Each 10 years of age lowers the estimate by 50 calories of BMR, which becomes about 60 to 86 calories of TDEE depending on activity. Height matters a little more: each extra 2 inches adds about 32 calories of BMR. Activity matters most. A very hard daily trainer at this weight (35, 5′4″, “extra active”) would burn around 2,757.
Using these numbers
These are estimates for the average woman with these measurements. Your real maintenance could be a couple of hundred calories either side. The way to know is to eat close to your estimate for two to four weeks and watch your weekly average weight; see how to find your maintenance calories. If you want a gradual change, the calculator above shows gentle ranges and won’t show a target below about 1,200 calories a day.
Frequently asked questions
How many calories should a 170 lb woman eat to maintain weight?
Roughly 1,561 to 2,667 calories a day across the heights, ages and activity levels in the tables on this page, by the Mifflin-St Jeor equation. A 35-year-old woman who is 5′4″ and lightly active comes out at about 1,995. Your own number depends on your height, age and activity; enter them in the calculator for a personal estimate.
How many calories should a 170 lb woman eat to lose weight?
Starting from about 1,995 calories (age 35, 5′4″, lightly active), a gentle reduction of 250 to 500 calories a day gives roughly 1,495 to 1,745 calories, often linked to about 0.5 to 1 lb a week at first. Results vary, so watch your trend over several weeks.
Is 1,700 calories a day enough for a 170 lb woman?
For a 35-year-old woman who is 5′4″ and mostly sedentary, it is close to estimated maintenance (about 1,741). More active women of the same weight burn more and would likely need more to keep their weight stable.
How many calories does a 170 lb woman burn at rest?
A 35-year-old woman who is 5′4″ and 170 lb has an estimated BMR of about 1,451 calories a day by Mifflin-St Jeor. That is the energy used at complete rest, before any movement or digestion.
