I have the same problem... my husband lost a lot of weight and ate fruits and vegetables taht made a huge difference alhamdulillah... it goes back and forth but alhamdulillah he is doing better now so you should try these too give him fresh fruits and vegetables, boiled chicken, vitamins. Insha'Allah Allah will help all of us when the time is right it will happen Insha'Allah..
