+It is widely used as a general indicator of whether a person has a healthy body weight for their height. Specifically, the value obtained from the calculation of BMI is used to categorize whether a person is underweight, normal weight, overweight, or obese depending on what range the value falls between. These ranges of BMI vary based on factors such as region and age, and are sometimes further divided into subcategories such as severely underweight or very severely obese. Being overweight or underweight can have significant health effects, so while BMI is an imperfect measure of healthy body weight, it is a useful indicator of

+# BMI and BMR Calculator
+
+This Streamlit application calculates BMI and BMR for adults. Users input their height, weight, age, and gender to get their BMI, BMR, and a short analysis of their weight category, including insights on whether they are underweight, normal weight, overweight, or obese.
+
+
+## Run the application
+
+Download the repo
+
+```bash
+  git clone https://github.com/gitarshmah/Awesome-Python-Scripts.git
+```
+
+Go to the project directory
+
+```bash
+  cd BMI_and_BMR_Calculator/
+```
+
+Install Streamlit 
+
+```bash
+   pip install streamlit
+```
+
+Run the app
+
+```bash
+  streamlit run 1_Home.py
+```
