Probably not Bizman. What more than likely would happen is you would gain muscle from all the protein. I've heard from about several people who went carnivore and lost a huge amount of weight but then as they reached their natural weight they leveled off and gained just a little.
I got down to 154 or maybe 156 once but it was too low. I was doing some heavy climbing on my bike in the California Alps (Sierras south of Tahoe to east entrance to Yosemite) and being that light helped but I felt worn down off the bike. Staying at 164 to 170 via muscle mass increase feels really good.
I don't think folks are realizing that eating a meal of meat once a day isn't eating ten thousand calories. After you get settled into the diet you are eating until sated-which, depending on the person, is 1800 to 2500 calories I'd imagine. You eat until full and then you aren't hungry again for a long time. A 16oz ribeye is maybe 1500 calories or so and some shrimp a few hundred more. I'm done after that. I don't eat ribeyes every day so I'd imagine I pay about the same as a "normal" diet but probably a bit more due to egg prices. For me, it's worth it.
If were to pound down a few slices of pizza to get to 2000 calories, I might feel full for a few hours but I guarantee I'm sniffing out that roll of frozen Girl Scouts Thin Mints nestled in the freezer next to the vanilla iced milk container in a few hours. That stuff doesn't curb my hunger, it increases it.
Again, carbohydrates are heroin to me. I'm not doing this for vanity or to fit in size small clothing, I'm trying to extend my life in a way where I want to feel good as long as I can. I think this is the way for me but I don't think I'm preaching or anything, I think I'm putting my story and my reasons out there for folks that may have shown interest after Getback recounted his fantastic journey. To each his own as I know plenty of folks who are in stupendous health and can handle eating a couple Dilly Bars after a burger and fries at DQ once in a while. I can't, I've tried. My wife eats an old-school Okinawan diet as that's where she's from. A pretty limited diet calorie-wise but maybe that's the secret to their longevity. She eats a little, rounds mound of rice and a bit of pork pretty much every day. Once in a while she'll eat a sliver of dark chocolate.
I'm actually 57 and not 56 as I said earlier.....not sure how I fouled that math. Anyhow, I'm on one prescribed drug and that's Xarelto due to increased chances for blood clots after having a clotting event earlier in my life. I've had 3 pulmonary embolisms but not again since starting the Xarelto about 10 years ago. I was able to stop needing the statins, beta-blockers, H2 antagonists, proton pump inhibitors and SSRI's along with CPAP some 20 years ago or so and I haven't looked back.
I'm out. If anyone is further interested, I suggest all the links provided previously in this thread. Again I stress: "to each his own."
