You’re standing in the pantry. The container of Medjool dates is staring at you. They look like wrinkled, oversized raisins, and they taste like pure caramel. You eat one. Then another. Before you know it, you’ve downed six. Honestly, most of us have been there, thinking it’s just fruit, right? But here is the thing: a proper dates serving size is way smaller than your appetite probably wants it to be.
It’s easy to trick yourself. We’ve been told for years that natural sugar is "good" sugar. While that is mostly true because of the fiber, dates are basically nature's candy bars. They are incredibly calorie-dense. If you’re trying to manage your weight or keep your blood sugar from spiking into the stratosphere, you need to get real about how many you’re actually putting away.
The Reality of the Dates Serving Size
So, what is the actual number? If you look at the USDA data or most nutritional labels, a standard serving is roughly 40 grams. For the massive, fleshy Medjool dates most people buy at Costco or specialty grocers, that translates to just two dates.
Two. That’s it.
If you are eating the smaller, firmer Deglet Noor variety, you might get away with five or six. But let’s be real—most of us are reaching for the big ones. Eating just two feels like a cruel joke when they taste that good. However, those two little fruits pack about 130 to 140 calories and roughly 32 to 35 grams of sugar. To put that in perspective, a standard Snickers bar has about 25 to 27 grams of sugar. You’re essentially eating a candy bar’s worth of glucose and fructose in two bites.
Now, don't get me wrong. I’m not saying dates are bad. They are loaded with potassium—more than a banana, actually—and they have decent amounts of magnesium and Vitamin B6. But the dates serving size is a strict boundary for a reason. Dr. Robert Lustig, a pediatric endocrinologist and author of Fat Chance, often discusses how the fiber in whole fruit helps mitigate the "sugar hit" to the liver. Dates have fiber, which is great. But they have so much sugar that even that fiber can only do so much heavy lifting if you eat ten of them.
Why Medjool and Deglet Noor Aren't the Same
People treat all dates as equals. They aren't.
Medjool dates are the "King of Dates." They are soft, moist, and have a much higher moisture content than other varieties. Because they are so large, the calories per fruit are high. If you’re tracking your macros, you absolutely have to weigh them. A single Medjool can weigh anywhere from 20 to 35 grams. If you eat three large ones, you’ve blown past the recommended dates serving size and hit nearly 200 calories.
Deglet Noor dates are the "bread date." They are firmer, slightly smaller, and a bit more "nutty" than sweet. Since they are smaller, you get more "volume" for your serving. If you’re the type of person who needs to feel like they are eating a lot of something, switch to Deglet Noor. You’ll get to chew on five or six of them for the same caloric hit as two Medjools. It’s a psychological win.

The Glycemic Impact: What Happens When You Overdo It?
There is a common misconception that dates have a high Glycemic Index (GI). Surprisingly, they don't. Most studies, including research published in the Nutrition Journal, suggest that dates have a low GI, typically ranging between 42 and 50. This is because the fiber slows down the absorption of the sugar.
But there is a catch.
Glycemic Index only tells you how fast the sugar hits your bloodstream. It doesn't tell you the total amount of sugar. That’s where Glycemic Load (GL) comes in. If you stick to the recommended dates serving size, the GL is moderate. If you eat a bowl of them while watching Netflix, your blood sugar is going to spike regardless of the fiber. This is especially vital for people with Type 2 diabetes or insulin resistance. You can’t just point at the "low GI" label and eat an unlimited amount.
I've talked to athletes who use dates as "pre-workout fuel." It makes sense. They provide a quick burst of energy. But for someone sitting at a desk all day? That energy has nowhere to go. It just gets stored.
Digestion and the "Fiber Trap"
Dates are famous for helping with "regularity." They have about 6 to 7 grams of fiber per 100 grams. That’s awesome for your gut microbiome. However, if you aren't used to a high-fiber diet and you suddenly decide to triple the standard dates serving size, your stomach is going to punish you.
Bloating. Gas. Cramps.
The sorbitol (a sugar alcohol) naturally found in dates can also have a laxative effect in large quantities. This is why some people use date juice or syrup as a natural remedy for constipation. But as a daily snack? Stick to the two-date limit unless you want to spend a lot of quality time in the bathroom.
