Dietitian's Tips for Consuming Grapefruit Juice (Squeezed)

  • Metabolic Effect: Grapefruit juice can raise blood sugar levels quickly due to its natural sugars. Its low fiber content may result in a short-lived feeling of fullness, leading to faster hunger.
  • Consumption Recommendation: Instead of consuming grapefruit juice alone, pair it with protein and fiber-rich foods like a handful of almonds or a few pieces of cheese to balance blood sugar levels. This combination helps you stay full for longer.
  • Things to Consider: One glass of grapefruit juice is approximately equivalent to one serving of fruit. Especially for diabetics, it is important to remember that grapefruit juice can rapidly increase blood sugar levels. Additionally, it may interact with some medications, so it is important to consult your doctor.
  • Exercise Equivalent: To burn the 78 calories in one glass of grapefruit juice, you need to walk briskly for about 16 minutes. This can help maintain your daily energy balance.
