Hi, I'm new here. I am 76 years old and suffering with painful arthritis in one hip so my mobility is restricted. My problem is that although I don't have any weight to lose my (I have skinny arms and legs but a lot of tummy fat) diet is very hit and miss healthywise. I would like some help to improve my diet and I also need to take more regular exercise. I like to walk as much as I can but this can be very painful on some days.
