Re:when cutting is daily calorie intake important?
I personally think consuming maintenance is fine, and the extra cardio will suffice for weight loss. You'll be maintaining your resistance training, well atleast you should be, this at an estimate will burn off around 200 calories per workout, conbined with cardio, and the effects the boost in metabolism post weight training and post cardio will have. You may be exceeding the limit set down by hamilton. That is my experience of cutting anyhow.
My advice, consume maintenance and see how the results, if your progress slows or stops, consume another 200 - 300 calories less or up your cardio.
