                                According to Mayo Clinic, roasted chestnuts contain just 70 calories and 0.6 grams of total fat per ounce, making them the clear winner when asking what nut has the lowest fat calorie count. Most nuts are energy-dense due to their high fat content, but the unique nutritional profile of chestnuts sets them apart from more common tree nuts like almonds and walnuts.
