Explanation:
To know if a person is overweight we calculate their Body Mass Index which is their weight in kilogrammes divided by the square of their height in meters.
Being overweight is a precursor to obesity. Living a sedentary lifestyle while being overweight is bad for your health. It increases the levels of bad fat in the body and this can lead to insulin resistance by the body cells causing sugar to build up in the blood and ultimately leading to diabetes disease.
Low level of physical activity while overweight is also bad for your joints as it puts too much weight on them and might cause arthritis.
Increased levels of unhealthy fats in the body can cause them to block the small vessels circulating blood and this can lead to stroke and hypertension.
To prevent these complications, people should make efforts to control their weight by applying various lifestyle changes. Such changes as regular exercises, brisk walking , using the stairs, cutting down on high calorie foods and eating healthy helps bring weight to normal physiological levels.
