Ask to go on a dafne course this will help you mo end but in actual fact I dont find it work involved at all basically all you need to know is the pack carbohydrate which every food has ! Buy the carbs and cals app or book too that is really beneficial it sounds a little over powering tbh but also a bit scare mongering it realy isnt that hard to get the adjust ment right, if you work yiu shoild still ne entitled to some sort of pay as its to do with your health if yoj do do the course sorry just seen post good luc keep us informed x
