Dietary Reference Intake Calculator

Eating right keeps you healthy, but how much do you really need? The Dietary Reference Intake (DRI) Calculator makes it simple. It helps you figure out how many calories, proteins, and vitamins your body needs daily. Whether you're maintaining weight, losing fat, or building muscle, this tool gives you clear answers.

What is Dietary Reference Intake (DRI)?

DRI is a set of nutrition guidelines designed to help people meet their daily nutrient needs. It includes:

• Recommended Dietary Allowance (RDA): The ideal daily intake for most people.
• Adequate Intake (AI): A safe estimate when RDA isn't available.
• Tolerable Upper Intake Level (UL): The maximum daily amount before it may harm you.
• Estimated Average Requirement (EAR): The intake level that meets the needs of half the population.

These values depend on age, gender, weight, and activity level.

How to Calculate Your DRI?

Your daily calorie needs depend on how active you are. Here’s the formula:

Calories = Basal Metabolic Rate (BMR) × Activity Factor

Once you know your calories, you can split them into carbs, proteins, and fats using these guidelines:

Example: If your daily calorie goal is 2000 kcal, your breakdown would be:

• Carbs: 225-325g
• Proteins: 50-175g
• Fats: 44-78g
