Because I'm eating to strength train (not to lose weight at the mo), I'm eating so many meals and drinking so much water that I don't have the time or hunger to fancy a 'snack' often (what with trying to fit in regular lean proteins, five portions of fruit/veg, good fats and fibre each day) - but some of my 'meals' are basically snacks anyway. Having said that then fruit (apple, pear, satsuma etc), oat bar, a boiled egg, or a packet of beef jerky are my faves. If I was eating to cut, then, well, probably the same but as part of my calorie allowance.
