Metabolic Syndrome / Obesity
POTENTIAL ROOT CAUSE #1:

SUGAR

2013 Ivor Cummins BE(Chem) MIEI
Fructose Vs Glucose Sources

Sucrose (Table Sugar):
50%glucose / 50% fructose

High Fructose Corn Syrup (HFCS):
55% fructose / 45% glucose

Glucose-glucose-glucose......chains
So-called ”Simple Carb”, added sugar too though..

Fruit: 4% to 8% Fructose
(but with lots of Fibre & Good Stuff!)

Coup De Grace? 2013: The Rat Proxy…

“…this study aims to develop a rat model
which closely depicts MS in humans…”
“Replacing whole wheat with refined wheat flour in rat
chow in 60% fructose-fed Sprague-Dawley rats resulted
in:

hypertension (p 0.01)

hyperglycemia (p 0.03)

hyper-triglyceridemia (p 0.001)
HDL Reduction (p 0.002)

More Rat Tales….
In results published online Feb. 26 2010 by the journal Pharmacology,
Biochemistry and Behavior, the researchers from the Department of Psychology
and the Princeton Neuroscience Institute reported on two experiments
investigating the link between the consumption of high-fructose corn syrup and
obesity.
"When rats are drinking high-fructose corn syrup at levels well below those in
soda pop, they're becoming obese -- every single one, across the board. Even
when rats are fed a high-fat diet, you don't see this; they don't all gain extra
weight."
The second experiment -- the first long-term study of the effects of high-fructose
corn syrup consumption on obesity in lab animals -- monitored weight gain, body
fat and triglyceride levels in rats with access to high-fructose corn syrup over a
period of six months. “Compared to animals eating only rat chow, rats on a diet
rich in high-fructose corn syrup showed characteristic signs of a dangerous
condition known in humans as the metabolic syndrome, including abnormal
weight gain, significant increases in circulating triglycerides and augmented fat
deposition, especially visceral fat around the belly. Male rats in particular
ballooned in size: Animals with access to high-fructose corn syrup gained 48
percent more weight than those eating a normal diet.”

SUMMARY FINDINGS
•Excessive Dietary Sugar and simple carbs are the primary root
cause of the Metabolic Syndrome and associated “Diabesity”
Epidemic (i.e No Sugar, and stick to Vegetables only for your carb input)
•Excessive Sugar and simple carbs promote insulin response and
appetite dysfunction, creating multiple self-reinforcing loops
•Sugar / simple carbs are the primary development agent of Insulin
Resistance Syndrome through proven mechanisms, and are a
primary driver of Lipid Generation (“Bad Cholesterol”) and
eventual dyslipidemia
•The driven weight gain consists of adipose tissue (esp. Visceral)
which exacerbates Insulin Resistence, drives Leptin Resistance and
reinforces the disease process
•Natural Dietary Fat is NOT a core root cause of the metabolic
syndrome and associated disease/obesity – and it does NOT cause
“Bad Cholesterol” !!!! Time to end 40 years of Bad Science….

Current Working Thesis:
1. Excessive Dietary Sugar (directly ingested or in as found in most processed
food/drinks) is the 1st order primary root cause of the Metabolic Syndrome and
associated “Diabesity” Epidemic through the following elements:
1.1 Insulin Resistance is the driving force of appetite dysfunction, excessive fat storage and the constellation
of metabolic disease.
1.2 Sugar is the primary aggravator of Insulin Resistance through proven mechanisms, and is a direct driver
of Lipid Generation and eventual dyslipidemia (Serum Triglyceride, VLDL etc)
1.3 An elevated proportion of simple, high-glycemic carbohydrate in the diet (Glucose rapidly released by
Amylase, no fibre to attenuate), works in tandem with the simple sugars to promote Insulin Resistance.
1.3 Fructose is particularly pathogenic thru many pathways – lack of satiety signalling, promotion of Hepatic
fat generation and hepatic IR, lack of Ghrelin suppression, impact to Leptin levels, etc
1.4 The driven weight gain consists of adipose tissue (esp. Visceral) which is itself an organ, releasing body
toxic cytokines and hormones, exacerbating Insulin Resistence and accelerating the disease process

2. The disproportionate / non-linear rise of disease relative to the increase in sugar consumption can
be attributed to amongst other things:
2.1 Gestational Insulin Resistance and predisposition towards obesity in the next generation (2 nd order effect)
2.2 Co-incident lowered level of physical activity in society exacerbates the high sugar / simple carb damage

