Differentiating between types 1 and 2 are confusing to most people. One is either insulin or non-insulin dependent.

Sir,

I am now 71. I wish to be healthy, and to extend my useful lifetime through diet high in proteins and fats, and low in carbohydrates; and exercise.

The info taught in my semester of Nutriton in college was largely contrary to Dr Herman Taller MD "Calories Don't Count" published 1961, and the remarkably similar Dr Atkins Diet Revolution published much later.

your responce is a non sequitor that does not answer the question: In your opinion is the following information substantially correct?

page 22 Let's eat right to keep fit by Adelle Davis

a similar study was made at Harvard University by Dr Thorn and co-workers who determined blood sugar levels for six hours after meals high in carbohydrates.

A high-carbohydrate breakfast consisted of orange juice, bacon, toast, jelly, a packaged cereal and coffee, both with sugar and milk. The blood sugar rose rapidly but fell to an extremely low level, causing fatigue and inefficiency. A packaged cereal eaten only with whipping cream for the high-fat breakfast, after which the blood sugar inceased slightly, then remained at the fasting level throughout the morning.

The high protein meal consisted of skim milk, lean ground beef, and cottage cheese; the blood sugar rose to the high level of 120 milligrams and remained there throughout the entire following six hours.

To determine the effects of different types of food on energy production, metabolism tests were taken at fcrequent intervals. The metabolism, or energy production, increased only slightly after the meals high in fat or carbohydrate. After the high-protein meal, however , the metabolism rose more quickly than did the blood sugar and stayed high throughout the entire six hour study period.

p 23 sugar, cereals, hotcakes fruit, fruit juice quickly changes to sugar during digestion . in minutes blood sugar may increase from 80 to 155 milligrams ..stimulates pancreas to pour forth insulin; the insulin in turn causes the liver and muscles to withdraw sugar and store it as a form of sugar, or glycogen or change it into fat, thus preventing it being lost in urine. The tremendous amounts of sugar defeat the purpsoe for which sugar is needed -- to produce enegy efficiently. Too much sugar is withdrawn due to the oversupply of insulin; the result, ironically, is fatigue

p 24 in studies mentioned, efficiency for three hours was produced by only 22 grams or more of protein. Meals furnishing 55 grams protein sustained a high level of energy and a high metabolism for six hours afterward.


p35 "Let's eat right to keep fit" Adelle Davis

When you eat more protein than your body can use immediately, your liver withdraws amino acids from your blood and changes them temporarily into protein storage. As your cells use amino acids the supply is replenished from the breakdown of stored protein. As long as your diet is adeduate, the amount of amino acids in your blood is thereby kept relatively constant.

If you ignore your health to the extent of eating insufficient protein, the stored protein is quickly exhausted. From that time on, the less important body tissues are destroyed to free amino acids needed to rebuild more vital structures. Such a process can go on month after month, year after year. Your body continues to function after a fashion. Useen abnormalities set in because blood proteins, hormones, enzymes, and antibodies can no longer be formed in amounts needed. Muscles lose tone, wrinkles appear, aging creeps on , and you, my dear, are going to pot.

It is possible, though not probable, that you may eat more protein than your body needs. After the storage depots are filled, the leftover protein is changed by the liver into glucose and fat, the nitrogen being excreted in urine; the sugar and fat may be used immediately to produce energy or may be stored as fat. Proteins are also used to produce energy whenever too few other foods are eaten to produce calorie requirments.

Aren't you concerned about high fat/high protein diets also, as these carry their own risks.

True high carbohydrate diets; particularly those that induce a high insulineamic response carry their own risks (and there is only limited evidence of this). Research looking at the interaction between exercise and high carbohydrate diets has shown that exercise reduces risks through a number of mechanisms.

Even so, the recomendations for a healthy diet are far from high carbohydrate and far from 'Atkin's' type diets. Actualy somewhere in the middle.

Why don't you eat a 'normal' balanced diet instead of a high carbohydrate or high fat diet and avoid refined fats and sugars?

There are far more reliable sources of information out there other than the Atkins books!

If I correctly understand what I read in Vilhjalmuir Stafansson "Arctic Manual" the Eskimo living north of the Arctic Circle ate land and marine animals, fish and fats. They had no diabetes, tuberculosis, heart disease or dental decay.

sounds good to me

plese tell me the names of sources of information more reliable than Dr Atkins books.

They also didn't live as long, had a different lifestyle, cooked foods differently, didn't have processed foods, were more active, come from a different gene pool, etc.

So if they didn't die from these diseases what did they die from?

Diabetes (type 2) and Heart Disease are generaly seen as 'older' peoples diseases as they take a long time to develop (although the incidence of T2 Diabetes in youngsters is increasing and fatty streaks have been found in the Aortas of 3 year olds).

This is hardly good evidence that this diet is good for you! Similar comments can be made about other less well developed countries where meat is hard to come by... I am sure that many have very low heart disease rates.



I might, are they intended as nutrition books?



The Atkins books are products and the science in them is always being questioned. There are many good textbooks on nutrition that explain the issues of high fat and high carb diets. IMO stay clear of 'fad' diet books.

I just did a simple search on amazon... Nutrition Textbooks

If high fat or high carb or high protein diets all have inherent risks, what are we meant to eat? Surely there is some balance to be found!!!

Nutritional study is like a lavalamp, constantly changing. What is currrent information on one day is obsolete the next. Just find the diet and exercise plan that works for you personally.

I disagree; there is just a whole que of band wagons for people to jump on and off.
