I have lost just over 40lbs in the past few months..

I was using 12lbs of lead using AL80's.

Any rough guess on how much lead I should drop? I won't be able to get wet until next weekend and just wondering.
 
That's a difficult question to answer since your change in buoyancy depends on the type of tissue you lost. Muscle, Fat, and water will have different buoyancies and depending on what porportion of each you've gained/lost, I don't think there's any really good way to predict.

Remember that even though you had a net loss of weight, you may have gained or loss some muscle mass in addition to fat tissue. As well, your state of hydration may affect your calculations as this is generally not a permanent type of weight loss.
 
Depends. Was it mostly fat, mostly muscle, mostly bone tissue?

At the very least, you'll need 4# of negative buoyancy to offset your empty tank. Whether that sits on a belt or not doesn't matter.
 
Since a pound of fat weighs the same as a pound of muscle (a pound of fat just takes up more space than a pound of muscle) I can say that I lost 40lbs of fat. Since I have been working out with the weight loss I am sure I didn't lose muscle and would have actually added muscle.
 
Wow, that's alot of wieght to loose, how did you do it?

congrats on the weight loss.

actually the question of fat vs muscle does make a difference as fat is alot more bouyant, so if you had a large % of fat before (needed more weight) and lost it (need less weight) and if you toned up, converted to muscle etc. (need less weight)

- the weighting will be a bit of trial and error...start off with a few lbs less (say 2) but make sure the remainder is in small units (e.g. don't stick in 2 5lb weights, use 5 2lb weights or somethign like that...then remove as needed if you feel too heavy
 
Last year I lost 40 lbs and ended up having to increase the lead in my weightbelt ... losing the "bioprene" meant that I got cold easier, and so I had to add more undergarment underneath my drysuit ...

Congratulations!
:D
I'd just start with the same amount of lead you used before, see how the dive goes, and figure it out from there.

BECAUSE it takes up more space, you can't.

What kind of exercise? Your body will burn muscle before it burns fat. Chances are if you haven't involved any resistance training, you've lost both.

I'll agree with DeepBound. Go with 12# to be on the safe side and remove it as applicable.

What did you do to lose the weight?
