The **Dietary Reference Intake (DRI)** helps individuals estimate their daily **energy and nutrient needs** based on various personal factors such as **age, gender, weight, height, and activity level**.
It is used to plan **healthy diets** that support **energy balance, muscle maintenance, and overall well-being**.
🌱 What Does DRI Include?
Energy Requirement: The estimated daily calorie intake needed to maintain body functions and activity levels.
Macronutrients: The recommended intake of **proteins, carbohydrates, and fats** to support body functions.
Metabolism Factor: Energy needs vary based on **individual metabolic rate and lifestyle**.
🔥 How Energy Needs Are Estimated
The total energy required depends on two main factors:
Resting Energy Use: Energy required to sustain basic body functions, such as breathing and digestion.
Activity Energy Use: Additional calories required for movement, exercise, and daily tasks.
By combining these, we can estimate your total **daily energy expenditure (TDEE)**, which helps determine how much food energy you need daily.
🍽️ Macronutrient Breakdown
Your daily energy intake is divided among three key macronutrients:
Proteins: Essential for **muscle repair, immune function, and hormone production**.
Carbohydrates: The primary source of **quick energy** for the body.
Fats: Support **cell function, hormone production, and long-term energy storage**.
🏃♂️ Impact of Activity Level
Your energy needs change based on your daily activity level. **More active individuals** require **higher calorie intake**, while **sedentary individuals** need fewer calories to maintain balance.
