Being fat is a billion dollar industry - one side puts it on, the other side gyps a bunch of people annually to take it off, and how much weight is actually lost? Not so much.

See the above responses - I recommend Weight Watchers. Their plans are diabetic-friendly, generationally tested (Mom did it when I was a kid) and there are a bunch of folks I point to on my own FL who done spectacularly on it.

And they have centers/meetings everywhere.
