Case Study 9-2: Lifestyle Changes for Weight Loss
Sally is a 43-year-old mother of two who has gained 50 pounds over the past five years. She is 64 inches
tall and weighs 180 pounds with a BMI of 30.8. Her waist circumference is 37 inches. She acknowledges
that she is not as physically active as she would like to be. She also notes how recent stresses in her life
have affected her sleep and seem to have triggered her appetite for sweets. Sally’s father recently died
from complications of type 2 diabetes and her mother and sisters are overweight. Sally says she is very
motivated to “not get diabetes” and is disturbed that her recent physical exam revealed mildly elevated
blood pressure, glucose, and cholesterol levels.

1.How does Sally’s family history influence her weight and risk for diabetes? What lifestyle
choices may influence her genetic predisposition to be overweight?
Sally's family history plays a significant role in influencing her weight and risk for diabetes. Her father's
complications from type 2 diabetes indicate a genetic predisposition to the disease, which can increase
her own risk. Additionally, her overweight mother and sisters suggest a familial tendency toward
obesity, further compounding her susceptibility.
Genetic factors contribute to an individual's tendency to gain weight and develop certain health
conditions. However, lifestyle choices can significantly influence how these genetic predispositions

overweight:
Diet: Sally's acknowledgement of an increased appetite for sweets indicates a potential issue with her
dietary choices. Consuming a diet high in refined sugars and unhealthy fats can contribute to weight
gain and increase the risk of developing diabetes. Adopting a balanced and nutritious diet, focusing on
whole foods, lean proteins, fruits, vegetables, and whole grains, can help manage her weight and reduce
her risk of diabetes.
Physical activity: Sally acknowledges that she is not as physically active as she would like to be. Regular
exercise plays a crucial role in weight management and overall health. Engaging in moderate-intensity

Sally maintain a healthy weight and improve her insulin sensitivity.
Stress management and sleep: Sally mentions that recent stresses in her life have affected her sleep and
