Summer in Hong Kong means scorching heat and an irresistible urge to reach for chilled, refreshing fruit. Many of us assume that swapping meals for fruit is a surefire way to stay healthy and slim. But according to Taiwanese dietitian Cheng Hanyu, that assumption can be dangerously misleading. In a recently shared ranking of 18 popular summer fruits by calorie content, Cheng reveals that some fruits pack enough energy to rival—or even exceed—a bowl of white rice. The biggest surprise? Watermelon, often wrongfully blamed for weight gain, lands at the very bottom of the list.
The High-Calorie Offenders
Topping the chart is durian, the so-called “king of fruits.” Just 100 grams—roughly two modest segments—delivers 132 kilocalories, equivalent to nearly three-quarters of a standard bowl of rice. While durian is rich in vitamin C and folate, its high carbohydrate and fat content makes it a calorie bomb for anyone watching their weight.
In second place comes sugar apple (釋迦), also known as custard apple, with 104 kcal per 100 grams. This sweet Taiwanese favourite is incredibly high in vitamin C—a single serving can meet your daily needs—but eating a whole fruit can be like consuming two bowls of rice. Third is the humble banana at 85 kcal. Though prized for its potassium and convenience, one banana is enough for a snack; a second could tip your calorie tally.
Mid-Range Fruits: Moderation Matters
The middle tier—places four through twelve—includes fruits that are neither diet destroyers nor free passes. Cherries (75 kcal), longan (72 kcal), and lychee (65 kcal) all contain moderate calories but are easy to overeat due to their small size and addictive sweetness. Ten lychees, for example, add up to 130 kcal.
Passion fruit (64 kcal) stands out for its exceptionally high dietary fibre, which promotes gut health. Grapes (64 kcal) offer anthocyanins for antioxidant benefits, while kiwi (56 kcal) is a vitamin C powerhouse. Pineapple (53 kcal) contains bromelain to aid digestion, apple (51 kcal) provides satiety, and red dragon fruit (50 kcal) supports bowel regularity.
The Low-Calorie Champions
For those on a diet, the bottom six fruits are a blessing. Mango (42 kcal) may be lower in calories than assumed, though its sugar content still warrants caution. Peach (39 kcal) is naturally low in sugar and delightfully juicy. Guava (38 kcal) is a dieter’s dream: high in fibre and vitamin C, it keeps you full longer. Melon (香瓜, 37 kcal), snow pear (34 kcal), and finally watermelon (33 kcal) round out the list. Watermelon, composed mostly of water, is the ultimate summer refresher with negligible calories.
Cheng’s ranking underscores a critical lesson: not all fruit is created equal when it comes to calorie density. While fruit remains a healthy choice overall, portion control is key, especially with the heavyweights. As the mercury rises, consider choosing low-calorie options for guilt-free hydration—and save the durian for an occasional treat.
