Is Jackfruit Keto? Sugar Alert (10 Keto Fruits & Meat Alternatives)

Keto (Low Carb) | Written by Nathan Petitpas | Updated on 8 April 2023

A pregnant woman, wearing a white dress with brown patterns and a blue shawl is holding and starring at a large jackfruit hanging from a tree beside her and wondering is jackfruit keto?

Jackfruit has become an increasingly popular health food, but low carb dieters may find themselves wondering is jackfruit keto and can it be enjoyed while remaining in ketosis?9

As most are aware, the keto diet allows for 30-50 grams of carbs per day, and while anything can technically be eaten on keto if daily carb limits are adhered to, dieters should be alerted by the amount of natural sugar in this juicy fruit.1

Dieters can learn more about how many carbs are in jack fruit, how to make small quantities into their diet, its health benefits and 10 keto fruit alternatives that include some others that make great meat substitutes. 

Is Jackfruit Low Carb? (Total and Net Carbs in Jackfruit)

Much like the avocado, spinach, and turmeric, jackfruit has become well known in the health world as the new “it” superfood, offering a number of healthy benefits. But keto readers must know the answer to, “is jackfruit keto and how many carbs are in jackfruit?” before they can start integrating this ingredient into their diet.  

When it comes to tracking carbohydrates, it’s best practice to check out both the total and net carbs in a food. The total carbs simply means all the carbohydrates a particular food contains. 

This will include fiber, sugar, and generalized carbohydrates. The net carbs, on the other hand, are calculated a little differently; they will be the total carbohydrates minus the amount of non-digestible carbohydrates aka fiber. 

Jackfruit, per every 1 cup serving size, has roughly 38 grams of carbohydrates and 2.5 grams of dietary fiber.2 So this means that the total amount of carbs is 38 grams, and the net carbs is 35.5 grams.

Furthermore, the amount of calories in jackfruit is 143 grams per one cup serving size, making it fairly low calorie for those wanting to lose weight. 

When it comes down to it, jackfruit is similar to other carb dense foods like potatoes or bread. But even though jack fruit is high in carbs, it may still be feasible to enjoy when using carb counting strategies or when eating very, very small quantities. 

How Much Natural Sugar Is in Jackfruit? 

Perhaps even more important than the carb content, is the amount of sugar! Jackfruit has roughly 31.5 grams of sugar per one cup serving size, which is a considerable amount for just one sitting.

Those with sugar sensitivities, such as people with diabetes or prediabetes, should be mindful of their own blood sugar levels before enjoying this food. Make sure to check out a food’s glycemic index, a scale that estimates blood sugar responses to various foods, to help decide if it fits into a keto diet plan. 

The good news for those on the jackfruit diet, is that the sugar in jackfruit is not the worst kind of sugar. It’s actually made of fructose, which does not cause a significant insulin spike after eating. 

Foods that are high in fructose rather than the unhealthy, ultra-processed, and refined glucose tend to be a much healthier alternative for dieters who are craving something sweet. 

Is Jackfruit Keto Approved? Can You Eat Jackfruit on a Keto Diet? 

Now for the question keto dieters really want to know: Is jackfruit keto? The answer is a little tricky.  

Even though one serving of jackfruit technically fits into the 50 grams of carbohydrates allowed per day, that doesn’t mean the fruit is keto approved. In fact, one serving would take up 76% of a keto dieter’s carb allowance per day!

Eating this many carbohydrates in one sitting will make meal planning pretty difficult, and can cause some dieters to accidentally break their diet plan.

In addition to looking at the carbohydrate content, it’s also important to consider a food’s glycemic index, which rates the body’s blood sugar response to specific foods. Ketogenic dieters should aim to eat carbs that have what’s referred to as a low glycemic index number in order to help stay in ketosis, which includes foods rated at a 55 or less on the GI scale.3 

Jackfruit tends to fall into the moderate glycemic index, making it best to be avoided if possible.  

As a final verdict, the answer is no, jackfruit is not keto approved, and should be avoided on a low carb diet plan since it contains too many natural sugars and the carbs that come along with that.

But don’t worry, there are still ways to incorporate this superfood in a healthy, and keto-friendly way as long as the right strategies are being used. 

Plus, there’s other alternatives that we’ll get to and you may enjoy them even more!

How To Make Jackfruit Fit Into Keto Diet Plan

Still wanting to enjoy jackfruit on a keto diet? Don’t worry, because there are many different strategies that a dieter can use to make this carb heavy food work with a keto diet plan. 

First off, portion control is key and must be practiced. A standard serving size for jackfruit is one cup with 38 grams of carbs, but a keto-friendly portion of a half cup will only have 16 grams of total carbs. 

This smaller serving size is much more feasible to fit into a diet plan, and keep keto dieters on the right track. It’s pretty much a healthy hack to have a cake and eat it too. 

Using a keto recipe is also a tool for success, especially when it comes to incorporating high in carb foods like jackfruit. Look for recipes that combine jackfruit with keto friendly foods that are high in protein and fat, while low in carbohydrates. 

High protein foods have been found to help people feel more full for longer periods of time, helping to aid in weight loss management.4 So dieters should keep in mind that combining jackfruit with a high protein source will help keep them to feel more full after a meal. 

Finally, keto readers are encouraged to make sure they are making correct measurements to make sure they are adhering to the correct serving sizes and corresponding carbohydrate content. This helps to ensure the correct amount of carbohydrates are being consumed in order to stay in ketosis. 

Is Jackfruit Healthy?

Jackfruit has become a hot, new superfood in the health and fitness space for a reason. It has a number of nutritional benefits that make this fruit extremely healthy to eat, and eating healthy foods is one of the 3 steps to lose weight
