highcalorie

High-calorie, or high-energy, foods are those that deliver a large number of kilocalories per unit of weight or volume. In nutrition, calories are commonly expressed as kilocalories (kcal). Energy density measures how many calories a food provides per gram; high-energy-density foods offer more calories per gram than low-energy-density foods.

In nutrition, high-calorie intake is relevant for weight gain under conditions of undernutrition, intense physical training, or certain medical needs. Conversely, excessive high-calorie intake can contribute to overweight and obesity. The goal is to align calories with energy expenditure while maintaining nutrient adequacy.

Common sources include fats and oils, nuts and seeds, full-fat dairy products, fatty fish and meats, avocados, dried fruits, granola, and many processed snacks. Beverages such as milkshakes and smoothies with added fats or sugars can also be high in calories. The majority of calories in these foods typically come from fats (about 9 kcal per gram), while carbohydrates and proteins provide about 4 kcal per gram.

Dietary planning around high-calorie foods often emphasizes nutrient density to supply vitamins, minerals, and fiber alongside energy. Attention to portion size and balance helps minimize the risk of nutrient gaps or excessive fat intake. Individuals with specific health conditions should seek professional guidance for tailored recommendations.
