Answer:
Firstly, as they are sedentary and also a workaholic, I would modify this behavior by telling them to control their work environment and take 10-15 mins walks for their work breaks. The reason being is that now, instead of sitting and doing work all day long with no exercise whatsoever, they will be on their feet for 10-15 minutes every hour, which is a better alternative for their sedentary and busy lifestyle.
Secondly, they are overweight but also have type 2 diabetes, I would modify this behavior by making them change their diet. Keep in mind that they will now be on their feet for 10-15 minutes every hour, which will help them lose a couple of pounds if a correct and healthy diet is also included. As they have diabetes, I have to be mindful of what they eat and how much they eat. I will tell them to replace refined carbohydrates with wholegrain foods. And also, to increase intake of vegetables and other foods high in dietary fiber. Last but not least, I would urge them to drink at least 6-8 glasses of water per day as this will keep them hydrated and away from sugary and unhealthy drinks.
