OK i just want to start out by saying that i am one of you! i Work out 6 days a week, lift weights, cardio, run ect. ect. I eat really healthy, leans meats, whey, non-fat yogurt, fish, shrimp, canned veggies, canned fruit(college student...fresh is too expensive), oatmeal... i pretty much stay away from packaged foods (except the canned but i always get organic or low-sodium/light syrup)
my question is i tend to cheat alot, i go a week eating really healthy and excercising them sometimes i just pig out. I need a stopper and i love ice cream, especially the ben and jerrys, so here is my question, if i eat really healthy around 1500 calories a day, excercise and eat a whole container of ben and jerrys on once a week (on average about 1000 calories a container) will this be harmful to weightloss, and when i get my system flushed out will it just make it crappy again?
I need to add, i have muscles and can almost see a 6-pack, but i have a little flab around the belly, thighs and buttox, and i need(well dont need but want to) to lose the fat in 2 months for springbreak, ive been working out about 2 hours a-day, running around 3 miles. will i still lose weight if i eat one thing of ben and jerrys once a week.

its not necessarily bad for your figure to eat a 1000 calories of ice cream because you are working out like you said 6 days a week. but think of the impact its having on your health. how many grams of sugar does that container have in it? think of it in terms of that. how many other artificial things does it have in it that are bad for your body and health
