Evening Training. (Page 2)

By that argument, you're constantly "losing weight".  You're always metabolically active and burning calories, and moreso during the day.

You guys are missing the point.  "Weight" has to go somewhere.  It doesn't just magically come off.  It generally leaves in the form of urine, stool, sweat, and some respiratory losses.  What you're burning is irrelevant (glycogen, fat, sugar).  It has to leave your body somewhere.  You are not physically capable of losing 3-4 lbs of body weight via your metabolism overnight.  You guys can argue otherwise all you want, but you're arguing against basic physiology.

Losses from sweat while you're sleeping are negligible.  You'd wake up soaked if that were the case.

My point is not far off from what everybody is saying.  It IS water shifts because that's the only explanation that makes any physiologic sense.  It's not losses of water through sweat, breathing, etc. because you just don't lose that much in that manner.  I'm not arguing that the Earth is flat here.

I'm sure people are training at night, drinking a lot during that, and having big fluid shifts causing the weight differences.  The vast majority of fluid loss will be through urine.  How that fits in with what people are saying, I have no idea.  I'm not there to track their urine output.

Bear just gave some diet pill company a new slogan: "Burn 10,000 calories and lose three pounds, all while you sleep. Please make sure to set aside eight hours for proper weight loss."
Maybe the person losing three pounds is weighing himself before bed in extra-heavy pajamas...

Derek -  Oh I agree with you. I just wanted to mention that you do lose some weight while sleeping. Although 4 pounds sounds extreme...

I agree with Derek the world is flat...

This thread reminds me of Monty Python: "Are you trying to suggest that coconuts migrate?"

So you're saying the same thing Derek is saying, that "that guy" is full of crap.
