Final answer:
Obesity leads to increased health risks such as cardiovascular disease, type 2 diabetes, and cancer due to the stress of excess fat on the body and the metabolic changes it causes. Diet plays a critical role in obesity, and addressing dietary habits is key to combating this public health issue.
Step-by-step explanation:
Impact of Obesity on Health
Obesity is a significant health risk that contributes to various health alterations, including heart disease (HD), hypertension, and cancer. It increases the risk of serious conditions such as cardiovascular disease, stroke, Type 2 diabetes, and liver disease. One of the fundamental ways that obesity influences health is by increasing fat mass and the number of fat cells, which can lead to a multitude of problems.
Excess body fat places substantial stress on the body, leading to diseases like osteoarthritis and obstructive sleep apnea. Moreover, the increase in fat cells can cause enhanced inflammation and a higher risk of blood clots, altering the body's metabolism. Consequently, this affects the body's response to insulin, increasing the risk of insulin resistance and type 2 diabetes, with a majority of cases linked to obesity.
Ongoing efforts aim to address the public health concern by understanding the role of dietary habits in contributing to obesity. High-calorie diets rich in fats and sugars without adequate physical activity can lead to weight gain, increasing the likelihood of becoming obese, which in return is connected with various health challenges.
