Weight Loss through Respiration

[wjgo 272]

Does bariatric surgery enhance weight loss through respiration? I have experienced what I thought was unusually weight loss pre-op when I could only conclude that I had to have breathed it out. I hadn't paid much attention to it. With a larger diet pre-op, there was more variability of food weight and volume, and BM's occurred more frequently (mow, infrequent and scary). But now 1.5 months post op, I am on a routine, I know how much Water and meals I get, and I am very good at measuring it (better than pre-op even). And I am definitely losing weight by respiration, no BM's, no sweating, any my urine volume does not come even close to what I drink. I am losing weight between stalls, and not even urinating much. Pre-op, I remember that I seemed to urinate longer. But I never measured it, so its ancedotal to me.

I read some research online that for 10kg fat that is metabolized, 84% of that is exhaled as carbon dioxide, the rest becoming water. The process would require a total of 11kg of water.

This seems more apparent post-op than pre-op. So, does bariatric surgery affect the normal weight loss through respiration by the physical changes to the body? Or is the dieting itself somehow enhancing it? And should I be doing breathing exercises to try to engage my entire lung capacity?

I think fat once converted is only lost to respiration because the body uses the fat for energy. i don't see how increasing lung capacity will improve fat loss (other than through exercise which causes increased calorie defit) not because you have increased lung capacity as such.

Fat loss is due to fat being converted to carbon dioxide and which is because of the overall calorie deficit not because of respiration of the carbon dioxide. If there is no deficit then there is no carbon dioxide to be 'breathed out'. That is just how the body rids itself of the by product of the fat being converted. If you increase and engage entire lung capacity that may increase fat loss but not because of the respiration but because you are increasing calorie deficit.

Respiration is more about where the fat goes not that respiration causes the fat loss. It's the calorie deficit that is causing the fat loss.

You are not losing weight by respiration, you are losing weight because of calorie deficit and probably other metabolism mechanisms, respiration is just how the body rids its of the by product of fat loss.

You may be over thinking WLS. I've read the study. People with larger lung capacity are not naturally thin.

Work your dieticians surgeons plan. Exercise your entire body.

That's for sure. My lung capacity is huge. The respiratory therapist at the hospital was amazed.
