Top 9 Lowest To Highest Calorie Nuts

The tables below show the number of calories in each kind of nut in order of lowest to highest, including nutritional information so you can compare each type based on your dietary needs.

Figures are based on official USDA data, and you can find source links at the bottom of this page.

A serving is based on 1oz (28.35g), which is equal to a handful of nuts.

1 – Cashew Nuts

You might be surprised to learn that the nut with the least amount of calories is cashew nuts which contain 157 calories per serving.

You might have seen conflicting information saying cashews aren’t the healthiest nut – which is true. Just because they have the least calories doesn’t make them the most beneficial option.

Cashews are lower in calories than other nuts because they’re lower in natural fat, but they’re also the highest in carbs on this list and are low in fiber.

So if you’re on a low-calorie diet, cashews are a good snack option; however, if you’re on a low-carb diet, they’re probably not the best nut for you.

Summary

So, we’ve learned that cashew nuts are the lowest in calories while macadamia nuts are the highest – however, we’ve also found out that lower calorie doesn’t always mean healthiest.
