We'll explore its nutrition, how it aligns with keto guidelines, and even offer up some alternatives. So, if you're ready to unravel the mystery of guava's keto-friendliness, keep reading!


  • Guava is not a keto-friendly fruit due to its high net carb content.
  • Eating Guava could risk pushing you out of the much-needed state of ketosis in a ketogenic diet.
  • The best substitute for guava would be berries, such as strawberries or raspberries, due to their lower carbohydrate content.

Is Guava Keto-Friendly?

Let's talk about whether guava fits into a keto diet. Here's the deal: while guava is packed with nutrients and tastes amazing, it's not the best choice for keto.

Here's why: when you look at the numbers, 100 grams of guava has about 8.92 grams of net carbs. Now, net carbs are the ones your body can actually use for energy, once you subtract the fiber.

So, why does this matter for keto? Well, keto is all about getting your body into a state called 'ketosis,' where it burns fat for fuel instead of carbs. To do that, most people on keto try to keep their daily carb intake pretty low, usually between 20 to 50 grams.

With almost 9 grams of net carbs in just 100 grams of guava, that's a big chunk of your daily carb limit, especially if you're aiming for the lower end. So, while guava might be delicious, it can be tough to fit into a strict keto diet.

Can You Have Guava On a Strict Keto Diet?

While Guava is packed with nutrients, it's not the best choice for a strict keto diet. This tropical fruit contains a significant amount of net carbs, with approximately 8.92 grams per 100-gram serving. Since the goal of a strict keto diet is to keep carb intake low to promote ketosis, consuming Guava could quickly use up a large portion of your daily carb allowance, especially if you're aiming for the lower end of the recommended range, typically between 20 to 50 grams per day.

Guava on a low-carb diet?

Guava may still be enjoyed in moderation on a low-carb diet. While it's higher in carbs compared to other fruits, incorporating small portions of guava into your meal plan can still be feasible, especially if you're following a less restrictive low-carb approach that allows for slightly higher carb intake. However, it's essential to track your carb intake from guava and other sources to ensure it fits within your overall daily carb limit.

Carbs in Guava

Alright, let's break down the carb situation with guava and how it fits into the keto diet. So, here's the deal: the amount of carbs in guava, especially its net carbs, is what matters most when it comes to keto.

First off, let's talk about net carbs. These are the carbs your body actually uses for energy after subtracting the fiber. Fiber doesn't affect your blood sugar like other carbs do, so we can subtract it.

Now, back to guava. For every 100 grams of guava, you're looking at around 14.32 grams of total carbs, with a good chunk of that being fiber - about 5.4 grams. So, the net carbs, which are the ones that count for keto, come out to about 8.92 grams.

But what does this mean practically? Well, if you're sticking to a 20-gram daily carb limit, which is pretty common for strict keto, just 100 grams of guava would take up almost half of your allowance. And if you're thinking of having a small cup of sliced guava, which is about 165 grams, you'd already be over your daily limit, with around 14.7 grams of net carbs.

Cast Iron Keto's Editorial and Research Standards

Certain rare or exotic food items may not have nutritional profiles in the FoodData Central database. If an exact match is not found in the FoodData Central database, then, the Cast Iron Keto team utilizes a three-prong approach to provide readers with the closest relevant nutritional data, where possible.

First, in the event that nutritional profiles for a rare or exotic food item is not available in the FoodData Central database, we investigate alternative names for that particular food item and use that data, when possible. Second, in cases where no alternate names exist, Cast Iron Keto will use nutritional data for a close relative or similar food item. Finally, if no close relatives or similar items exist, we refrain from publishing nutrient data tables.

When making dietary or health decisions based on FoodData Central's data, we suggest readers consult with a nutritionist or other health experts, particularly if the food in question has a significant role in your diet or if you are using the food item to treat any health disorder(s).

Furthermore, it is important to note that even if a close relative or similar item is used to approximate the nutritional data, different food items can have varying levels of nutrients due to factors such as soil quality, farming practices, and regional differences.
