Foods high in Energy

This list ranks foods by kilocalories per 100 grams, calculated from each food's protein, fat, and carbohydrate content. Because fat supplies roughly twice the energy of protein or carbohydrate gram for gram, the foods at the top are almost entirely concentrated fats and oils rather than the foods most people eat in large amounts day to day — a high ranking here reflects energy density, not a judgment about whether a food belongs in a healthy diet. Energy isn't a nutrient to seek out or avoid the way a vitamin might be; what matters is matching intake to your own needs, which vary by age, sex, body size, and activity level rather than following one fixed number. People with higher energy needs, including growing children and teens, pregnant or breastfeeding individuals, and people with physically demanding jobs or heavy athletic training, will naturally look toward more energy-dense foods to meet those needs without eating unreasonably large volumes. Most people at typical, moderate activity levels get the bulk of their calories spread across a mix of foods rather than from any single entry at the top of this list. Use the ranking to see which foods concentrate the most fuel per gram, then weigh that against your own calorie needs and the rest of what each food provides.
