I'm sharing the results of this mornings research to improve the health of the males of the board:

I volunteer

Please spare "us" the details.  

And weighing myself before and after a dump, has scientifically proven weight loss.  
I haven't done the research on the following yet, but I suspect that pissing, (squirting too? Or is that the same thing?) sweating, puking, cutting your hair, clipping your nails, and shaving, will also result in weight loss.

You must eat properly to see a difference in your weight.  A bodybuilder's saying goes, "You can't work out a bad diet."  Remember that 1 double cheeseburger, chili fries, and a large soda may contain as many as 2000 bad calories and that can take hours to work off in a gym.

Lots of options for working those thighs, glutes, arms, chest, and of course the heart.

I excersized daily when 400+ pounds. It wasn't until I changed my diet did I really see progress. A good mix of low glycemic index c
carbs, healthy fat, fiber, and protein in every meal, controlled portions, and a balanced diet are the key to weight loss. One fast food style meal can do nasty things. Excersizing is important but you can't do enough to undo a bad diet.

Yup.  A 170lb runner burns about 3000 calories running a marathon.  All the exercise in the world isn't going to burn it all off if you are shoveling it in.

...Third World country and come back with E.coli, C.diff or Giardia. Or take a cruise and hope you get Norovirus.  Leave it untreated, buy a lot of Depends and you'll be amazed at how much weight you lose in a very short time.  And you can eat whatever the hell you want while you're dropping the lbs.

Sweet you still did some movment so here what you lost  
.5 oz in cum
1.6 oz of fat and carbs 200 cal
1.9 oz of sweet which not much consider how big the body is.

... You'll lose about 30 lbs... but the problem is where do you think all that weight is going? The more she swallow, the fatter she is getting!
