No real experince (to the extent you are describing) but I often skip meals when I am busy. I also find it is a vicious cirlce as if I skip breakfast I can easily skip lunch as I simply don't feel hungry (almost as if I haven't "woken" up my appetite), and can go right through until my evening meal with dh at a bout 8pm (I AM NOT ADVISING THIS IN THE SLIGHTEST).
If you haven't got much of an appetite, try something like smoothies at breakfast and lunch. I bung in a load of different fruit, always include a banana, one of those prebiotic yoghurt drinks (actimel or such like) and a handful of rolled oats and blitz. I find it much easier to have effectively a drink meal rather than "solids" if I don't feel like eating.
