Fat has a bad reputation for leading people to be overweight and obese. However, people must also know that not all fat is bad. In fact, breaking down and storing energy (calories) in the form of fat is actually a healthy practice. It’s just one of the many ways our body uses food to work, heal, and grow which is why having a well- balanced diet is always recommended. The energy that is stored from fat helps you get through a strenuous job or workout. It plays an integral role in brain development, and in preventing swelling (inflammation) and blood clots. Fat helps you get healthy hair and skin as well. You can determine whether you are underweight or not by using a Body Mass Index (BMI) calculator, an online tool that considers your weight, height, age, and gender to calculate a value and if your BMI is less than 18.5, you are underweight. Even your healthcare provider can help determine if you’re underweight based on your height, weight, what you eat, and your activity level.
