Well, I snack constantly, but my diet consists mostly of vegetables, fruit, nuts, meat and water. I haven't had weight issues yet. If my snack consist of one carrot, one apple, handful of nuts or one orange, it's not that bad. Doesn't hurt that apples and oranges are delicious. But then again, I'm not trying to lose weight, just eat healthier than coffee and donuts every day. My dietary requirements might be different if I actually also did strength training in addition to cardio (running & walking).
