My friend doesnt care about how she looks any more – how can i help her?

Ok ill just explain – my close friend became christian about 3 years ago. She has not dated for about 3 years since she broke up with her bf.

Since then she has decided to spend all her time devoted to religion and the rest on her job. She has stopped exercising, eats really bad and doesnt take care of her skin anymore or pay attention to fashion. She used to be really pretty but she is one of those people who puts on weight really easily so she is pretty overweight now.

She has not had a date for 3 years since she broke up with her ex. It concerns me that she doesnt care about her appearance anymore because guys care about looks and i dont want her to end up alone. Shes a great person and deserves to find someone good but she does not look good at all now and doesnt seem to care.

Any advice on how to tell her or help her?
