Hey Tornado! I do the exact same thing! Edy's has a wonderful low-fat fudge tracks ice cream. I won't eat something like ice cream by itself, I will eat it with some protein to avoid an insulin spike. But actually ice cream has a fairly low GI, lower than whole wheat bread, most fruit, potatoes and plenty of other "healthy" foods. I also rely heavily on natural pb and macadamia nut butter to bring up my fat if I need to at the end of the day. I'm actually trying to gain weight and am having no luck. So I doubt it will adversely affect your weight loss. If you want to eat cleaner, oatmeal with nuts or nut butter and ricotta or protein powder is a good bedtime choice to up the cals. Good luck!
