You know the liquid oil grease that's leftover when you fry or deepfry bacon? My 9 year old likes to drink it straight up. She drinks, like, an entire cup of it every day. But we were thinking that it might have a lot of calories, and that it wouldn't be good for her to drink it every day, and maybe cut it down to once or twice a week? She's got problems with her weight already (she's technically overweight, though we don't know why. but we don't make her exercise, we just try to get her to drink at least 2 glasses of water a day, you know, for her health), could this hurt her?
