the Metabolic Syndrome." Metabolic Syndrome and Related Disorders 2(3): 180-186.
Methods
Outpatient clinical setting
Low fat diet + phen/fen (n=64)
Carbohydrate restricted diet (n=57)
Diet prescription was written.
20 grams carbohydrate/day until weight loss goal
obtained or patient willing to slow weight loss.
Both groups routinely monitored with office
visits and blood work.
Parameters Followed
Vital Signs; Blood Pressure, TPR, Weight.
Initially used caliper measurements of Body Fat
(Phen-fen). Low CHO patients followed with bioelectric impedance body composition scale.
Obtained CBC, fasting lipids, thyroid studies,
chemistry panel, C-peptide and UA.
Now also obtain hs-CRP, 24 hr urine for creatinine
clearance and microalbumin followed on all
diabetic patients. Labs repeated at ~3 mon.
intervals until stable weight –then at least yearly.

News Flash
Not all weight loss is the same in terms of
metabolic state.
Metabolic outcomes are different based on the
fuel source ( fat or carbohydrates)
What Can You Impact?
• Any condition related to hyperinsulinemia:
• CAD, prediabetes, metabolic syndrome, Type 2 diabetes
mellitus, hypertension, hyperlipidemia, dyslipidemia
including high triglycerides and low HDL, proteinuria due
to metabolic syndrome, obesity, acanthosis nigricans
• Central nervous system irritability such as seizures and
migraines
• Ovarian dysfunction due to hyperinsulinemia manifested
as polycystic ovary syndrome, irregular menses,
anovulation, irregular ovulation, facial hirsuitism
• GERD
• Sleep apnea, Pickwician syndrome
• Gestational diabetes, pre-eclampsia
• Osteoarthritis
• Inflammation
• Some Psychiatric conditions
Diseases of Civilization
Elevated carbohydrate intake (different
tolerance from one individual to another)
causes chronically high levels of insulin and
other inflammatory mediators.
These are the drivers of the diseases of
civilization-hypertension, metabolic
syndrome, prediabetes, diabetes and excess
fat mass gain.
Mitochondrial Energy Production
This is the key to life.
No mitochondrial energy production=death
No mechanic, no oil changes, only on-site
repair and oxidation must continue at all
times.
That’s a challenge-and nutrition is the key.
Mitochondrial Fuel Source
Mitochondrial fuel source is linked to
oxidative stress
Oxidative stress is linked to tissue damage
Mitochondrial enzymes adjust to fuel source
Constant mitochondrial energy production
without oxidative damage is the goal.
Is Adiposity the problem?
Sunburn is the best analogy
Genetic predisposition and environmental
exposure combine to cause damage.
Adiposity is a marker for hyperinsulinemia.
Excess adipose tissue is part of the pathologic
process of insulin resistance and
hyperinsulinemia
Two Approaches to Understanding
Human Metabolism
Classic
•
All calories have equal value,
regardless of source
• Importance of each
macronutrient tied to caloric
density
• Weight gain when energy intake
exceeds energy expenditure
• Lose weight by reducing caloric
intake and/or increasing caloric
expenditure
Hormonal
•
Increased carbohydrate intake
increases insulin production and
decreases lypolysis (fat-burning)
• Macronutrients control metabolic
hormone production, which
controls storage metabolism.
• High carbohydrate consumption
leads to hyperinsulinemia, which
leads to obesity and Metabolic
Syndrome
Hormones
Insulin
Glucagon
Incretins
Epinephrine
Norepinephrine
Cortisol
Sex Steroids
Branched chain amino acids
IL-6
Dietary Carbohydrates
Visceral Adiposity
Dr. Eric Freedland proposed the concept of the “critical
visceral adipose threshold”-the amount of visceral fat storage that
an individual could gain after which metabolic obesity ensued.
This hypothesis, in conjunction with individual tissue levels of
insulin resistance, may explain why one person is obese to the eye
but has fewer metabolic abnormalities while an apparently thin
individual is metabolically at risk.
Freedland, E. S. (2004). "Role of a critical visceral adipose tissue threshold
(CVATT) in metabolic syndrome: implications for controlling dietary
carbohydrates: a review." Nutr Metab (Lond) 1(1): 12.
Physiology of Obesity Treatment
Obesity is excessive adipose tissue (fat)
“Excess” is defined by metabolic and functional
parameters
The goal is to mobilize, or “burn fat”
To accomplish this goal, a change from “glucose
burning” to “fat burning” is needed
Fat Metabolism and Insulin
The hormonal milieu needs to be appropriate for “fat
burning”
The effect of insulin to facilitate glucose uptake is
linked to fat synthesis
“Fat burning” is inhibited by insulin, so insulin levels
need to be around basal levels
Insulin levels can be lowered by:
Increasing energy expenditure
Reducing carbohydrate intake
Insulin Promotes Fat Synthesis
Glucagon Promotes Fat Burning
Fatty acid
synthase
citrate
TCA cycle
mitochondria
Triglycerides
Malonyl CoA
ACCb
Glucose abundant-TCA
producing citrate via
acetyl CoA and
oxaloacetate. Insulin
increases availability of
TCA intermediates via
enzyme regulation
cytosol
CPT I
Acetyl CoA carboxylase
(ACCb ) is activated by
citrate and insulin, inhibited
by glucagon.
Fatty acid synthase inhibited
by glucagon
Intracellular and
intravascular
CPT I (Carnitine
palmitoyltransferase I)
moves long chain fatty acyl
CoA groups into the
mitochondria for oxidation.
Inhibited by malonyl CoA.
Fuel Sources: Fatty acids, ketones, glucose
Fatty acids can be utilized by most tissues for energy.
Ketone bodies are generated by the liver from fatty acid
oxidation. Ketones can be utilized by all cells except
glucose obligate cells and liver.
Glucose is synthesized by the liver and renal medulla from
amino acid precursors (gluconeogenesis). Cells without
mitochondria (erythrocytes, cornea, lens, retina) and cells
in low oxygen tension conditions (renal medulla) are
obligate glucose users.
Fatty Acids
Fatty acids are the main cellular fuel for all non-obligate
glucose using cells
Preferred fuel of the myocyte
A large pool of fatty acids are circulating on albumin at
any given time
There is nearly unlimited storage potential as
triglyceride in adipose tissue
Ketone bodies
Ketone bodies are molecules that deliver energy
(acetoacetate, acetone, b-hydroxybutyrate)

