Multiple Choice

Of the following, the greatest influence on the growth of weight problems in America is:

Genetic changes in the population over the past few decades

A significant decrease in the average metabolic rate

Widespread use of prescription medications

Increased availability of high-calorie, processed foods

Previous problemNext problem

Verified step by step guidance

Understand that the question asks for the greatest influence on the growth of weight problems in America, focusing on environmental and behavioral factors rather than biological changes.

Recognize that genetic changes in a population occur over many generations and are unlikely to explain rapid increases in weight problems over just a few decades.

Consider metabolic rate changes; while metabolism can vary, a significant population-wide decrease in average metabolic rate is not well-supported as the main cause of increased weight problems.

Evaluate the impact of prescription medications; although some medications can affect weight, their widespread use alone does not account for the large-scale rise in weight issues.

Focus on the increased availability of high-calorie, processed foods, which has changed dietary patterns and energy intake, making it the most influential factor in the growth of weight problems.
