Oatmeal calories & macros
71 calories per 100 g · 166 calories per 1 cup cooked (234 g). Oatmeal (cooked with water).
Cooked oatmeal is a famously filling breakfast: a cup made with water is about 166 calories and brings soluble fiber (beta-glucan) that slows digestion and steadies blood sugar. Because it cooks up to a large, warm volume, it satisfies far more than its calorie count suggests. Watch the toppings — brown sugar, honey, and dried fruit are where oatmeal's calories usually climb.