Glucose
Can come from diet, but also from internal sources
Excess is stored as glycogen in limited amounts, or as
triglyceride
Protein (amino acids) used by liver and kidney to produce
glucose (gluconeogenesis) and glycogen (glycogenesis)
Under mixed diet conditions, CNS use of glucose can be as high
as 120 grams/day
However, daily glucose use is only about 30 grams/day when
adapted to fat burning state (when fatty acids and ketones are
available for muscle and CNS use)
This 30 grams of glucose is easily supplied by endogenous
sources
Caloric Content of Food
A Calorie (kcal) is the amount of heat required to raise the temperature
of 1 kg of water by 1 degree Celsius
Foods can be oxidized to release energy, and the estimated caloric
values using bomb calorimetry are:
Triglyceride: 9.461 kcal per gm…… 9 kcal
Protein: 4.442 kcal per gm………… 4 kcal
Carbohydrate: 4.183 kcal per gm... 4 kcal
Alcohol: 7 kcal per gram……………7 kcal
Ketones: 4.5 cal per gram………….4 kcal
The actual caloric value will depend upon what oxidation pathway is
used, whether the energy has been stored, etc.
Glycogen is stored with water 1:3, so 1 gram of glycogen leads to 4
Oh, Those Free Radicals
• The effect of burning glucose as fast as
•
•
possible overwhelms the mitochondrial
electron transport chain and generates
increased numbers of free radicals.
Free radicals cause tissue damage.
Control glucose/insulin metabolism=control
free radical formation=control tissue
destruction.

Free Radical Management Plan
“Finally there are broad therapeutic implications from
the ability of ketone body metabolism to oxidize the
mitochondrial co-enzyme Q couple. The major source
of mitochondrial free radical generation is Q
semiquinone. The semiquinone of Q, the half-reduced
form, spontaneously reacts with O2 to form free
radicals. Oxidation of the Q couple reduces the
amount of the semiquinone form and thus would be
expected to decrease O2- production.” 1

conditions: ketosis, ketogenic diet, redox states, insulin resistance, and mitochondrial metabolism.

Mitochondrial Ketone Metabolism
Vacuums Free Radicals
In addition, the metabolism of ketones causes a reduction of the
cytosolic free {NAD+}/{NADH} couple which is in near
equilibrium with the glutathione couple. Reduced glutathione
is the final reductant responsible for the destruction of H2O2.

Ketones Improve Myocardial
Function
“How ketone bodies could improve the hydraulic
efficiency of heart by 28% could not be explained
by the changes in the glycolytic pathway alone,
but rather by the changes that were induced in
mitochondrial ATP production by ketone body
metabolism.”

Ketotic Benefits
Chronic adaptation to fat as primary energy
source may offer benefits such as improved
cerebral function (treatment of seizures),
improved mitochondrial ATP production,
decreased oxidative stress and protection of
glycogen stores during exercise.

