Which of these tends to result in obesity?
a. maintaining a chronic positive energy balance
b. demonstrating an inability to absorb nutrients in food
c. failing to drink enough water on a daily basis
d. working a sedentary desk job

The correct answer is a. maintaining a chronic positive energy balance

Explanation:

Our food contains calories which provide us energy. Each food type has a different amount of calories. Positive energy balance occurs when we take more calories than we burn.

If we take more calories than we burn for a long time than it will be accumulated in the body in the form of fat and will lead to weight gain and obesity. So maintaining a chronic positive energy balance can lead to obesity.

If we want to reduce the weight than calorie intake should be less than calorie expenditure.
