desertmountain, you can drizzle melted dark chocolate on just about anything. Raspberries would be good and it would look very pretty. Meringue is also fairly low cal; you could make meringue shells to put them in. Angel food cake is fat free (though this and the meringue do have sugar). Frozen fruit bars are good and about 60-70 calories.
And now that you don't have to be perfect, you can be good.
