At the time of writing, we’re in the middle of fall, the season of red grapes, beautiful colors – and chestnuts. Chances are, you’re reading this article because you enjoy the smell and taste of roasted chesnuts, but, you’re wondering if they are any good for weight loss. You’re in luck because that’s what we’re covering today—sit tight and read on!


Roasted chestnuts are low in fat and rich in fiber. This nutrient profile makes them ideal for promoting fullness and controlling appetite, along with stabilizing your blood sugar levels. [1] While they are not high in calories, roasted chesnuts can make you gain weight if you overdo it. They’re a healthy addition to a balanced diet, but remember, no single food alone is going to fix your problems – a calorie controlled diet with healthy foods and an active lifestyle with 7-9 hours of quality sleep per night are paramount for long-term weight loss.

A Little Bit About Chestnuts

Chestnuts are a type of nut (duh!) coming from the Castanea tree and shrub species. Flourishing in temperate climates, chestnuts have a surprising diversity of nutrients while being low in fat (this is uncommon with nuts). They do have quite a few carbs which makes them an energy-dense snack. They are also packed with dietary fiber and provide a decent punch of vitamin C, which is, again, a rarity among nuts.

Chestnuts and Weight Loss: The Link?

As you’ve seen in the summary at the beginning, chestnuts have a fairly decent nutritional profile for a weight loss food. Yes, then can aid weight loss as a part of a healthy lifestyle.

First off, chestnuts are rich in dietary fiber, which helps prevent overeating and snacking, two habits that trouble most of us when trying to keep the weight off.

Chesnuts do have some carbs, but they are low in fat, and fat is the most calorie dense macronutrient. Because of this, chestnuts don’t have as many calories as some other nuts, which makes them good for weight loss. As long as you control your portions!

Roasting Chestnuts: Does it Affect their Nutritional Profile?

When chestnuts are roasted, they become softer and develop a delicate, slightly sweet flavor. But does this process alter chestnut’s nutritional profile, and more importantly for this case, does it make them better or worse for weight loss?

The good new is that roasting chestnuts is actually great for making them more digestable. Their fiber content, which is the reason why they make you feel full, stays preserved. Water content does dry up during roasting so you’ll be getting more calories per gram.

Something Else to Consider

Just because they are healthy and nutritious, doesn’t mean that they can’t actually lead to weight gain. This is true if you eat chestnuts in large quantities. They do still pack quite a bit of carbs.

Also, how good chestnuts will be for your weight loss journey depends on where you get them from. Buying from street vendors can lead to weight gain because they may be heavily seasoned with sugar or salt, or even containing additional oils.


What’s not to love about roasted chestnuts? They have unique flavor and unique nutritional profile. They can certainly be part of a weight-conscious diet. The dietary fiber content can help you in maintaining satiety, helping to control overeating, and their relatively low fat and calorie content make them a better snack than any ultraprocessed food.

However, the bottom line is that no single food, including chestnuts, can solely make you lose weight. Shedding pounds for good requires a multi-pronged approach: a balanced diet, healthy sleep, and optimizing your hormones through exercise and supplements.
