Calories are units of energy that our bodies derive from food and beverages to fuel daily activities, growth, and bodily functions. Here’s a basic overview:
What Are Calories?
A calorie is a measure of energy, specifically the amount needed to raise the temperature of 1 gram of water by 1 degree Celsius.
In nutrition, we use “kilocalories” (kcal), often just called calories, to describe the energy in food.
Daily Calorie Needs
Average Requirements: Adults typically need 2,000–2,500 kcal per day, but this varies based on factors like age, sex, weight, height, and activity level.
– Men: Often 2,500–3,000 kcal for active individuals.
– Women: Often 2,000–2,200 kcal.
Children and Teens: Needs range from 1,000–3,000 kcal, depending on age and growth stage.
Factors Influencing Needs:
– Sedentary lifestyle: Lower calorie intake.
– Physical activity: Higher needs for athletes or manual laborers.
– Age: Needs decrease with age due to slower metabolism.
Sources of Calories
Carbohydrates: 4 kcal per gram; main sources include grains, fruits, and vegetables.
Proteins: 4 kcal per gram; found in meat, dairy, beans, and nuts.
Fats: 9 kcal per gram; from oils, avocados, nuts, and fatty meats.
Alcohol: 7 kcal per gram, though it’s not a nutrient.
Calorie Balance and Health
Maintenance: Consume calories equal to what you burn to maintain weight.
Weight Loss: Create a deficit by consuming 500–1,000 fewer kcal than burned daily.
Weight Gain: Eat 250–500 more kcal than burned.
Health Tips: Focus on nutrient-dense foods (e.g., vegetables, lean proteins) rather than empty calories (e.g., sugary drinks). Track intake using apps or journals for better awareness.
