Read the scenario below and answer the questions that follow. Glenn is a 38-year-old truck driver. He spends long hours each day driving in busy city traffic. When he was young he really liked eating meat pies, hamburgers and chips and drinking chocolate thick shakes for lunch. He ate lots of food because he had a big appetite. This was not a problem because he rarely put on weight even though he did not exercise often. He still eats a big lunch each day and finds that eating smaller amounts or more nutritious foods is very hard. He is now 40 kilograms overweight and has been diagnosed with type 2 diabetes. He has been told he is at risk of heart disease if he doesn't change his lifestyle.

1. What factors have led to Glenn's poor level of physical health?

2. Devise a realistic plan that includes a range of strategies Glenn could adopt to improve his health. Keep in mind his occupation and current lifestyle habits.
