How is it possible to lose 8lbs in one week?

Quote  |  Reply

I started monday to watch what I eat. I take in about 1500 give or take. I'm also running or jogging about 2 miles 5 days a week. Also, I do weights twice a week.

What I don't understand is how I lost about 8 pounds in one week. Monday morning I was at 158 and today (Friday) I am at 150lbs.

I'm scared I'm doing something wrong. It is a big difference specially since I was expecting to loose 2lbs a week.

What am I doing wrong?

Have you increased the amount of water you're drinking as well? The first week of my diet, I increased my water intake a great deal, and lots almost 6 lbs just in water weight.  It eventually leveled off to a 1-2 lbs a week rate.

Yes I increased the amount of water I drink. I don't understand how drinking water makes u lose water weight though.

It's definitely water weight, and it will level off in a week or two.  The first few weeks of weight loss vary hugely from person to person - some people lose 10 pounds (or even more!), some people don't lose anything.  It's not physically possible to lose 8lbs of fat in one week.

Are you on a low-carb diet?  Cutting carbs leads to significant water weight loss, and would definitely explain the 8lbs.  If not, a reduction in sodium might explain it, or your increased water intake as heatherkparks said.  I know it's counterintuitive, but when you're not taking in enough water, your body hangs on to what you do take in to make sure you stay hydrated enough. When you are drinking enough, your body stops retaining water.

1500 calories is pretty low for an active person - how tall are you and how old are you? You might want to increase your calories.

I'm 5'6" and I'm 26. I'm not on any specific diet. I'm just cutting on calories in.

My only doubt about the water is that I have been working out for about 6 months now and it makes me very thirsy so my water habit has not changed that drastically but it has.

I was thinking it might have to do with my monthly friend.

Also since I added weights I was thinking that it might in any case make me gain musle weight.

I guess weeks will tell.

i'm thinking i may have some water weight too


how can i fix this? i mean i know obviously drink more water, but how much and how often?

like would it work if i drank a cup of water every hour for a few days?

People really ask this question too often I think.

When you start on any weight loss program, you will lose a seemingly significant amount of weight in the first week. This is water weight, (Which is not only affected by your water intake, I should mention), and it's nothing to worry about. If you gain it back after a day of eating a lot, that is also nothing to worry about, because we're talking about temproary and not permanent weight fluctuations here.
