Thanks Terry your comments are helpfully and right on in my mind,
however I would like add a note that Adkins diet and several others like
it do not advocate the total lack of carbohydrates or severe
elimination. They advocate just what you have said here GOOD Carbs are
the KEY, It is a three phase affair: {vegetarians can also use this
diet using tofu but remember protein and oils are key}
1) Weight loss phase 1 - Induction 2 weeks severe carb reduction,
(includes high water intake for liver and kidney functions) include
fish, Lean beef, cheese, flax seed oil. (I would actually enjoy fish oil
and got a nice energy buzz from it) (stay away from Pig fat bacons etc
[additives]) (healthy stuff is key here)
2) Weight loss phase 2 - Introduction of some very good carb sources but
go slow - just watch the scale, till you reach a good healthy weight.
EXERCISE is INCLUDED.
3) Life time diet phase 3 - No sugars ever. stevia or Xylitol, (STAY
AWAY FROM ARTIFICIAL S) Good natural food sources high in fiber
including breads and fruits as much as you can handle based on how you
exercise and how you live. MAKE EXERCISE A DAILY PART OF LIFE and use
your scale to monitor the way how much fruit etc you eat. {Dont eat
meat and oils with high carbs together -6 hrs apart - this works for me
don't know why}
Natural local grown foods are best - complex carbohydrates only. You
will do the world a favor because you won't be buying the over packaged
super garbage foods that puts the wrapper in the landfills and the eater
in the hospital.
One last note: the Eskimos have records (according to James Michner in
his credits for the book _Alaska_) of elders living past 100 years,
their diet was full of good meat, good fat, some good carbs (harvested
from the sea) and good water they existed this way for centuries until
they were introduced to a civilized diet.
Thanks,
Jim

Re: [Biofuel] atkins
Terry, Read the book - you too are seriously misinformed. If you understood the diet fully and followed the program correctly you would see that fruits, vegetables, vitamins, protien, excercise, etc, etc, etc are not only mentioned but almost to ad nosium discussed, explained, and litterally spelled out for even the most simple of simpletons.

My good bio-friends, I feel I must speak out in defence of Dr. Atkins. It so obvious, by the tone of the comments here, that very, very few have actually read his book.

We have been busy with our new life style for 3 months now and we are almost to our goal weights and are currently in phase 2. I hvae only 1 kilo to go and then on to phase 3. My colestorol from 9 down to 7.5. Yes that was high and it can be even lower but apparently I have been blessed with the heart and collestorol troubles from my mother and her father and his father. thus, it's genetic.

Re: [Biofuel] atkins
Ken, No one shall eve hear me say that Atkins the be all, end all way of life. Everyone should find what they are comfortable with and what they can personnally manage. I think my biggest challenge with some of the comments that are flying around here is that it is mostly hear-say. Before I jumped onto this band-wagon I had a high colestorol level for someone that is only 37. My doctor said literally that I had a level compared to some of his 80 year old patients. This being a blow to my ego because I am not and have never been over-weight. My BMI has always been in the green. Since I began Atkins I can walk my 5 km per day much easier. Normally I'd come home, have to sit down and have to rest for a few minutes. Nowadays it's grab a glass of water and hit the showers and off the the next event. I have always exercised and still do. I walk my 5km, 4 to 5 times per week - and I have been doing that for years. I appreciate your life-style and it is very familiar to me. I have enjoyed life on a very similar diet to yours until 3-1/2 months ago and felt fine. Now I feel great and my blood-pressure, colestorol, and heart-rate are lower. For me this is the ticket. For you, as for many other people, is what you are doing great for you. Stick to a winning team - what ever that may be.

However, I don't eat ANY refined carbs (white flour or white sugar). I also feel wonderful but, I don't think that it has anything to do with my diet. But, if I miss exercise for a couple of days, I can definitely feel the difference. I can also tell how much better I feel the day after vigorous exercise. Feeling energetic is more about metabolism than food inputs unless you aren't eating enough and your metabolism is jump-started by exercise. In response to your comparison of atkins versus low-fat diets and fullness. There have been many, many studies that indicate that high-fat foods generally have a much lower fullness-factor or satiating affect compared to whole grains/beans. Unless the low-fatters are eating poor quality food such as white bread and iceburg lettuce, there is no reason for them to be walking around hungry. I am very rarely hungry, unless I haven't eaten in a reasonable time. Then again, I tend to eat my fair share of granola and oatmeal both of which are VERY filling. check out your favorite foods at www.nutritiondata.com.

Terry's mechanic should be a little more specific with him, rather than issuing a sweeping and perhaps unsupported statement. Perhaps I can shed some light on this topic, as I am an engineer at Cummins Inc, and work in Fuel System Development. Officially, Cummins supports Biodiesel blends up to B5 or 5% Biodiesel.There are several concerns the company has with higher ratio blends. There are three major areas of concerns that the company has. These are mostlycommercial concerns which will be evident as I explain them any of which an individual could deal with by being aware and careful about what they put into their tank. First, while biodiesel is touted as being cleaner, there are some caveats.While the particulate emissions (the ones you can see) are considerablyimproved with biodiesel, the NOx emmission will increase and the higher the biodiesel ratio the higher the NOx increases. Up to B5 the increase will not likely move the engine's NOx emissions beyond the federal limit, but B20 and higher will likely move the NOx emissions outside of the box. Since the US tends to hold the manufacturers repsonsible for the emissions of the engines instead of the users the company must maintain a strict policy against recommending or accepting fuels that will violate the regulations. Second, biodiesel has a lower heating value than Petro diesel, therefore the higher the biodiesel blend the lower the available power from the engine.Most vehicles with B5.9 diesel are substantially overpowered so the driver may not notice the 2% loss of power with a B5 blend, but it will become more noticeable as the ratio is increased. As I said many of the vehicles, especially pickups are overpowered for the job they do, so you it wouldlikely not be bothered unless you are street racing or pulling a large (heavy) trailer through the mountains. But once again as a company Cummins is in the position that if the sell a 305 Hp engine and the customers tend to expect to get 305 Hp regardless of what fuel they chose to put in the tank. The third and more serious concern for us homegrown biodieselers, in my opinion, is water. Most tanks collect water, many vehicles are equippedwith water separation filters to protect the fuel system components. The problem is the biodiesel has a higher affinity for water than petrol diesel, so the biodiesel is going to carry the water out of the tank. Furthermore,the water separators that are normally used will NOT extract the water from biodiesel so the water gets carried into the fuel system. Most modern fuel systems are very sensitive to water. The engine will run initially but the internal fuel system components will quickly corrode which will lead to a fuel system failure, and usually an expensive one. The company is also concerned about the quality of the biodiesel coming on the market. They have a wide variety from some very high quality to some very poor quality and currently there are no recognized quality standardthat the commercial producers are going by. There are other concerns with blending biodiesel with the coming Ultra Low Sulfur Diesel (ULSD). It has a few challenges to overcome but I will not go into the details here. With all that said, my personal observation (not the view of Cummins) is that if you pay attention to what you are putting in your tank qaulity wise. You make sure that it is dry. Then you should not have any problems with the fuel system of the age mentioned. The timing does not need to be changed in order for the engine run,
