Final answer:
For those overweight or obese, a loss of 5-10 percent of body weight significantly impacts insulin resistance and overall health risk, critical in reducing the health complications associated with obesity. Option b.
Step-by-step explanation:
For those who are overweight or obese, a loss of 5-10 percent of body weight can have a significant impact on insulin resistance and overall health risk. Obesity leads to an increase in the number of fat cells and the fat mass which induces inflammation and poses a high risk for various diseases, including type 2 diabetes. The link between obesity and type 2 diabetes is notably strong because excess fat affects the body's metabolism and response to insulin, which can result in insulin resistance.
Additionally, losing weight can play a crucial role in improving or reversing complications associated with obesity like heart disease, hypertension, obstructive sleep apnea, certain types of cancers, and more. Therefore, even a moderate loss of 5-10 percent of body weight is an essential step towards reducing the health risks associated with being overweight or obese.
