Hmmm ... at 5'4" tall and 6 stone 10 (that's 94 lbs), you're desperately underweight and really need to put on 15 or so pounds to be at a healthy weight. At this stage, please listen to your nutritionist - you need more help than anyone here can help you with. We have several health-care professionals on the forum, but none of them would presume to advise you without a personal consultation!
