Things a picky eater can snack on when trying to lose weight?

Carrot sticks. Snacks are for bad cooks.

water

almonds

There are only two. Carrots and Heart of Celery.

Otherwise, just cut your normal meals by 10%.

Drink only Water (iced)

Weigh yourself only once a week. (fluctuation daily/hourly may confuse)

The only exercise needed is to walk three to ten miles a day, get a pedometer to what you are doing.

Lay there, 69 nude on a couch, and whenever you get a pang of hunger at all, do some oral for your other. It might work better if the smells is more stink, and do it, a form of classical conditioning of bad smell for hunger.
