I'm also pretty much stalled around 40. Lately I haven't been keeping close track due to the travel and all, so I haven't given it much thought. I'm so happy to have lost 40 in less than two months anyway, and feel so much better.
I've also become a preacher of the diet... A lot of people are interested in asking me about it when they hear me decline any sugars or carbs. I've converted quite a few people. Oh, this means you may see some strangers in this section of the forums--hope nobody minds, but with the wealth of info here, I've invited some friends and family to read this stuff.
I think I have my dad's interest, which is my top goal. He's just been diagnosed with Lymphoma. A low-carb diet is a great fight against the disease itself, plus I've been learning it can do wonders to curb the effects of chemotherapy. I've also brought some other family around, as in Cuban culture we tend to eat shitloads of sugar and carry a lot of excess weight around our middles--a recipe for early disease or worse.
Anyway, I've rambled...I'm stuck too, so any of the extreme measures would be interesting to hear. TJ, whenever you have time (I know we ask for a lot of your time and expertise here), can you post a new thread on "How to break a barrier" or whatever such items you care to speak of? Thanks!
