How much weight can you lose if you don't eat for about a week?

Question

I don't think i'm gonna do it, but i can't find out anywhere how much u could lose. So how much could you lose if you don't eat for a whole week, but you still drink stuff(mainly water though) of course.

Answer 1

DONT DO IT!
You would lose weight but as soon as you started eating again you would put on every last ounce and more. The body would store all it could so you would be worse off!

Answer 2

That would do absolutely nothing for you. You might get sick or even put on some inches if all your drinking is water. Once you began eating again whatever food you eat will have to try and work twice as hard since you did not nourish yourself and you will gain almost all the weight back. That's a very unintelligent thing to do. Try exorcise and eating healthier for good, you cannot become fit in a week.

Answer 3

well, that depends on your metabolism...

but let's say you usually eat 2000 calories a day. in one week, that's 14, 000 calories. So just by not eating for a week, you'll theoretically lose 4 lbs (3500 calories = 1 lb). You'll also have to take into consideration how many calories you burn in a day...that'll probably lose you another few pounds.

but if you're not going to eat, your body will conserve energy and your metabolism will slow down. maybe a lot. and you'll probably burn more muscle than fat. when you start eating again, it'll stick with you more because your metabolism has become sluggish.

you're better off eating slightly less and exercising more. but you probably knew that.

Answer 4

Possibly none, as the body will go into what's called starvation mode and will try to hold on to whatever fat storage is there. If its forced to go into the reserves, without nutrition of any kind, it will start by eating up whatever muscle you have. Thus, at the end of the week, maybe you will have lost a couple of pounds on the scale, but it will be more water weight and muscle, thus leaving you looking flabbier, if actually weighing less.

Answer 5

I would like to say that there is no such thing as a stupid question, but this question of yours is almost there...I have no clue how much you will lose, probably mostly water weight which is about 10lbs, but if you do no eat for a week, you will F-up your metabolism which will make you gain weight back quick once you do start eating.

Whoever you are trying to impress, its not worth it.

Answer 6

Less than if you eat because your body gets the message to stop the digestion system and to retain any intake. Eat small amounts frequently to keep the system digesting. Celery takes more calories to chew than it supplies. Eat celery 5 or 6 times a day for a week and you will lose way more weight than eating nothing.

Answer 7

You can't find information on this because you'd end up in the hospital. Even people who fast for religious reasons eat at night.

Do the math. Figure out how many calories you burn in an average day, multiply that times 7. Then see how many lost calories = 1 pound.

Answer 8

about 20-30

Answer 9

Useless way to lose wight, you'll just put it straight back on when you eat again (you wouldn't last a whole week, by the way) Best way to lose weight is to lose it gradually by sensible eating and excercise. This is assuming you really do have weight to lose and don't just think you have.

Answer 10

Fasting?
There are diets like that, you drink water with grade b maple syrup, lemon juice and chili pepper for 10 days. It makes most people grumpy. You can lose like 10 pounds and shrink your stomach. Best idea though is ask a nutritionist, find a sensible diet and exercise.

Answer 11

Depends on your basic metabolic rate. Male adults average around 2,500 calories a day, females about 2,000. For 7 days, that comes to 17,500 calories, or 14,000 calories, respectively. A pound is equivalent to 3,500 calories, so 17,500/3,500 and 14,000/3,500 comes to 5 pounds, and 4 pounds respectively. That's the most one can lose in a week if nothing is eaten, assuming no exercise is done beyond normal daily activities.
