He may be just too tired to get up and do things! I agree with you, his diet needs urgent attention. He may also be suffering from a light depression - it is not uncommon in older people. You can assist him by giving him a low salt diet for the next few days and ask his GP to prescribe a diuretic in the mean time to lessen the load on the heart. He will have to cut down on his fat and sugar intake - it is just very difficult to make a drastic change at their age - maybe making smaller changes slowly will be less traumatic.