Data are means (SE). Areas under the curve for insulin was different for each
diet (P 0.001). Glucose area under the curve was lower in response to the
low-carbohydrate diet (P 0.001 vs. other diets).
Bisschop et al. J Clin Endocrinol Metab;2003:88:3801–3805.
Eating Fat Equals Fasting
The importance of either carbohydrate or energy restriction in initiating the
metabolic response to fasting was studied in five normal volunteers. The
subjects participated in two study protocols in a randomized crossover fashion.
In one study the subjects fasted for 84 h (control study), and in the other a
lipid emulsion was infused daily to meet resting energy requirements during
the 84-h oral fast (lipid study). Glycerol and palmitic acid rates of appearance
in plasma were determined by infusing [2H5]glycerol and [1-13C]palmitic
acid, respectively, after 12 and 84 h of oral fasting. Changes in plasma glucose,
free fatty acids, ketone bodies, insulin, and epinephrine concentrations during
fasting were the same in both the control and lipid studies. Glycerol and
palmitic acid rates of appearance increased by 1.63 +/- 0.42 and 1.41 +/- 0.46
mumol.kg-1.min-1, respectively, during fasting in the control study and by
1.35 +/- 0.41 and 1.43 +/- 0.44 mumol.kg-1.min-1, respectively, in the lipid
study. These results demonstrate that restriction of dietary carbohydrate, not
the general absence of energy intake itself, is responsible for initiating the
metabolic response to short-term fasting.
Klein, S. and R. R. Wolfe (1992). "Carbohydrate restriction regulates the adaptive
response to fasting." Am J Physiol 262(5 Pt 1): E631-6.
The New Paradigm
Food can exert hormonal type influence on
metabolic pathways
Fat is not the problem
The changes caused by excess dietary
carbohydrate intake result in a shift in
metabolic pathways (characterized by
elevated insulin levels) which increase
inflammation and tissue damage.

Current Testing Misses the Problem

Insulin resistance, hyperglycemia, hyperinsulinemia, hyperlipidemia
and oxidative stress are risk factors related to cardiovascular diseases
including congestive heart failure, myocardial infarction, ventricular
hypertrophy, endothelial nitric oxide impairment in systemic blood
vessels and the heart, atherosclerosis, and hypercoagulability of blood.
The traditional focus on insulin sensitivity and blood levels of markers
of risk determined in the fasted state is inconsistent with the large
volume of recent data that indicates that the metabolic defect in the
pre-diabetic and diabetic condition relates more strongly to
postprandial deficiency than to the fasting state. Risk factors for
adverse cardiovascular events can be detected in the pre-diabetic
insulin-resistant subject based upon the metabolic response to a test
meal even in the absence of altered fasting parameters.
Haffner, S. M., M. P. Stern, et al. (1990). "Cardiovascular risk factors in confirmed
prediabetic individuals. Does the clock for coronary heart disease start ticking before the
onset of clinical diabetes?" Jama 263(21): 2893-8.
Patients who fall outside of the
existing paradigm
•
Metabolically obese normal weight
patients share the CV risk factors of their
obese neighbors, without the external
marker of obesity to alert their physicians
that preventative treatment is needed.
Looking for the Wrong Factors?
12% of patients with MI did not have
traditional risk factors.
Body, R., G. McDowell, et al. (2008). "Do risk factors for chronic coronary heart disease
help diagnose acute myocardial infarction in the Emergency Department?" Resuscitation
79(1): 41-5.
Risk is related to metabolic state
When subjects with impaired glucose tolerance at baseline (n
= 106) were eliminated, the more atherogenic pattern of
cardiovascular risk factors was still evident (and
statistically significant) among initially normoglycemic
prediabetic subjects. These results indicate that
prediabetic subjects have an atherogenic pattern of risk
factors (possibly caused by obesity, hyperglycemia, and
especially hyperinsulinemia), which may be present for
many years and may contribute to the risk of
macrovascular disease as much as the duration of
clinical diabetes itself.

cardiovascular risk." Ther Clin Risk Manag 3(5): 761-70.

Renal Failure
Carbohydrate restricted, low available iron, polyphenol
enriched diet (CR-LIPE)
191 Type 2 DM patients
Randomized to CR-LIPE or standard protein restriction
Mean follow up interval 3.9 years (+/- 1.8 years)
Serum creatinine doubled in CR-LIPE (19 pts/21%) and in 31
controls (31%).
Renal replacement or death=18 pts on CR-LIPE (20%) and 31
controls (39%)

Renal Failure
“ In conclusion, CR-LIPE was 40-50% more
effective than standard protein restriction in
improving renal and overall survival rates.”

Remove The Emotional “Hit”
We have told patients with Metabolic Syndrome to
eat a diet that increased their tendency to store and
which triggered rebound and stress hormones.
We have accused them of non-compliance when the
outcome was due to our recommedation.
Societal message is that to need to eat is to be weak.
We have contributed to “learned helplessness”.
JUST STOP
No guilt for provider.
No guilt for patient.
Honor your body-eat to prevent hunger and
stress chemistry.
Exercise to enhance metabolic and body
chemistry function.
Empower control.
Long Term Data
Medical monitoring was provided to taper diabetic
and anti-hypertensive medication
Inclusion criteria: baseline and greater than 12
months weight and laboratory studies
106 patients identified
Mean duration of treatment and follow up was 765
days (365 days to 3777 days )
For the 17 Type 2 diabetics with initial HgbA1C
greater than 6.5 mg%, the mean HgbA1c
improved from 9.2% to 5.8% (p=0.001)
