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.

for me i have felt invisible when i was clearly struggling,or,i made a great achievement ,and,nobody took to notice me either because they just didn't see it,or,people just turned their back on me.i can see a person being invisible by choice,or,without choice like i did.the people who are invisible by choice don't try to talk to people,don't try to make friends,and,keep to themselves.i haven't been one of those people so i couldn't give you a reason.

hope this and can i get bainliest my dude : d
