Here's an interesting example this morning.
I rode my road racer bicycle for 70 minutes from 4-5:10
pm then ate chinese that's often high in fat. My BG
before exercise was 298 mg/dl so I took 8U Humalog 40
minutes before starting exercise. The distance
travelled was 15 miles in the warm Florida sun so I
drank much water along the way. My BG was 81 mg/dl at
5:30 pm after the exercise period. Then we had the
chinese food about 6 pm.
hmmm... you took the 8U Humalog at 3:20pm with a 298 (at
about the same time?)
so... 81 two hours later... assuming you've got your
background insulin close to your normal basal needs (a BIG
assumption given your wild BG swings), the very recent
exercise) would mean your normal basal insulin is now too
high and then you took extra NPH which is still active, so
at 5:30pm you've got at least 3+ units of FAST insulin
active (above your basal needs) and excessive basal
insulin also
did you eat anything at 5:30pm?

At bedtime (12 am) lipids and BG were:
Total Chol 240 mg/dl HDL 41 mg/dl Triglycerides 349 mg/dl
BG 378 mg/dl (underdosed dinner for exercise effects)
I had a triglyceride target of 100 mg/dl and have
determined trigs fall at 75 mg/dl/NPH Unit
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

i wouldn't call a bedtime BG of 378 good. i hope it's an
exception for this example
Hi Bill,
Just want to mention that catecholamines (adrenaline,
noradrenaline) and cortisol (stress hormone) were still high
post exercise as I couldn't get to sleep at bedtime. These
tend to keep BG high and you have to suffer through their
effects since you could go low abruptly if they end
abruptly. So the exercise training effect keeps my BG high
for about 12 hours. This is why the German MD Van Aiken
could get less sleep as an avid runner, for example. He
claimed 4 hours of sleep is all a runner needs. The training
effect kept him "hyped-up." I try to get 6-7 hours of sleep
no matter what. But sometimes the training effect keeps me
awake and the BG high. That's my metabolism. These
catecholamines also control blood pressure and I'm hoping I
can lower my BP with exercise. The idea is to get my
metabolism to right itself by using exercise medicinally.
This data is an early "snap-shot" of blood chemistry in this
rectification process.

some friendly comments/questions:
1. i wasn't aware that triglycerides can jump around like
your above example
if you have any refs on this, would you kindly provide
them
There are two energy substrates in the body: glucose and
triglycerides. When the body burns fats it's the
triglycerides, aka free fatty acids. My data shows
triglycerides can have extreme moves but much more slowly
than blood glucose. Muscles can burn triglycerides directly
but the brain can't, as an example. Ketones result when
triglycerides are burned. So high ketones do not necessarily
mean basal insulin is low. People on the Atkins diet could
have high ketones and normal insulinemia, as an example. The
only refs I have are basic physiology for a 12 hour fasting
measurement and not sports medicine related for more samples
over 24 hours.
Quoted message said:and how often do you see this kind of triglyceride
variation? (for yourself of course)
with what kind of frequency?
and/or are triglyceride jumps like this specific to
high levels of exercise?
If I eat pizza and look at trigs 5-6 hours post meal, they
are off the scale and I get HIGH on the meter (500 mg/dl max
assay range). If I fast for more than 12 hours,
triglycerides are low because the muscles are burning them.
There is an ebb and flow of fats (trigs) from the fat cells
to muscle and liver just like we see with glucose from the
liver to the muscles and brain. So there is no "frequency"
per se, since it depends on diet and exercise. Cortisol
causes the fats to be released from the fat cells into the
blood and when you get your "second wind" your muscles have
switched over from burning glucose to burning triglycerides.
Quoted message said:2. where did you come up with this? i.e.:
<"If blood ketones were >10.0 then basal insulin is
low.">
This is my observation where the fasting state maximum
ketones, with no basal insulinemia, are about ~17-20 mg/dl
on the Bioscanner 2000. If I'm burning triglycerides, a 12
mg/dl is not unusual but high nonetheless. A 6-7 mg/dl is
typical for me in the fasting state. A 3 mg/dl is typical as
Humalog peaks (1-2 hours post dose) in the fasting state. I
never see the low end of the ketone assay range of 2 mg/dl
(all time best is 2.6 mg/dl).
Quoted message said:3. given the amounts of insulin (that you mentioned
above), i find it hard to believe that another 5U of
"human"-R at midnight would have gotten that 319 rising
BG down to 100
I depends on the training effect, glycogen rebuilding,
stress like my wife bugging me, etc. So a broad brush stroke
of "I find it hard to believe" just tells me that you've
never experienced the training effect. You should exercise
alittle more and see what happens.
Quoted message said:4. i personally think you should use an insulin pump for
the next 2 years. that way you'll get a real clue about
what your basal needs really are (and how much yours
really do or don't fluctuate)
I'm not willing to use a pump. My last HbA1c was 6.6% with
the A1cNow about a month ago so I'm a happy camper. I
currently have to go to the lab before my next vist with the
Doc (I haven't made an appointment yet) and this is why I'm
looking at lipids in detail.
Quoted message said:5. i also suspect that you've got a lot of room for
improvement of your BG management. which is why i
suggested that you give serious thought to using an
insulin pump. trust me, you'll be in pig heaven (given
your love of high tech gadgets)
I'm sure I'll like the technology of the pump. But I'm a
happy camper with my current low tech method. If my HbA1c
was >8% (ref <6.1% normal), I'd consider it.
Quoted message said:6. oh, and one other thing... what little i know about
cholesterol/HDL/LDL is that the ratios are what's
important. 240:41 = 5.85, and
219:39 = 5.6
assuming your home meter numbers are accurate, both
ratios are high and might merit attention
Agreed. But exercise should move HDL up to 55-60 mg/dl. I
had these kind of numbers before I hurt my knee running a
decade ago. My Total Cholesterol target is <200 mg/dl and
HDL is >55 mg/dl with training. This will give me a
200/55=3.6 CVD risk factor (<5 is good for males, looking
for ref on this). Training should also lower LDL thereby
moving total cholesterol lower. The lowest total cholestrol
I've measured is 185 mg/dl. Calculated LDL averages ~140
mg/dl. So if I control trigs to 100 mg/dl I should see:
Total cholesterol ~= HDL+LDL+trig/5 = 40+140+20 = 200 mg/dl
!
And the Doc is a happy camper just by insulin control of
triglycerides alone. But exercise should help even more.
The trick is correctly dosing basal insulin to control trigs
but not have an impact on the liver to cause a drop in BG.
This permits some independence between basal insulin dosing
for triglycerides and the resultant impact on BG. The data
above, with high BG and low triglycerides, demonstrates that
this hypothesis is correct, i.e., I can dose basally for
triglycerides then add R to correct hyperglycemia. This is
the primary message in this data.
And I'll know in 2-3 months of training if I'm right
about lipids,
