The free BMI Calculator helps you quickly calculate your Body Mass Index and find out if your weight falls within the healthy range. It's a simple, science-based tool for tracking fitness, weight loss, or weight maintenance goals. Perfect for beginners and advanced users alike.
What is BMI and what does it mean?
BMI (Body Mass Index) is a simple number that comes from the ratio of your weight to your height. The formula is: weight (kg) ÷ (height in meters²). This value helps estimate whether someone falls into the underweight, normal weight, overweight, or obese category. While BMI doesn't account for muscle mass or body fat percentage, it's still a useful guideline for assessing overall health, especially for people looking to make lifestyle changes. With the GetFIT App, anyone can work toward getting their BMI into the healthy range - with personalized calorie tracking, nutritious and delicious recipes, plus goal-oriented workout plans that help you get in shape in a sustainable way.
What counts as a healthy Body Mass Index?
A healthy Body Mass Index (BMI) falls between 18.5 and 24.9. This range generally indicates that your weight is proportional to your height, and you have a lower risk of chronic diseases like heart disease, diabetes, or high blood pressure. It's important to know, though, that BMI doesn't account for body fat percentage or muscle mass. That's why it's worth paying attention not just to BMI, but also to body composition, diet, and exercise. The GetFIT App gives you all the tools to get into the healthy BMI range: smart calorie tracking, amazing healthy recipes, workout plans, and lifestyle programs help you not just lose weight, but maintain your new lifestyle for the long haul.
What should I do to lower my BMI?
To lower your Body Mass Index (BMI), you need to lose weight, which is most easily achieved by creating a calorie deficit - meaning you need to burn more energy than you take in. This requires the right diet, adequate protein intake, and regular exercise, including both strength training and cardio. Watch out for hidden calories, eat a balanced diet, and be patient - lasting change takes time. This is where the GetFIT App helps: you get not just precise calorie tracking, but amazing diet-friendly recipes, personalized workout plans, and complete lifestyle programs. This way, anyone can lower their BMI into the healthy range while shaping their body and building new habits.
How much does BMI matter?
BMI can be a useful guideline number, but it doesn't give you the full picture of your health. It doesn't distinguish between muscle and fat, so for example, a muscular athlete might appear "overweight" based on BMI alone, even though they're in excellent health. The same goes the other way: a normal BMI doesn't rule out high body fat percentage. What really matters is body composition - especially the ratio of body fat percentage to muscle mass. These give a much more accurate picture of how fit, healthy, and aesthetically pleasing you are. The GetFIT App helps you focus not just on a number, but on actually getting in shape: with calorie tracking, amazing fitness recipes, workout plans, and lifestyle programs that support you in reducing your body fat percentage and building a body you feel great in.
How can I lose weight easily?
The key to simple and effective weight loss is a calorie deficit - meaning you take in less energy than you burn. You don't have to starve yourself - you just need to choose your foods wisely, exercise regularly, and listen to your body's signals. The biggest help is bringing structure to your eating, movement, and daily routine. The GetFIT App is incredibly helpful with this: it supports you throughout your journey with precise calorie tracking, delicious yet diet-friendly recipes, and personalized workout plans. The best part is that it's not just for people who want to lose weight - it's for anyone who wants to live a healthier, fitter life. Because you don't have to be overweight to make a change. Being healthy isn't a destination, it's a lifestyle. And the GetFIT App gives you all the tools you need for that!

What is a calorie deficit and what does it mean?
A calorie deficit means you're taking in fewer calories than your body uses throughout the day. When this happens, your body is forced to tap into its reserves - meaning it starts burning fat, and weight loss begins. This is the most important basic principle if fat loss is your goal. Many people mess this up by not accurately counting their calorie intake, underestimating portion sizes, or forgetting to log "just one bite." This way they easily slip out of a real deficit. The GetFIT App is a huge help with this: it puts a precise calorie tracker in your hands, so you can easily monitor your daily intake and make sure you're actually staying in a calorie deficit - because that's the only way you'll see results. If weight loss is your goal, this is one of your most important tools!
