30 yrs, 6 '1", nearly 230 lbs and works 12 hours a day. Weight loss is extremely difficult for him as I cannot make him go on a diet or exercise which may zap his energy. I am afraid he is becoming obese. It is very difficult to make him walk everyday and he eats reasonably less for a man of his weight. In the morning he does with a bowl of cereals and the afternoon something veggie from his work place. He eats non-veg twice-thrice a week.
What is a diet that can be effective? And an exercise?
