Question: how many calories does a 50 year old woman need to lose weight?
Answer: At age 50, you need 200 fewer calories a day than you did when you were 20, assuming you are equally active. After age 60, you need 400-500 calories less. If you're moderately active, up to age 50, around 2,000 calories a day is good. After 50, you need to decrease to 1,800 calories.
