106 year old [(was Beets and Sweet Potatoes)

[Guest guest]

JW: Not sure how this relates to the topic but good for her. Is she healthy, coherent and still mobile? Has she related any wisdom concerning her longevity?

Thing is, we have a 106 yo lady in our town of 23K.

Thanks.

Re: [ ] Re: Beets and Sweet Potatoes

Thanks. I understand the process of metabolism.

My point remains. No one on CR is eating the equivalent of a glucose drip even if eating 5 or 6 meals. So to some degree everyone on CR is doing 1, 2,3 or 5 meals and ging through the process you describe. Maybe the 5 meal at a lower rate but still ging through it.

In your example the fat stored would be very temporary though the way it was originally stated made it sound like it would be more permanent

So again my question remains.

You also did not address the protein insulin connection

Jeff,

You ask " Where would the extra glucose come from? "

With a USDA diet of 15% protein, 55% carbohydrate, and 30% fat, the glucose comes, of course, from the carbohydrates. The Zone diet has 40% carbohydrates.

Since we eat usually three times per day, our bodies have to store the energy from the food to power our body when we are not eating. This is done by converting the sugars to glycogen or fat.

The body has a limited capacity for storing glycogen (http://en.wikipedia.org/wiki/Glycogen): " (100†" 120 g in an adult) soon after a meal "

The rest of the carbohydrate has to be stored as fat through Lipogenesis (http://en.wikipedia.org/wiki/Lipogenesis)

Eating is not like being on a glucose drip in a hospital. On a glucose drip, the amount of glucose administered corresponds to what is being burned from minute-to-minute, so it is not stored as fat.

Also, someone on negative energy balance will be losing weight and, in this case, the carbohydrates are not stored as fat, but rather the body fat is consumed to meet the metabolic requirements through lipolysis and gluconeogenesis.

But anybody on a steady state (steady weight maintenance, CR or no CR) who eats a meal will have a postprandial glucose spike that stimulates insulin production and lipogenesis. The only way to avoid this is to be on a glucose drip instead of eating real meals.

We eat a meal. Glucose goes up. It is stored as fat. We get hungry. The fat is burned. We eat again and the cycle is repeated until we die.

She appears coherent but so does my demented sis-in-law.

This adds to the other 6 centi's, at least, in a town of 23k.

As far as topic, I think Jeff has a point that many did not need "CR" to live longer, but that pre-supposes the centi's did not go thru times of low food.

Sweet potatoes are very easy to grow compared to grains, fruit trees, nut trees. So I regard those as a unique food in our past as well as peanuts.

Put the items all together does not effect our CR technique but it certainly is hard to explain or do unless we accept certain things like Americans eat too much, and we do not digest all of it, and we don't necessarily get unhealthy, as in diabetes, as the BMI studies indicate.

I have a 60 yo neighbor that went in for an infection at 385 #, and came out 60 # lighter after 3 days.

Of course she shouldn't have gotten that weight but she's not dead at 64 BMI.

The conclusions we draw, ignoring other factors, like osteo, suggesting large people should diet, I question.

I understand how diabetes should be treated - it can be "cured" by reducing intake - my other sis-in-law did that since 1979.

It is recognizing that individuals have diff pancreases and can tolerate extra weight without diabetes.

See, I am biased by my wife's and my higher than the nadir BMI, but i also see the risk of cardio is only 20% maybe.

I gain weight easily with extra protein, ie, higher than 56 grams, so I personally set that as MY limit .

The frustration is not having precise data for exercise req'ts, nor exact food properties, without which I cannot make exact statements.

I can only say eat as little as possible. I hold my weight with as little as 1500 kcals.

The 106 gal is about 180#. Re: [ ] Re: Beets and Sweet Potatoes Thanks. I understand the process of metabolism.My point remains.
