While researching your assertion, I came across this ridiculousness. Children and post-menopausal women need 2000 kCal per day.  https://www.theatlantic.com/amp/article/243092/ You are a 55 year old female who is 5 feet 4 inches tall and weighs 240 lbs while being Sedentary. 2000 Cals.  You are a 10 year old female who is 4 feet 10 inches tall and weighs 130 lbs while doing Moderate Exercise. 2000 Cals 2000 kCal is to much!!
