How many calories do you need to eat a day to lose 50 lbs in 2 and a half months?

Answer 1

This goal is not possible to achieve in 2.5 months by only changing your dietary habits. Read on!

Let's lay out the data: (FYI - this assumes you need 2,000 calories per day to maintain your current weight)

50lbs @ 3500 calories per pound = 175,000 calories need to be eliminated or burned off:

2 and a half months = 75 days

175,000 calories divided by 75 days = 2,333 calories per day.

Assuming you are eating 2,000 calories per day right now - you can cut this down to 1,200 calories per day (talk to your doctor before doing this). That removes 800 calories per day.

Now you still need to remove 1,533 calories per day! (2,333 - 800). Simple - exercise 1,533 calories burned per day.

If you only eat less - without any of the exercise you might lose about 17 pounds in 2.5 months.

Slow and steady wins the race. Try lengthening your goal to 6 months. Eating 1,500 calories per day, exercising 400 calories burned per day - in 6 months expect to drop 46 pounds!

Answer 2

Regardless of your starting weight, it is inadvisable to try to lose more than 1-2 pounds a week. Since one pound of fat is approximately equal to 3500 calories, if you reduce your caloric intake by 500 calories a day, you should lose about a pound a week.

Answer 3

It all depends on your size, shape and amount of exercise you do. For a female a good guideline is around 1600 calories and for a male around 2100 calories, but check this by going to your doctor.

Answer 4

If you want to lose a lot of weight, I recommend the juice fast. If you're truly serious about this, buy a juicer, and juice fruits and vegetables and drink only juice for 10 days. If you want to lose more, go for longer. (You might want to watch the movie Fat, Sick, and Nearly Dead. Sounds stupid, but it's helpful) The two guys on this documentary lost a lot of weight, only drinking juice for 60 days and exercising.

Answer 5

if you can burn 500 calories a day it should take about a year.

1 pound=3500
