Our body weight is determined by the amount of energy that we take in as food and the amount of energy we expend in the activities of our day. Energy is measured in calories. If your weight remains constant, you are probably taking in the same amount of calories that you burn each day. If you’re slowly gaining weight over time, it is likely that your caloric intake is greater than the number of calories you burn through your daily activities.
Obesity is defined as having an excessive amount of body fat. Obesity is more than just a cosmetic concern, though. It increases your risk of diseases and health problems such as heart disease, diabetes and high blood pressure. You should always consider obesity treatment if you are overweight.
