Welcome to the All in one Health Tool. If you're asking, "how healthy am I" then this calculator will help you out. After entering you weight, height, age and exercise level, the calculator will give you information such as your daily calorie needs, BMI and ideal weight. If it detects you're over or underweight, it'll prescribe a daily calorie intake and tell you how long it'll take for you to reach your target. For more detailed information that you can use to get in shape and start eating healthy, get a free diet and workout routine.
