Start from maintenance and take off enough to lose about 0.5% of bodyweight a week. For a 30-year-old woman at 164 cm who lifts four days a week, maintenance is about 1,820 calories, so a cut sits near 1,545 a day. Weigh in daily, compare weekly averages, and adjust by 100 to 150 calories if the trend is off after two to three weeks.
