and keeps you feeling full for longer periods. This can reduce overall calorie intake and support weight management.
Hydration
Lychee is a super hydrating fruit, making it an excellent choice for hot summer months. Maintaining adequate hydration is crucial for overall health and can also aid in weight loss by promoting fullness and boosting metabolism.

How Many Lychees Should You Eat?
Consuming lychees in moderation is key to reaping their benefits without experiencing any adverse effects. Dietitian Shweta J Panchal suggests that consuming around 10-12 lychees a day is generally safe, as this amount is unlikely to exceed the recommended sugar and calorie intake while providing essential nutrients. For individuals with diabetes, it is advisable to reduce the number of lychees to 5 or 6 per day. Eating about 10 lychees (100 grams) provides approximately 66 calories and 15 grams of sugar.
Potential Downsides of Lychee Consumption
While lychees offer numerous health benefits, there are a few potential downsides to consider:
High Fiber Content
Due to their high fiber content, eating too many lychees can cause digestive issues such as bloating and gas.

Lychee-Associated Encephalopathy
Lychee fruit has been linked to clusters of illnesses in children in India and elsewhere in South Asia. The theory is that in poorly nourished children, a compound in lychees known as hypoglycin A can cause blood sugar levels to drop suddenly, leading to brain inflammation. However, some reports suggest pesticides also play a role in the outbreaks. The illnesses appear during lychee harvest times, when children who otherwise get too little to eat might gorge on lychee fruit, including unwashed and unripe fruits.
Allergic Reactions
Lychee fruit contains some proteins that can lead to rare allergic reactions. Symptoms may include hives, itchiness, swelling of the lips and tongue, and difficulty breathing.
Drug Interactions
Some extracts from lychees, particularly from an inner layer of the fruit called the pericarp, might increase bleeding risks associated with drugs such as aspirin, warfarin, heparin, ibuprofen, and naproxen, and with supplements such as Ginkgo.
Diabetes Concerns
Some substances in lychee fruit might have the potential to lower blood sugar. But limited research done on people has involved extracts of lychee seeds, not the fruit itself. There's no evidence that eating the fruit is either a problem or especially beneficial for people with diabetes.
Tips for Buying and Storing Lychees
- When buying fresh lychees, choose heavy, red fruits.
- Avoid eating the peel. To get to the edible white fruit, break the skin with your thumbnail and peel it off. Then, cut through one side of the fruit to expose the pit, which you can remove with your fingers.
- You can refrigerate fresh lychees for 5-10 days.
- They can also be frozen whole with the peels on.
- Dried lychees can be stored for up to 1 year at room temperature.
Lychee vs. Litchi
Lychee fruit is also known as litchi -- they're the same thing. The fruits are also sometimes called lychee nuts, especially when they're dried.
Is a lychee a berry?
While lychee may look like a big strawberry and grows on a tree that's a member of the soapberry family, it's not a berry. It's a type of fruit called a drupe, which is a simple fleshy fruit with a single pit containing the seed. So, it's in the same family as plums, apricots, peaches, and nectarines.
What do lychee nuts taste like?
The fresh fruit has a sweet, floral flavor. Some compare it to the smell of roses. When dried, it's more like a raisin, with a more intense, acidic sweetness.
