I had been warned that post weight loss surgery that some people have an increase in BO. I just left the gym and I reek of BO. I am not up to my old treadmill routine of hills and spead but I am working hard enough to raise my pulse. Thing is I barley sweated even though in the past this long of a work out with a pulse level I achieved I would of been soaked. So is the increased BO because My body is not letting go of its precious fluids and the sweat is concentrated stinky stuff?Does this stage last long? What has been your experience?

I"m not sure if I've ever heard that (but I've been hanging out on this and other boards for about seven or eight years, so it may have come up and I'd just forgotten). I never had that issue. And now that I've lost all that weight, I rarely even break a sweat!

Welcome to ketosis. Stronger body odour, bad breath, smelly urine, etc. are renowned side effects of ketosis. It’s like all our natural body secretions suddenly reek. We want to be burning fat but it’s a shame the side effect can be quite offensive. Regularly apply deodorants, pop breath fresheners, shower more regularly. I purchased some body wipe towelettes so I could freshen up a little in the toilet at work.
