## Calorie Calculator (US Units)

Calorie Calculator (US Units) estimates the number of calorie you need daily to manage your fitness and weight goals (maintain, gain or lose weight) based on your physical activity level; understand that helps to plan your long-term nutrition intake and exercise program.

### What Is Calorie?

A calorie is a unit of energy. The term "calorie" is scientifically defined as the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius. 

However, the calorie we talk about is the amount of energy in what we eat and drink, the calories in food provide energy in the form of heat so that our bodies can function even at rest to maintain basic body functions like breathing and blood circulation. 

### What Is My Ideal Daily Calorie Intake?

An ideal daily intake of calories varies depending on age, gender and levels of physical activity. A healthy amount of calories for adult women ranges from 1,800 to 2,400 calories per day and for men it's 2,000 to 3,200 calories per day. 

Choose the activity level that best describes your daily routine (yoga, aerobic, walking, running, cycling, etc.) to estimate your calorie intake.

- No exercise (or very little)
- Light exercise (1-3 times/week with 30-60 minutes/session)
- Moderate exercise (4-5 times/week with 30-60 minutes/session)
- Active exercise (daily exercise with 30-60 minutes/session or intense exercise  3-4 times/week with 20-40 minutes/session)
- Very active exercise (intense exercise 6-7 times/week with 20-40 minutes/session)
- Extra active exercise (intense exercise 2 times per day or professional athlete; 40+ minutes/session)
