Two Weeks In, and some questions
Right. Went snowboarding, first time in my life that being out of
shape was clearly a problem. Went on Atkins _immediately_ (as in, I was stripping cheeseburgers of their buns at lunch). About a week later, once my body had adjusted to the new energy source, I started walking / running. Turns out that whole ability to walk arbitrary distances quickly scales into being able to jog and even run long distances -- constant distance of 8-10 miles, with ever increasing speed, seems to have worked really well for me. I can't recommend this strategy enough; don't feel bad that you can't keep running, just start walking and accept the 20-30% heart rate jump with occasional spiking (Polar makes a great heart rate monitor -- very good for realizing exactly how much you're pushing yourself). Eventually, occasional will become often, and especially once you get going, you just won't stop. This is _much_ better on the ego than running continually to the point of exhaustion and dragging yourself home. Pretty cool, especially since a couple nutritionists have said it's impossible to do sustained workouts w/o carbs. I'm on less than 10 carbs a day (it's just not that hard), and I'm keeping my heart rate up, sometimes way up, for hours on end as I push through the 8-10 every other day. I pretty much *have* to be burning fat, since there's nothing else to burn :-) There is one possible concern. I'm using the best ketosis sticks on the market -- Bayer's Ketostix (http://www.westburypharmacy.com/Merc..._cod e=306381). They're meant for diabetics, they're cheap($10.99 for 50), and they actually _quantify_ how many ketones are in your urine. Before I started exercising, I was averaging 40mg/dL -- the "dark" entry on the ThinZ strips. I'm now somewhere between the two "large" marks on the Ketostix, meaning 80-160mg/dL -- and I stay this dark even if I don't exercise for a couple days. I'm curious if I should be concerned. The strips lighten up considerably if I accidentally consume carb-loaded food (for example, the two avocados the other day dropped me back to ~30 mg/dL), so I can tell the strips are good. So should I worry that my blood is basically saturated with fuel from fats? BTW, is there any science at all to support the assertion that sugar alcohols don't need to be counted? I've been avoiding them for the most part, just because it's relatively easy to. --Dan |

Two Weeks In, and some questions
Why are you on less than 10 carbs per day?
Because my favorite foods (eggs, cheese, steak, burgers, chicken, etc) are pretty low carb as it is? Are you on Atkins? If so, you can (and SHOULD) have up to 20 carbs per day. At 10 carbs, you can't be taking in much in the way of veggies. Don't get me wrong, I've had days where I had very vew carbs, but it was accidental. I tend to use creamed spinach as a source of veggies. I might start partaking in other fare; got pretty burned by the avocado misadventure. Some refs to argue for it, perchance? Also, it doesn't matter how dark the ketosticks are. In fact, if they are CONSISTENTLY dark, you probably aren't drinking enough water. Being in ketosis is like being pregnant -- you are or you aren't, so as long as it's registering anywhere from pink to purple, you ARE in ketosis. I dunno about this. I was under the impression that, assuming hydration was kept constant, more ketones in the urine meant more fat was being burned for energy (whether or not you're on Atkins). Certainly that's what you read from the diabetic docs; the problem there is the body burns fat instead of the sugars available in the blood stream, and this causes Bad Things. Plus, heavy cardio has multi-day effects on my ketosis levels, nicely filtering out hydration effects. I'm a geek, so I'm into quantification of such things. --Dan |

In persons who are not Type I diabetic, there is a feedback loop, where if ketone concentration gets too high, the body ceases metabolizing fats and releases insulin. -- jamie ) "There's a seeker born every minute." |

I don't have any references, other than common knowledge that non-starchy vegetables have a lot of vitamins that you need. Oh, and fiber. Spinach is a great one. I actually have to be careful with my spinach consumption, not because of the carbs, but because sometimes I get too much fiber, if ya know what I mean. -- Michelle Levin http://www.mindspring.com/~lunachick I have only 3 flaws.

When Lance Armstrong recommends a low carb diet I'll believe it. Your
body can be forced to do lots of crazy things--not all that are good for you. They need to give Lance Armstrong a cameo in X3; damn guy's a mutant :-) Who the hell goes through chemo and is *stronger* for the experience? Watch out for the American cliche of, that which is easy and presently good must necessarily be dangerous and long-term painful. --Dan |

I guess that makes sense, if you are an endurance athlete. Lance Armstrong demands more from his body in one day of training than I do in probably a month of workouts. I would imagine his carb and energy needs are quite a bit different from mine. carla |
