Answer:
14 days
Explanation:
Jenny's goal is to lose weight. When a person loses weight, that means the person needs to have more calories burned/expelled than calories consumed.<u> </u><u>The person may also restrict her calorie intake and in Jenny's case, this is her method of losing weight.</u> She decreased her energy intake by 250 kcal per day.
<u>Remember that in order to lose 1 lb of fat, one needs to lose 3,500 kcal/calories.</u>
Thus, we can divide 3,500 kcal/calories by 250 kcal per day in order to know how long it will take for Jenny to lose weight.
Thus: 3,500 kcal ÷ 250 kcal/day = 14 days
This means, Jenny needs 14 days in order to lose 1 lb of body fat.
