i used to practically live on pistachios and crisps etc and i rarely had a proper food as my parents are too lazy to cook, i didnt feel hungry but i felt dizzy and really easily tired
now iv started cooking for myself, and gtting into a good routine (try to eat at least one regular meal every afternoon) and i find myself actually feeling hungry at this time of day if i dont eat.
its important to realise that even if u dont feel hungry, it can still be doing damage to your body if u dont get enough nutrients
