Negative Calories- Whats the deal?

I once heard that celery had “negative” calories. That is, the process of eating the food consumed more calories than the food contained. Which seems like an easy concept to grasp, and therefore eaiser to beleive. I later heard that this idea was impossible, and could never occur. Whats the Deal? What foods, if any are best at doing this? What if a food related activity could be included? Shelling peanuts from the shell, peeling fruits… etc.

Hmmm. Two years on this board and only 30 posts. Don’t come around much, do ya?

With all due respect, just use the search engine for “negative calories.” It’s come up a number of times. I doubt that anyone will be able to post anything new this time that hasn’t already been mentioned.

Earl, The website never let me in until recently, within the last two weeks.

OK, sorry if I sounded a bit snarky.

The other point still stands, though. It has come up quite a few times, and I doubt that anyone will come up with anything new this time, either.

A 2x4 takes much more calories to eat than it provides to humans in digestible calories. Not that I’d recommend eating many 2x4s – and certainly not exterior grade or pressure treated wood (toxic additives)

Plain water contains zero calories, and would take a calorie or three to process via the vascular system and kidneys - but drinking enough water for an appreciable rate of weight loss would be dangerous.

I think what you really want to know is “What nummy, better-than-sex delectable that never grows tiring can I safely consume day in and day out for weeks, months or years?” Well, if you think I’m revealing that here, you haven’t been reading my spam. Fork over the $29.95, and we’ll talk.

Probably lots of things have negative calories if you go about it the right way - catch and kill all your own meat; plant and harvest all your own fruits, vegetables and grains; milk your own cow.

since people live on hunting/gathering and farming I would have to say that there is a net calorie increase. Water that is below body temp has to be negitave calorie, unless you must lower your body temp.
