... now is 56. doctors in my country said her recovery is too slow, it may turn to chronic heart failure. she's overweight so i think that lose some weight may help her a lot (she's 1.63 m and 85 kg). can you give me some advices about lose weight safely please? i'm looking forward to your answers. my english is really bad, i hope you understand and forgive me if my writing is impolite. thank you so much
