Agree with MOnica and others here - a "snack" is something eaten between meals. It doesn't matter what it is - cake, crisps or fruit.
Lke MOnica, I wasn't allowed to eat between meals on the grounds that it would ruin my appetite. I follow this habit to this day and try to make sure meals fill me up and are sustaining.
If I am tempted by cake, crisps, bars or biscuits etc, I would aim to eat them at the end of my main meal as part of it, but I am usually too full up by then. But if I decide to leave "room" for them, I don't feel deprived of the odd treat that I enjoy.
I make exceptions when on holiday (eg ice cream).
Lots of snacks give a sugar rush that then leads to a dip in blood sugar leaving the eater wanting more. This is deliberate on the manufacturers' part. Don't fall for it!
If you succeed in having a snack-free February, why not aim for a snack-free life?!
