Question:
does the weightloss/fat come aay through bodily functions...

hi could you let me know how the fat leaves the body is it through poos and wees or is it some other way....if you are losing weight rapidly after surgery is there a need to go to the toilet more often than normal.... do you notice a marked increase of urine when you are losing weight compared to how much fluid you intake... do you feel light headed alot from frequent peeing if you lose weight this way...i know when i take diuretics they make me giidy is this much the same..    — [Anonymous] (posted on November 13, 2001)

I believe, but not 100% sure, that the body will use the fat as an energy or food source. Because of the high protein, low carb intake in the beginning, the body goes into ketosis. Basically what this is is the body is living off it's stored fat. Kinda like when a bear fattens up for hibernation. It's body lives off the stored fat all winter.

When you loose fat, it is not expended like a by product or waste product. Stored fat is an energy source, it is turned into the blood stream and used for energy. It is not eliminated by the body in bowels or urine.

I asked my doctor this same question. He said that excess fat that is being burned is expelled through the urine.

I'm so glad someone asked this! I was wondering the same thing.

Fat is burned as fuel to keep the body alive. You don't lose fat through the bowels or bladder. However, if you eat a high fat meal, and the fat is not digested and stored in the body, some of the fat in the food can move through the intestine without being digested and can exit your body through your bowels. This is what happens when you take Xenical. I believe that D-Switch patients have special concerns about eating fatty foods due to the inability to digest certain fats or certain quantities of fats. In addition, if your gallbladder is removed during your weight loss surgery, you may experience loose bowel movements and explosive diarrhea.

I dont know about you all, but when i eat a lot of fat, when i go to the bathroom it looks like a big oil slick. So apparently it's coming from somewhere...
