My Husband Has A Lot Of Medical Issues But My

My husband has a lot of medical issues but my concern is that he is morbid obease. as of last weeek he weighs 359 pounds, he has high blood pressure and week muscle in his heat. His doctors say it is because of his weight and he needs to loose weight. I am doing all I can to feed him food that will help him loose weight but I don't know what to do anymore. No salt, no sugar, no sodium, no dairy. I guess I just need a healthy diet for him that will help him to lose weight without addding more damage to his heart. Can you help me please!
