Online Calorie Calculator Free
An online calorie calculator free is a tool that estimates the number of calories a person needs to consume in order to maintain, gain, or lose weight. It takes into account factors such as age, gender, weight, height, activity level, and goals.
This online calorie calculator free provides only an estimate, as individual calorie needs can vary. It’s always a good idea to consult with a healthcare professional or registered dietitian for personalized advice.
Here’s a basic formula known as the Harris-Benedict equation, which is commonly used to estimate calorie needs:
For men: BMR = 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) – (5.677 × age in years)
For women: BMR = 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) – (4.330 × age in years)
Once you have your Basal Metabolic Rate (BMR), you can multiply it by an activity factor to estimate your total daily calorie needs. Here are the activity factors:
Sedentary (little to no exercise): BMR × 1.2
Lightly active (light exercise/sports 1-3 days per week): BMR × 1.375
Moderately active (moderate exercise/sports 3-5 days per week): BMR × 1.55
Very active (hard exercise/sports 6-7 days per week): BMR × 1.725
Extra active (very hard exercise/sports and a physical job): BMR × 1.9
These calculations estimate calorie needs for weight maintenance. To lose weight, you generally need to create a calorie deficit by consuming fewer calories than your estimated needs, and to gain weight, you need to consume more calories than your estimated needs.
This is just a rough estimate, and other factors such as genetics, metabolism, and specific medical conditions can also affect your calorie needs. It’s always a good idea to consult a healthcare professional or registered dietitian for personalized advice.
