If you are trying to lose, then you'll have to be more accurate than that.
This is interesting...I don't count calories and am able to lose weight. But, it's interesting that generally we feel it's necessary that we count calories if the goal is to lose weight and yet to gain weight all we need do is increase our food intake, whereas on the flip-side, all that is necessary to lose weight is to reduce intake slightly, in much the same way as for gaining weight.
Just based on the diet aspect, obviously, since extra cardio thrown in, or weight sessions, or general increase in activity will all have an effect.
