I think this calorie obsession is madness. Really think about it, you don't need to read on packaging to know if something is healthy for you or not. You should already know! Anything fried is generally unhealthy whether its frozen or not. Eating healthy is easy, no fried food, lots of fresh fruit and vegetables, fish and lean meats cooked well and slowly in the oven.
If it's weight then less carbs normally does the trick. Atkins is bad for you so it's just a matter of cutting down not cutting out! Also do not eat heavy in the evenings. So what out of all that do people actually not already know?? ;-)
