How Many Calories Should I Eat? Use Our Free Calculator

Determining your daily calorie intake is key to achieving weight loss, maintenance, or gain goals, especially for health-conscious Americans. Our Daily Calorie Intake Calculator uses the Mifflin-St Jeor Equation to estimate your calorie needs based on age, gender, height, weight, activity level, and goals. Tailored for USA users with support for imperial (lbs, inches) and metric (kg, cm) units, this tool helps you plan your diet effectively.

Why Use Our Daily Calorie Intake Calculator?

• Accurate Formula: Uses the Mifflin-St Jeor Equation, a gold standard for estimating calorie needs.
• Customizable Goals: Supports weight loss, maintenance, or gain with tailored calorie recommendations.
• Activity-Based: Accounts for sedentary to very active lifestyles.
• Shareable Results: Share your calorie needs on Twitter, Facebook, or WhatsApp.
• Mobile-Friendly: Works seamlessly on all devices, from smartphones to desktops.

How It Works

The calculator uses the Mifflin-St Jeor Equation to estimate Basal Metabolic Rate (BMR), then adjusts for activity level and goals:

• BMR:
  • Men: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) + 5
  • Women: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age (years) – 161
• Activity Multiplier:
  • Sedentary: BMR × 1.2
  • Light: BMR × 1.375
  • Moderate: BMR × 1.55
  • Active: BMR × 1.725
  • Very Active: BMR × 1.9
• Goals:
  • Weight Loss: –500 kcal/day (1 lb/week loss)
  • Maintain: No adjustment
  • Weight Gain: +500 kcal/day (1 lb/week gain)

Enter your gender, age, height, weight, activity level, and goal. The tool calculates your daily calorie needs and provides tips for healthy eating.

Understanding Daily Calorie Needs

Your daily calorie needs depend on your Basal Metabolic Rate (BMR) and activity level. For example:

• A 30-year-old woman, 5’5” (65 in), 150 lbs, with moderate activity:
  • BMR = 10 × 68 (kg) + 6.25 × 165 (cm) – 5 × 30 – 161 ≈ 1,394 kcal
  • Maintenance (moderate): 1,394 × 1.55 ≈ 2,161 kcal
  • Weight Loss: 2,161 – 500 ≈ 1,661 kcal/day
• A 40-year-old man, 6’0” (72 in), 200 lbs, with active lifestyle:
  • BMR = 10 × 91 (kg) + 6.25 × 183 (cm) – 5 × 40 + 5 ≈ 1,857 kcal
  • Maintenance (active): 1,857 × 1.725 ≈ 3,203 kcal
  • Weight Gain: 3,203 + 500 ≈ 3,703 kcal/day

Tips for Managing Calorie Intake

To achieve your goals:

• Track Food Intake: Use apps or journals to monitor calories.
• Balance Macronutrients: Aim for 40% carbs, 30% protein, 30% fats for weight loss.
• Choose Nutrient-Dense Foods: Opt for vegetables, lean proteins, and whole grains.
• Stay Hydrated: Drink water to support metabolism and avoid overeating.
• Consult a Nutritionist: For personalized diet plans, seek professional advice.
