There are many hypotheses about why obesity and diabetes are increasing in modern societies, many of them based on evolutionary mismatch. Describe three of these hypotheses.
On Jul 26, 2024
1. The Thrifty Gene Hypothesis: This hypothesis suggests that our bodies have evolved to efficiently store and conserve energy during times of scarcity. However, in modern societies where food is abundant, this genetic predisposition to store energy leads to obesity and diabetes.
2. The Sedentary Lifestyle Hypothesis: This hypothesis proposes that our modern sedentary lifestyle, characterized by a lack of physical activity and prolonged periods of sitting, is a mismatch with our evolutionary history of being active hunter-gatherers. This lack of physical activity contributes to the rise in obesity and diabetes.
3. The Western Diet Hypothesis: This hypothesis suggests that the modern Western diet, which is high in processed foods, sugar, and unhealthy fats, is a major contributor to the increase in obesity and diabetes. Our bodies may not have evolved to efficiently process and metabolize these types of foods, leading to negative health outcomes.

About 12 to 24 hours after the last meal, a person's blood sugar level normally varies from 60 to 90 mg per 100 ml of blood, although it may rise to 130 mg per 100 ml after meals high in carbohydrates. Yet, the blood sugar level is maintained within a fairly narrow range, despite uneven intake of sugar. This is possible due to the process of ____.
A) adaptation
B) homeostasis
C) inheritance
D) metabolism
E) development
