Is Watermelon Good for Diabetics? Here’s the Truth

Is Watermelon good for Diabetics?

Let’s start by clearing the air: yes, people with diabetes can eat watermelon. The important thing is how it fits into the big picture of your overall eating habits.

While watermelon is naturally sweet, it's made up of over 90% water. That makes it low in calories and refreshing on hot days. It's also a source of fiber, antioxidants, and vitamin C. The key lies in moderation and understanding your portion sizes.

So, instead of cutting it out, think of watermelon as one piece of the fruit puzzle—something you can enjoy, as long as you're balancing your intake and keeping variety in mind.

How Does Watermelon Affect Blood Sugar?

Before you give watermelon the side-eye, let’s take a closer look at how it actually affects your blood sugar.

Watermelon has a high glycemic index (GI), which tells us how quickly it can raise blood sugar. But it also has a low glycemic load (GL)—which takes portion size into account. 

That means when eaten in a regular serving (about one cup), it doesn’t cause dramatic spikes in blood glucose for most people.

Pairing it with other foods, like a small handful of nuts or a boiled egg, can help keep your blood sugar more stable after eating.

In short, watermelon can fit into your meals or snacks without worry—as long as you’re mindful of your portions and what you pair it with.

How to Eat Watermelon If You Have Diabetes

You don’t need to avoid watermelon—you just need to enjoy it smartly. Let’s talk about strategy:

Watch the Portion Size

Stick to around one cup of diced watermelon per serving. That keeps you within a healthy range while leaving room for other fruits during the day.

Pair It Wisely

Eating watermelon with a little protein or healthy fat—like a few almonds, low-fat cheese, or Greek yogurt—can slow down how quickly the sugars are absorbed, which helps prevent blood sugar spikes.

Eat It Fresh, Not Processed

Fresh watermelon is best. Watermelon juice and dried watermelon tend to be more concentrated in sugar and stripped of fiber, which makes them less friendly for blood sugar.

The takeaway? A little planning goes a long way in making watermelon work for you, not against you.

And if you're trying to round out your meals with other low-carb, nutrient-rich options, shrimp is a surprisingly great choice—especially when paired with fresh veggies or fruit like watermelon.

Variety Matters More Than Avoidance

When it comes to fruit and diabetes, variety is your best friend—and watermelon deserves a spot in the rotation.

There’s no need to label any fruit as “off-limits.” In fact, the general guideline for people with diabetes is to include up to three servings of fruit per day, spread out across meals.

 Rotating between fruits like apples, berries, pears, oranges, and watermelon ensures you get different nutrients without overdoing it on any one type.

If you're exploring other tropical fruits, you may also be wondering about pineapple. You can read our full breakdown on pineapple and diabetes for more clarity on how it fits into a diabetic diet.

So don’t worry about watermelon being “too sweet.” Just focus on keeping your fruit game balanced and diverse.
