Fat is a type of body tissue that stores energy in the form of triglycerides. It is found throughout the body, including under the skin, around organs, and in the bone marrow. Fat plays an important role in many bodily functions, including storing energy, protecting organs, regulating body temperature, and producing hormones. While fat is an essential part of a healthy body, too much fat can lead to a number of health problems, including weight gain, heart disease, liver disease, kidney disease, and other health problems. The amount of fat you should burn depends on your individual goals. A healthy body fat percentage for women is between 21% and 33%, and for men, it is between 10% and 22% 123.
