Ive lost 21 lbs now on my pre op diet. Is it all water weight or is some of it fat? Ive heard losing more than 5 lbs in a week is unhealthy is this true?

3500 calories is 1 pound of fat (and many of us store Water with the fat) So no it's not all water weight. You are eating 900 cal a day. You probably "need" around 2500-2700 (just a guess, a wild guess) so you have a deficit. Probably 1/3 to 1/2 of it is fat, the other water.

HOWEVER! You need to lose the water too. So whatever it is (water or fat) you weigh that much less NOW than you did 12 days ago.

you know I do weigh 459 lbs now 438 whoo hoo. all I can think is when ya weigh this much ya lose quicker in the beginning

THat is awesome! I am on the first day of the 2 weeks of liquid. not so fun so far. I was doing well this morning, but now Im hungry!!

Hopefully I will have similar results!!

:sneaky:

marmar...people lose at different rates. You are losing because you are getting only 900 cal a day, and that is amazing! See, your hard work and struggling to stick with it is paying off. I'm 54 and not supposed to be able to lose fast because of menopause but when I do my atkins type diet weight drops off! :sneaky: So your loss probably will slow down some, esp when you get food...but you are working hard and earning that loss so enjoy every OUNCE of it! You are now closer to 400 than 500...!!! You'll be out of the "fourest" (as they call the 400's) and into "threedom" before long. I am almost where you are, just 100 less...trying to get out of threedom into twoterville. We will both make it, and soon too! :sad:

wow that is great, so what are you doing? shakes, clear liquid? i need help, i have like 10 lbs to go!

When your body stores carbohydrate, it also stores it with Water, I think 2 molecules of water, 1 carb, but maybe its the other way round, hmmm, anyway, long shot is that's why you lose so much weight when you embark on a low carb diet - water. There wont be a lot of fat in that, perhaps 1/3 and you'll lose a bit of muscle too from the ultra low calorie diet, but its all part of the process.

Its not "healthy" as a weight management strategy and longer term, its not very effective. Virtually nobody keeps that sort of fast weight loss off, unless they're following it up with weight loss surgery. You're not doing it for healthy weight loss, your'e doing it to shrink your liver. Just when you cant take it anymore, you have your surgery and can keep going.

But for many people, once that water weight is shed, the fast loss slows down and they're disappointed with after surgery results. Dont be. The weight loss that really matters is the steadier kind, that's more fat.

For some, a high protein low carb diet is healthy. We all have to find what works! However it's not really rational to think a person can live on 6 shakes a day forever! But for now, enjoy it. And..it's gone!

Good Luck. You will be okay. I know how you are feeling. I just had my surgery Thursday and prior to that I was on a 2 week liquid diet. It was difficult but you will pull through it and it will be all worth it.
