When you say "cut carbs to 100 a day" - are you saying 100 grams of carbohydrate (400 kcal), or 100 kcalories from carbohydrate (25 grams)? Thanks |

It isn't really a matter of weight bearing vs non weight bearing. It is just a fact that it takes quite a while to burn a lb of body fat and that means a lot of miles. >You'll also need to do some intense rides each week. Don't >just go through the motions of pedaling. You're going to >need to do some hard riding. I would disagree depending on what you mean by "intense" rides. He could even lose weight by cruising at 12 mph on flat terrain, he would just have to spend hours doing it to burn up many calories. >All that may not be enough. Adding a cross-training >activity would help. I walk in the mornings and I do 15 >minutes of core strength exercises. You do enough cycling and you can burn up the calories and you don't need no stinkin cross-training. As I posted above, I burned off 10 lbs of fat in 14 days by doing a lot of cycling in the mountains and doing a sort of reverse Atkins diet - lots of carbs to replace glycogen, low fat and a little protein. Remember, quantity has a quality all its own. |

The beauty of an aerobelly is that it has no more frontal area at all, but stores additional inertia. On the flat, it requires a slight increase in effort to accelerate, but once going, you keep on going. This means that a gust of wind won't slow you down, or for that matter steady wind, as much as it would if you lopped off the aerobelly. The aerobelly is made for cruising. Downhill, it provides the gravity assist with no cost whatsoever. Aerodynamically, while it has no more frontal area, it does provide a better aerodynamic shape than a flat torso. If the rounded front-end wasn't more aerodynamic, autos would all look like this: http://www.sweptline.com/hist/big1_coe.jpg -- Rick Onanian |

The link between high insulin levels and cardiovascular disease (along with a whole host of other problems) is proven and the mechanisms are well understood.

A low-cal, high carb diets may lead to insulin resistance but that does "not" mean that a low-cal, balanced diet would. A balanced low-cal diet consists of 20% protein, 30% fat, and 50% carb calories and unless a person is already pre-disposed (hereditary or already partially insulin resistant) to diabeties this diet won't create a significant problem. Are you saying that nobody has ever lost weight on a low-cal diet once they became fat? > > Others have noted the possible increased risk for > cardiovascular disease from a low-carb diet.

While I agree with almost all of what you're saying, it is not exactly true that one you're fat, you can't lose weight by reducing calories. I've been a type 2 diabetic since age 23 (I'm 46 now) and I lost 100 lbs on a low fat diet with lots and lots of exercise (did I say lots & lots?). As a type 2, I was fully insulin resistant. Of course, all of that exercise and restricted eating worked to make me less and less insulin resistant over time, but I still lost easily when I was very large (we're talking 360 lbs here). So the point here is: it depends. A lot of people are as you describe, btw. :: :: Others have noted the possible increased risk for :: cardiovascular disease from a low-carb diet. That claim is nonsense, imo. The link between high insulin levels :: and cardiovascular disease (along with a whole host of :: other problems) is proven and the mechanisms are well :: understood.

Right! However, I'm not sure I believe the claims of the body robbing lean mass from the heart muscle. While I can see that under the most severe of conditions, why would the body rob from a vital organ when there are leg muscles, butt muscles, back muscles (most of the muscle mass on the body is in those locations) that have plenty of mass to pick from? The body is amazingly smart at protecting itself, so someone is going to have to provide me with a lot of reference material before I accept that notion so easily. |

See your doctor; people with moderate or severe hypothyroidism will not loose weight unless it is treated. Diagnosis is via a simple blood test and treatment is usually by a hormone suplement pill taken daily. IIRC, you mentioned carying the weight mainly around the waist. This is another hypothyroidism characteristic. I'm actually surprised that no one has suggested it already. Austin |