Practical Ways to Stick to the Serving Size
It’s hard to stop at two. It really is. The trick isn't willpower; it’s strategy.
Don't eat them plain.
If you eat two dates on their own, you’ll be hungry again in twenty minutes because of the insulin response. Instead, pair your dates serving size with a protein or a healthy fat.
- Stuff them with a teaspoon of almond butter or tahini.
- Wrap a date in a small piece of prosciutto (if you’re into that sweet/salty thing).
- Chop them up and throw them into a giant bowl of Greek yogurt.
When you combine the sugar in the dates with fat and protein, it slows down digestion even further. You feel fuller. You’re less likely to go back into the kitchen for "just one more."
Dates in Cooking: The Hidden Calories
This is where people really get tripped up. The "refined sugar-free" movement has made dates the darling of the health food world. You’ll see recipes for "Raw Vegan Brownies" or "Energy Balls" that use dates as the binder.
Be careful.
Just because a brownie is sweetened with dates doesn't mean it’s "low calorie." In fact, date-based desserts are often much higher in calories than their traditional counterparts because dates are so dense. When you blend 20 dates to make a crust for a tart, you aren't just getting "fruit." You’re getting a concentrated dose of sugar. If you’re eating a slice of that tart, you might be consuming the equivalent of four or five servings of dates in one sitting.
Always check the math. If a recipe says it makes 10 energy balls and uses 20 Medjool dates, one ball is your entire dates serving size for the day.
Real-World Evidence and Expert Nuance
A study conducted by researchers at the Sultan Qaboos University in Oman looked at the consumption of dates among people with diabetes. They found that eating three dates a day didn't significantly impact blood glucose levels over the long term, provided the rest of the diet was controlled. This supports the idea that the dates serving size isn't a "hard no" for people watching their sugar, but rather a "be careful" zone.
However, the variety matters. The study specifically looked at local varieties like Khalas and Bo Ma'an. If you are eating imported, commercially glazed dates (yes, some brands add extra sugar syrup to make them shinier), all those health benefits go out the window. Always look for "no added sugar" on the label, though honestly, most high-quality dates don't need it.
The Micronutrient Argument
Why bother with the serving size at all? Why not just eat a strawberry? Well, dates offer things other fruits don't. They are a powerhouse of polyphenols—antioxidants that protect your cells from oxidative stress. They contain selenium, which is crucial for immune function, and copper, which helps with iron absorption.
If you are pregnant, there is actually some fascinating research (published in the Journal of Obstetrics and Gynaecology) suggesting that eating six small dates a day in the final four weeks of pregnancy might help with cervical ripening and reduce the need for induced labor. Even in that specific medical context, there is still a limit. No one is telling you to eat the whole bag.
Actionable Steps for Date Lovers
If you want to enjoy dates without sabotaging your health goals, follow these specific steps:
- Buy them with the pits in. It forces you to eat slower. You have to mindfully remove the pit, which prevents the "hand-to-mouth" mindless snacking that happens with pitted dates.
- Weight them once. Use a kitchen scale just one time to see what 40 grams of your favorite brand looks like. It’s usually much smaller than you think. Once you see it, you can’t unsee it.
- Use them as a condiment, not a meal. Think of dates like salt or honey. They are there to provide a punch of flavor. Cross-cutting one date into a salad provides enough sweetness for the whole bowl.
- Check for "Sugaring." If your dates have white spots on them, it’s usually just sugar crystallizing on the skin as they dry out. They are still safe to eat, but they will taste even sweeter, so stick strictly to the dates serving size.
- Hydrate. Dates are dried fruit. When you eat concentrated fiber and sugar, you need water to help your body process it. Drink a full glass of water with your snack.
The goal isn't to fear the date. It’s a literal ancient superfood that has sustained civilizations for thousands of years. But we aren't trekking across deserts anymore; we’re sitting in ergonomic chairs. Adjust your intake to match your actual energy needs. Two dates. That’s your golden number. Enjoy them, savor the caramel flavor, and then close the container.
