6Historical Perspective
I am such a glutton and sloth
- Blame behavior and lifestyle choices
- Eating too much and exercising too little
- Obesity is caused by positive energy balance!
- A simple explanation
- Health insurance will not pay for treatment
- Its your fault, your problem, you fix it!
- The Lipid Hypotheses 1950s
- Avoid caloric dense fatty foods
7USDA Dietary Guidelines 1977-1980
Phillip Handler A vast nutritional experiment
- Less saturated fats, less calories
- More poly-unsaturated Vegetable oils
- More carbohydrates, starches, sugars
- More inexpensive food commodities
- Weak evidence, the wrong tools!
8Macronutrient Content
- More refined carbohydrates and less saturated fat
- Total caloric intake increases from sugar
consumption
-MMWR, Morbidity and Mortality Weekly Report,
February 6, 2004 / Vol. 53 / No. 4
9Does Saturated Fat Cause Heart Disease?
http//www.awlr.org
- Outcomes looking at MI, death from MI and stroke
- Observational - 16 studies - No!
- Observational - 8 studies - Yes but problematic!
- Observational - 2 meta analysis, 350,000 subjects
- No! - RCTs - Clinical trials - 2 well done - No!
- RCTs - Clinical trials - 3 meta analysis - No!
- RCTs - Clinical trials - 1 meta analysis - Yes
but problematic!
10Food Politics Agriculture
- Industrial revolution and the food commodities
- Corn, Wheat, Rice, Potatoes
- Sugars Cane, Beet, HFCS
- Soybean and industrial Vegetable oils
- Whole foods expensive Animals and other Plants
- Farming incentives, increase yields, GMOs
11Food Politics Manufacturing and ales
- To sell refined and processed foods for profit
- Food commodities are the raw materials
- Tasty and addicting foods, eat more
- Deceptive advertising Healthy foods
- Food lobbyists funding politicians
- Selling food not health
12Our Ancestors Before Agriculture
- Hunter gatherers and the Paleolithic era
- Whole foods, some carbs
- Animals including Fish, seasonal Veggies, Fruits
,Nuts and Roots - Use of fire
- Agriculture and the Neolithic era
- Cultivate Grains and domesticate Animals for
Dairy - Modern civilization changing nutrition
- For better or worse
13The Cost of Healthcare
- World leader in healthcare spending since 1980
- Treating chronic diseases
- Medicare and Medicaid industry guidelines
- Treatment of illness and disease only
- Obesity not a medical condition
- A reactive and costly approach to healthcare
- Preventive services task force 2012, counseling
- Treating obesity complications is profitable
14Evolution - Are You Kidding?
Nutrition changing humans in our lifetime!
The Food Revolution Andreas Eenfeldt, M.D.
15Fat Reform is Healthcare Reform
- Address obesity
- Save trillions treating complications
- Food industry regulation!
- Healthcare delivery
- Nutrition and center stage
- Re-define healthy nutrition
- Re-educate
- The perils of dietary carbohydrates
- In defense of dietary fat
16Nutrition and Metabolism 101
- Food metabolism
- All macronutrients are not created equal
- Carbohydrates are fattening and inflammatory
- Fats and proteins
- Obesity is a chronic metabolic disease
- Insulin resistance
- Inflammation
17Insulin and Insulin Receptors
- One of several hormones
- Regulate energy and energy storage
- Dietary carbohydrates, the primary fuel
- Turn on the insulin switch
- Dietary proteins and fats, secondary fuels
- Minimal effect on insulin, essential
- Insulin receptors normal function
- Cells, muscle, tissue absorb energy and nutrients
- Excess food energy converted to fat and stored
- Normally insulin will suppress appetite
- ? insulin promotes the release of stored energy
- Basic physiology
18Insulin Resistance
- Years of carbohydrate overload
- More insulin is required
- Excess energy, stored as body fat
- Receptors become strained and resistant
- Beta cells strained, abnormal response
- A disease of insulin overload
- Insulin resistance makes us hungry
- Fat cells literally starve lean body tissues
- Hypothalamus, Nucleus Accumbens
- Eventual loss of central signals
19Regulation of Food Intake
- Leptin Insulin Amylin PP - Ghrelin - PYY -
GLP-1 - Resistance changes signaling
- Promotes inflammation and mitochondrial
dysfunction
20Inflammation and Adiposity
Inflammation
Dyslipidemia
Premature Ageing
? Lipoprotein lipase
Hypertension
? Angiotensinogen
? IL-6
? Insulin
? CRP
? FFA
Liver Gut
Insulin Resistance
? IGF-1
? Resistin
? TNFa
? Leptin
Type II Diabetes
Cancer
? Adipsin(Complement D)
? Lactate
? Plasminogenactivator inhibitor-1
? Adiponectin
Atherosclerosis
Dementia
Thrombosis
Fertility

21Insulin Resistance Evaluation
Overweight
Obesity
Pre-diabetes (Metabolic Syndrome)
Type II Diabetes
- Anthropometric measurements
- Medical and family history, physical
- 2hr OGT, GTT
- Metabolic markers of inflammation
- HgA1c, c-peptide, Insulin, CRP, Thyroid, etc
- Cholesterol testing as a marker for
atherosclerosis
22Insulin Resistance Treatment
- The food is the medicine
- Remove the optional fuel
- Less dietary carbohydrates
- Turn off the insulin switch
- Control hunger and appetite
23Insulin Resistance Treatment
- Dietary proteins
- Essential, healthy
- Dietary fats and cholesterol
- Essential, healthy
- Caloric dense and filling
- NOT inflammatory or atherogenic
- One exception
- Carbs and fats together
- Standard American diet (SAD)
- Carbs are the catalyst

24Insulin Resistance Treatment
- Medication
- Physiologic drugs
- Metformin, Byetta, Victoza, Bydureon, Symlin
- Rx appetite suppressants
- New and future drugs
- OTC market
- Treat co-morbidities
- Nutrition center stage
- Gastric bypass surgery

25Eat Real foods
- Focus on the carbohydrate content of food
- Avoid high glycemic foods, processed foods
- Eat low glycemic foods, whole and unprocessed
- Healthy natural fats
- Butter, Animal fat, Coconut oil, Olive oil,
Avocado, Fish oil - Low-Carb High Fat (LCHF), Ancestral diets
- Control of appetite and promote weight loss
- Enhanced fat burning during exercise
- Quantity, calories and portions not the focus
26Comparing Diets Head to Head
- Compare the macronutrient content
- of calories from carbs, protein and fat
- Very low fat lt10, high carb, low calorie
- Very low carb lt10, high fat, LCHF, 1860s
- LCHF vs. Ancestral diets
- Food quality important
- What diets are healthy and safe?
- Low carb high fat (LCHF) diets improve health!
- Greater weight loss, improved lipids and blood
sugar - Dozens of RCTs, Stanford 2007, Duke 2004, Penn
2003, 2011 - Meta analysis , Santos 2012
27Calories consumed equal, Atkins LCHF diet better
controls insulin, weight and appetite
28(No Transcript)
29Lipid profile improved on Atkins LCHF
30Advanced Lipids and LCHF Diets
- Favorable LDL subclasses or particle sizes
- Triglycerides decrease, healthy HDL-C increases
- Other markers
- Apo-B, LDL particles
- Lpa, genetic markers
- Advanced labs
- Berkeley Heart Lab
- NMR Liposcience
- VAP Cholesterol
Effects of LCHF diet on emerging plasma markers,
