Answer 1

The food-scarce environment of our ancestors has led to humans' propensity to gorge when food is available and crave high-caloric foods. This propensity can contribute to an epidemic of obesity in a food-abundant society. Genetics, changes in diet and activity levels, and socioeconomic and environmental factors also play a role in obesity.

Step-by-step explanation:

The propensity to gorge when food is available and to crave high-caloric foods is a trait that can be attributed to the food-scarce environment of our ancestors. In the past, when food was less accessible and physical activity levels were higher, individuals needed to consume as much energy as possible to survive periods of famine. However, in the modern world where food is plentiful and activity levels have declined, this trait can lead to an epidemic of obesity.

This can be seen in how our bodies store excess fat. People who store most of their excess fat in the abdomen have central obesity, which puts them at a greater risk of adverse health consequences of obesity. Additionally, genetics play a role in obesity, with certain genes controlling appetite and metabolism predisposing individuals to develop obesity when sufficient food energy is present.

Furthermore, changes in diet and activity levels over time have contributed to the rise of obesity rates. Diets have increased in Calories, mainly from excess carbohydrates, and activity levels have declined due to changes in work and technology. These factors, along with socioeconomic status and the physical environment, can also influence someone's weight. For example, individuals living in neighborhoods with limited food options or unsafe conditions may have limited access to healthy food and opportunities for physical activity, leading them to rely on high-calorie fast food as their primary source of nutrition.

In conclusion, the food-scarce environment of our ancestors has influenced humans' propensity to gorge when food is available and crave high-caloric foods. However, in today's food-abundant society, this trait can contribute to the epidemic of obesity. Genetic factors, changes in diet and activity levels, and socioeconomic and environmental factors all play a role in the development of obesity.
