Joe would like to lose two pounds a week. if his present energy intake is 4,200 kcals a day and his energy expenditure does not change, how many kilocarlories should he consume each day to achieve his goal?

He needs to eat 2000 calories a day.

Explanation:

The amount of calories a person needs to ingest to lose two pounds per week varies in relation to gender, height, age, physical activity, among others. However, in general, we can say that to lose at least half a kilo per week, the individual should spend on average 500 calories more than they eat throughout the day, so to lose 1 kilo a week, you need eat 1000 calories less than your body's basal expenditure. Therefore, to lose two pounds a week the individual needs to eat 2000 calories.

However, without physical activity the individual will not be able to lose weight. If the patient maintains a low level of physical activity and consumes 2000 calories a day, she will keep her weight stable over time. If you consume more than 2000 calories a day, it will keep on getting fat.
