Q. 27 - Biology

Question

Discuss why obesity is a growing epidemic.

Step-by-Step Solution

Answer

Fast food's high-calorie density and trans-fat content are just two of the causes of the obesity pandemic. 

Step 1: Introduction

Globally, there has been a rise in the consumption of calorie-dense foods that are rich in fat and sugar as well as an increase in physical inactivity as a result of the changing modes of transportation, rising urbanization, and the lethargic nature of many occupations.

Step 2: The explanation for the answer

Fast food's high-calorie density and trans-fat content are just two of the causes of the obesity pandemic. The portion sizes of many foods have increased during the past 30 years, which has boosted energy intake. People don't exercise much, yet in order to maintain their health, they need to exercise for at least an hour each day.  Thus, it has become an epidemic.
