Dietitian's Tips for Consuming Watermelon Juice

  • Metabolic Effect: Watermelon juice provides a rapid energy boost due to its quickly absorbed sugar content. However, since it has almost no fiber, it can cause rapid spikes and subsequent drops in blood sugar. This is especially important for individuals with diabetes.
  • Consumption Recommendation: Instead of drinking watermelon juice alone, it is better to consume it with a snack containing healthy fats or protein, such as a handful of nuts. This helps to maintain a more stable blood sugar level.
  • Things to Consider: One glass (200 ml) of watermelon juice is approximately equivalent to 1 serving of fruit. Consuming excessive amounts throughout the day can lead to excess calorie intake and weight gain. Also, pay attention to the amount of added sugar in some commercial watermelon juices.
  • Exercise Equivalent: To burn the 39 calories from a watermelon juice, about 10 minutes of light-paced walking is sufficient. This is an activity you can easily integrate into your daily life.
