how to lose 25 pounds in 3 weeks?

25 lbs of fat in 3 weeks would be impossible unless u were extremely overweight, and willing to lose A LOT of muscle mass. However if you start exercising and dieting, from a point where you were not living healthy, then a lot of water weight can be dropped probably around 10 lbs , then in addition 2 lbs can be safely lost for a girl each week (more or less depending on body fat %, overweight people can lose a lot more fat per week then someone at lower body fat %’s)

Start running. Keep a food diary.
Aim for at least 1500-1800 calories a day. Eat carbs in the morning, rather than at night, break up your meals in to small portions and eat throughout the day.
Drink alot of water, and then drink some more.

Do cardio workouts 5X a week, and incorperate weight-lifting. If you are very overwieght you will shed fat fast at first, but as you condition your body you will need to work harder and harder. ( Don’t worry you will be stronger and be able to handle it. )

I personally don’t reccomend losing that much weight so fast, honestly changing your body requires a change of lifestyle, and eating habits. Forever.
Fat cells do not disapear, they shrink. So there is very good potential to gain the weight back as fast as you lost it, if you do some crazy rapid diet or exercise routine that you don’t plan on doing FOREVER.

Also, you need to be building lean muscle tone as you shed fat, this is what will shape your body.
I know you want it fast, but stay persistant, and it will come, and it will be well worth it.
You don’t want to lose weight that fast either so you don’t get crazy stretch marks all over or lose skin everywhere.
Gaining 25 llbs didn’t happen in 3 weeks, don’t expect to lose it in 3 weeks.
But you can do it!
I wish you all the best.

Try this, you can feel and see results in about three days. Muscle will outweigh the fat so don’t let the scale discourage you :).

For exercise, try switching it out everyday, so your body doesn’t get used to the exercise (Monday Arms, Tuesday Stomach, Wednesday Legs, Thursday Rest, Friday Arms, Saturday Stomach, Sunday Legs). Also, one the days where legs or stomach or arms come back around the second workout of the week focusing in that area, try switching the exercise out too. For arms maybe lift weights (if you have none then use cans and be sure to hold them away from you or they won’t work). For stomach, you can sit on a bouncy ball and do crunches (don’t hold onto your legs), for legs, maybe lay on your side propped up on your elbow and lift the top leg slowly up and down, then switch. If you are can’t exercise an hour, that’s fine but try increasing the time every week or so. If you are old enough to buy equiptment or go to a gym, try that. As you get further into it, maybe you can buy some equipment for mainly those three areas I listed. Also, walk home from places or on the commercial break, get up and run wall to wall.
Also, a REALLY good workout is at youtube.com and search for 8 minute abs, 8 minute legs, 8 minute buns, and 8 minute arms. Try doing these on other days (ex.: Monday arms and workout from youtube, Tuesday legs not workout from youtube, Wednesday stomach and 8 minute abs, Thursday rest, Friday arms no 8 minute arms, Saturday no 8 minute abs, Sunday 8 minute legs. Try doing those how I listed above and don’t do it more than once a day along with your daily workout.

For food, which is very important (70% of weight loss is food intake while 30% is excercise, though both are VERY important), try this schedule.

Breakfast:Whenever you wake up or an hour after.

Drink of choice: One hour after breakfast (all other drinks being water.

Lunch: 1 1/2 hours after drink of choice.

Snack: 1 1/2 hour after lunch (or two hours after lunch).

Dinner: 2 hours after snack.

Try portioning your food, one cup for meals and half a cup for snacks and drink of choice. As you get more used to this, you can decrease your portion sizes.
Also try measuring your calorie intake and try exercising over the amount of your intake to build muscle which burns access fat. You can measure that at where it measures EVERYTHING for you :).

If you drink cokes and need help with that, try slowly decreasing the amount of cokes you drink, one day the usual, and decrease half of the amount of that you usually drink until it’s half a cup a day.

While your exercising, I have a problem with wanting to eat then and I’m sure everyone else does too so maybe bring a mug of ice with you and eat the ice so you get a little munch out of it and you hydrate yourself while doing no harm to yourself or your diet.

Hope this helps and good luck!
Also, at if you do everything it says exercise an hour a day, eat the amount of calories! Just keep in mind that whichever diet you do YOU CAN DO IT!!!! Good luck
I’ve been doing this and so far I’ve lost 6lbs in 5 days Good luck

Check your BMR and eat that amount of calories (BMR is the amount of calories that you burn daily just by breathing, sleeping, etc. so if you eat that much, you burn it plus exercise will be burning more then your intake
Alot of people simply say “eat right and exercise” and they may seem like little help but that’s really all it comes down to; those are the basics of every diet. There are different ways of eating right and exercising but those are just the two things it all comes down to (:
