Hi. I don't think you need colour filling, rather you need a doctor to see you, counsel you about your condition and look for a cause for greying. You sound as though you have already lost all hope.. But I haven't! A very respectable 60 Yr old lady I know, who was 92 kg and has knee pain so couldn't work out, lost 16 KGS in about ten months with dieting alone - dieting, meaningful and nutritious. So you definitely can lose weight. So we need to treat you on the whole. You can consult me further on private chat may you need any further help. Best wishes. Dr Govind S Mittal, Excel care hospital.
