Is your father still working? What's his height and weight? If he has high intelligence, then don't bother prescribing him what to do. You only need to pitch and convince him that hitting a certain BMI is a necessary business outcome. Some men are hunters, not farmers. They need something to chase, not just hang around and tending gardens. Exercise has been not shown to contribute much to weight loss. On the other hand, lack of sleep has been associated with weight gain. Ask your father to consider replacing soda with water. It's magic for most people. The first few days, water will taste terrible. If he can't stand it, make a spritz by adding fresh lemons. Buy a set of scales because he will definitely see the results of this one small change. Also, drink more water. It helps cut down the appetite.