3. Dietary Fat is NOT a core root cause of the metabolic syndrome, but excess sugar / simple carbs
through the action of the insulin elevation will drive dietary fat into storage (obesity) and further
negative pathways will result as seen

"High triglycerides alone increased the risk of heart attack nearly three-fold.
And people with the highest ratio of triglycerides to HDL -- the "good"
cholesterol -- had 16 times the risk of heart attack as those with the lowest
ratio of triglycerides to HDL in the study of 340 heart attack patients and 340
of their healthy, same age counterparts.
The ratio of triglycerides to HDL was the strongest predictor of a heart attack,
even more accurate than the LDL/HDL ratio. (Harvard-lead study - Circulation
1997;96:2520-2525)."

  • 96. More Rat Tales…. In results published online Feb. 26 2010 by the journal Pharmacology, Biochemistry and Behavior, the researchers from the Department of Psychology and the Princeton Neuroscience Institute reported on two experiments investigating the link between the consumption of high-fructose corn syrup and obesity. "When rats are drinking high-fructose corn syrup at levels well below those in soda pop, they're becoming obese -- every single one, across the board. Even when rats are fed a high-fat diet, you don't see this; they don't all gain extra weight." The second experiment -- the first long-term study of the effects of high-fructose corn syrup consumption on obesity in lab animals -- monitored weight gain, body fat and triglyceride levels in rats with access to high-fructose corn syrup over a period of six months. “Compared to animals eating only rat chow, rats on a diet rich in high-fructose corn syrup showed characteristic signs of a dangerous condition known in humans as the metabolic syndrome, including abnormal weight gain, significant increases in circulating triglycerides and augmented fat deposition, especially visceral fat around the belly. Male rats in particular ballooned in size: Animals with access to high-fructose corn syrup gained 48 percent more weight than those eating a normal diet.” 2013 Ivor Cummins BE(Chem) MIEI

SUMMARY FINDINGS •Excessive Dietary Sugar and simple carbs are the primary root cause of the Metabolic Syndrome and associated “Diabesity” Epidemic (i.e No Sugar, and stick to Vegetables only for your carb input) •Excessive Sugar and simple carbs promote insulin response and appetite dysfunction, creating multiple self-reinforcing loops •Sugar / simple carbs are the primary development agent of Insulin Resistance Syndrome through proven mechanisms, and are a primary driver of Lipid Generation (“Bad Cholesterol”) and eventual dyslipidemia •The driven weight gain consists of adipose tissue (esp. Visceral) which exacerbates Insulin Resistence, drives Leptin Resistance and reinforces the disease process •Natural Dietary Fat is NOT a core root cause of the metabolic syndrome and associated disease/obesity – and it does NOT cause “Bad Cholesterol” !!!!

  • 118. Current Working Thesis: 1. Excessive Dietary Sugar (directly ingested or in as found in most processed food/drinks) is the 1st order primary root cause of the Metabolic Syndrome and associated “Diabesity” Epidemic through the following elements: 1.1 Insulin Resistance is the driving force of appetite dysfunction, excessive fat storage and the constellation of metabolic disease. 1.2 Sugar is the primary aggravator of Insulin Resistance through proven mechanisms, and is a direct driver of Lipid Generation and eventual dyslipidemia (Serum Triglyceride, VLDL etc) 1.3 An elevated proportion of simple, high-glycemic carbohydrate in the diet (Glucose rapidly released by Amylase, no fibre to attenuate), works in tandem with the simple sugars to promote Insulin Resistance. 1.3 Fructose is particularly pathogenic thru many pathways – lack of satiety signalling, promotion of Hepatic fat generation and hepatic IR, lack of Ghrelin suppression, impact to Leptin levels, etc 1.4 The driven weight gain consists of adipose tissue (esp. Visceral) which is itself an organ, releasing body toxic cytokines and hormones, exacerbating Insulin Resistence and accelerating the disease process 2. The disproportionate / non-linear rise of disease relative to the increase in sugar consumption can be attributed to amongst other things: 2.1 Gestational Insulin Resistance and predisposition towards obesity in the next generation (2 nd order effect) 2.2 Co-incident lowered level of physical activity in society exacerbates the high sugar / simple carb damage 3. Dietary Fat is NOT a core root cause of the metabolic syndrome, but excess sugar / simple carbs through the action of the insulin elevation will drive dietary fat into storage (obesity) and further negative pathways will result as seen 2013 Ivor Cummins BE(Chem) MIEI
