When evaluating which grain is lowest in calories, it's important to consider grains in their cooked form, as cooking adds water and significantly changes the calorie density per serving. Bulgur, a form of cracked wheat, consistently ranks among the lowest, along with other nutrient-dense options like buckwheat and pearled barley. Choosing whole, unrefined grains over processed ones is always recommended for maximum nutritional value and satiety.
Low-Calorie Grains for a Healthy Diet
Many whole grains are excellent for weight management because their high fiber content helps you feel full longer on fewer calories. Here are some of the top contenders for the lowest-calorie spot:
- Bulgur: Made from cracked, parboiled wheat, bulgur is one of the quickest and lowest-calorie options. One cup of cooked bulgur contains only about 151 calories. Its high fiber content aids digestion and promotes satiety, making it an excellent base for salads like tabbouleh or as a substitute for rice.
- Buckwheat: This pseudo-cereal is gluten-free and has a rich, earthy flavor. A cooked cup of buckwheat groats contains around 155 calories and is a great source of protein and fiber. It can be used in porridges, pancakes, or as a side dish.
- Pearled Barley: While hulled barley is a whole grain, pearled barley has the bran removed. Though slightly less fiber-dense than its hulled counterpart, it is still a low-calorie option, with one cooked cup containing about 193 calories. It adds a satisfying, chewy texture to soups and stews.
- Oats: Especially steel-cut or old-fashioned oats, this supergrain is high in fiber and protein, which helps curb appetite. A half-cup serving of dry oats has about 154 calories, which makes for a calorie-friendly and filling breakfast once cooked.
- Millet: A gluten-free ancient grain, millet offers good levels of minerals and has about 207 calories per cooked cup. It can be used as a couscous substitute or as a light, crunchy addition to dishes.
- Wild Rice: Technically a grass, wild rice is lower in carbohydrates and calories compared to brown rice, with a cooked cup containing about 166 calories. It has a robust, nutty flavor and is rich in B vitamins and minerals.

How to Incorporate Low-Calorie Grains into Your Diet
Making low-calorie grains a regular part of your meals can help with weight management and boost your overall nutrient intake. Experiment with different cooking methods and recipes to find what works best for you.
Simple Ways to Enjoy Your Grains
- Morning Porridge: Replace your standard oatmeal with buckwheat or teff for a hot, hearty, and fiber-rich breakfast. Add berries and a sprinkle of nuts for extra nutrients without excess calories.
- Salad Base: Use cold bulgur or quinoa instead of leafy greens to create a satisfying and filling salad. Toss with chopped vegetables, herbs, and a light vinaigrette for a refreshing meal.
- Stir-fry Substitute: Swap out white rice for cooked wild rice or millet in stir-fry dishes. These grains absorb flavors well and add a distinct texture.
- Hearty Soups and Stews: Add pearled barley or farro to thicken soups and stews. They maintain their chewy texture and provide a satisfying element to any winter dish.
- Veggie Burgers and Meatloaf: Mix cooked bulgur or buckwheat into ground meat or plant-based proteins to add bulk, fiber, and nutrients to your patties.
By focusing on whole, minimally processed versions, you can maximize the health benefits of low-calorie grains. Always consider portion sizes, as excessive amounts will increase overall calorie intake regardless of the grain type. Pair these grains with lean proteins and plenty of vegetables to create balanced and satiating meals. For personalized dietary advice, it is always recommended to consult a nutritionist or medical professional.
Conclusion
For those seeking the lowest-calorie options, bulgur wheat is a standout choice due to its low cooked calorie count and high fiber content, which significantly promotes satiety. Other strong contenders include buckwheat and wild rice. Beyond just the calorie count, the key to successful weight management with grains lies in choosing whole, minimally processed varieties. These provide essential fiber, protein, and nutrients that aid digestion, control appetite, and offer sustained energy, making them a cornerstone of a healthy diet. By incorporating a variety of these wholesome grains and being mindful of portion sizes, you can effectively manage your caloric intake while enjoying delicious and nutritious meals.
