Even ice-cream has to be actually pulled out of the fridge, scooped out of the punnet into a bowl. This may seem like a small hurdle - but it's obviously enough to keep you from eating.

Instead - try getting a bunch of non-perishable food (eg mixed nuts or dried fruit/trail mix) and leaving it in an open jar somewhere easily accessible (eg on the bench). Every time you walk past it - grab a small handful and nibble on it.

From there, you can progress to a bowl of pre-cut-up fresh fruit or veg (keep a lid on it so it doesn't gather flies) for a healthier option. (cut it up all at once at the beginning of the week - leave out a day's worth each morning).

...and that should get the ball rolling.
