The correct answer is option D. The lack of excercise came before the obesity

Obesity and exercise have a negative association. About 95% of obesity cases are directly related to poor lifestyle and excessive food intake.

To achieve an adequate weight you must have healthy habits such as eating a balanced diet and exercise to avoid sedentary lifestyle.

The lack of exercise came before obesity due to modern sedentary lifestyle, which means that people spend a lot of their time sitting without resorting to any physical activity. Working days also play a determining factor in sedentary lifestyles.

The comforts that we have at hand, such as computers, elevators, remote controls and transportation, cause that the energy consumption is lower, causing weight gain.

Simple activities, such as going for a walk, dancing, running, riding a bicycle, favor a healthy life.
