Depends on the energy consumption of her body. If she is ingesting less calories than she is expending then she will start to use her body's energy stores (fat) to make energy to keep her cells working happily. Going less than 1500 k/cal a day isn't healthy, so anything above this is reasonable as long as the diet is balanced, vitamin and mineral requirements are being met, and you are working off more calories than you are consuming.
It takes 3500 calories to lose a pound
It depends on how long the 160 pound female eats 600 per day for. If this helps 1 pound = 3500 calories
You should consume seven calories per pound to lose weight, so 1655 calories per day.
How many calories does a 110 pound woman need a day to maintain her weight? Like 1500 calories..
One pound of fat is equal to about 3,500 calories no matter what your current weight is. If you can burn that many (or consume that many fewer) calories in one week, you will lose a pound of fat in one week.
If you calculate your BMR this will tell you how many calories your body needs a day to maintain its weight. If you then consume 500 extra calories a day for a full week you should gain around a pound in weight. So I would say the answer is 3500 calories.
There are about 3,500 calories in a pound. Burn 3,500 calories more than you take in = loose one pound. Take in 3,500 more calories than you burn = gain a pound.
The standard is 3500 calories to 1 pound of weight.
A pound of fat contains roughly 3500 calories, so provided your weight is currently stable, you should aim to reduce your calorie intake by 500 calories a day to lose a pound a week. Adding in extra exercise will help too.
The weight gain from food is not determined by the weight of the food, but by the number of calories in food. 3500 calories of food are equal to about one pound of weight (of the person, not the food).
