Can somebody help me please?

I'm a 19 year old girl that is 5'6" tall, and I weight 216 lbs (but I look like I weigh less than that).

Anyways, my weight goal is 125 lbs. I saw a dietitian who said I need about 1600 calories, but since I told her that sounds like too much, she said does 1400 calories sound better, and I told her yes.

I know to lose weight, you have to burn more calories than you consume. So how would I burn more than 1400 calories in one day? Wouldn't it take more than 30-60 min. of exercise?

You got it all it all wrong. There's something called maintenance caloric intake, which is how many calories you'll need just to maintain your current size. A rough estimate would be that you need 3500-4000 calories just to maintain your weight of 216lbs. Now in order to lose 1 pound you'll need to get rid of 3500 calories. Spread that out over the course of one week you'll need to cut (3500/7 = 500) 500 calories a day on average. So your new caloric intake value will be inbetween 3000 and 3500 calories. Don't forget that if you cut too many calories too fast your body may go into starvation mode and try to hold as much fat as possible.

In the case given to you, using my estimate and your goal.

3500-4000 calories maintainence
1400 calories acutal intake

3500-1400 = 1100
and
4000-1400= 2600
per day

In a week you stand to lose
1100*7=7700 approximately 2.2 pounds
or
2600*7=19200= 5.4lbs
respectfully.

Good luck!
