Frequently asked questions

How many calories should a 100 kg woman eat to lose weight?

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 2,570 calories, so a cut sits near 2,020 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.

How many calories should a 100 kg woman eat to build muscle?

A lean bulk gains about 0.25% of bodyweight a week, which at 100 kg is a surplus of about 275 calories a day. That puts a woman at 164 cm who lifts four days a week near 2,845 calories a day, with 160 to 220 g of protein.

How many calories does a 100 kg woman burn at rest?

At rest, a 30-year-old woman at 164 cm and 100 kg burns about 1,715 calories a day: that is the BMR. With a desk job and little exercise, the total for the day is about 2,055 calories.
