Possibly both. Exercise increases the body's nutritional requirements, and a

low-fat diet fails to satisfy them.

Hi Alecwood,

I am not a specialist in athletics, but have gone through years of

hypoglycemia and chronic fatigue. I used to write articles for a health

magazine and was associated with a lot of very talented alternative healers.

They were all convinced that any illness could be turned around by removing

the toxins (true) and and becoming vegetarian.

I went from vegetarian, to vegan, to raw food vegan (extreme), even into

macrobiotics. All of it made me so much worse.

Everyone's metabolism is different. Some people need more carbs and some

need more fats and protein.

I have found that I need high fat/protein. In the short amount of time I

have eating this way my CFS and other symptoms have improved. Today I

understand it is about managing blood insulin levels that helps so much, and

that is done with fats/protein.

Both, probably. The huge demands long distance running (or any other

extreme regimen of exercise) place on the body will only worsen the effects

of bad diet.

Here's what Dr. Ray Peat said in an interview with Shomon on

About.com. The full interview is available at

http://thyroid.about.com/gi/dynamic/offsite.htm?site=http://www.thyroid%2Dinfo.c\

om/articles/ray%2Dpeat.htm

>> Shomon: You feel that excessive aerobic exercise can be a cause of

>>hypothyroidism. Can you explain this further? How much is too much?

>>

>>Dr. Ray Peat: I'm not sure who introduced the term " aerobic " to describe

>>the state of anaerobic metabolism that develops during stressful

>>exercise, but it has had many harmful repercussions. In experiments, T3

>>production is stopped very quickly by even " sub-aerobic " exercise,

>>probably becaue of the combination of a decrease of blood glucose and an

>>increase in free fatty acids. In a healthy person, rest will tend to

>>restore the normal level of T3, but there is evidence that even very good

>>athletes remain in a hypothyroid state even at rest. A chronic increase

>>of lactic acid and cortisol indicates that something is wrong. The

>> " slender muscles " of endurance runners are signs of a catabolic state,

>>that has been demonstrated even in the heart muscle. A slow heart beat

>>very strongly suggests hypothyroidism. Hypothyroid people, who are likely

>>to produce lactic acid even at rest, are especially susceptible to the

>>harmful effects of " aerobic " exercise. The good effect some people feel

>>from exercise is probably the result of raising the body temperature; a

>>warm bath will do the same for people with low body temperature.

(T3 is the active form of thyroid hormone. The thyroid gland principally

produces T4, which circulates through the body being converted to T3 on

location as needed. Most thyroid supplements on the market are synthetic

T4, which is not actually exactly identical to human T4, and there have

been a series of scandals and law suits and recalls surrounding synthetic

T4 due to poor quality control, dosage variation, etc.)

As Dr. Marasco said, your cousin needs to lay off the running for a good

long time and change his diet radically to rebuild his system. I'm not so

sure his CFS and possible hypothyroidism will just disappear on their own

without further work, but it's certainly possible.

There's also a book he might want to check out, _Body, Mind and Sport_ by

Douillard. I think someone else on this list might have recommended

it, and it looked extremely interesting, so I bought a copy. I haven't

read it yet, so this isn't an endorsement, but it purports to tell readers

how to reduce the stress load -- and heart rate elevation -- from exercise

to improve fitness and performance.

,

Thanks for all of your past answers. You've been very

helpful.

I'm finding this topic to be quite interesting and

informative. Do you know of any other references to

aerobic exercise being a problem for overall health?

I want to go over this with a medical minded friend of

mine and I will need research, facts, studies, etc.

for him to change his mind. He is open minded, but

not without evidence. He still believes in carbo

loading also!

Also, I heard on a radio show last week that a study

was done at a major University that showed people on a

diet of high protein, and fat; low carbos- for only 4

weeks, showed a decrease in done density. Of course

the answer was a higher carbo diet to prevent this

from occuring.

Question- what is causing this decrease of bone

density and what can people on a restricted carbo diet

do to prevent this?
