I have fruit and yoghurt most days, it fills me up, but its not too heavy on my stomach, on weekends i will have boiled eggs and soldiers or a quorn sausage sandwich. It does take a while for your body to get used to eating breakfast, i didnt eat it for years and i think it messed up my metabolism a bit, but now i eat it everyday after i have done my exercise routine and it really sets me up for the day!!
