Outline
  • History and Politics
  • Science of nutrition the evidence
  • Re-write the nutritional guidelines
  • Summary and action plan

4
Diabesity A Twin Epidemic
  • The spectrum of Insulin Resistance

5
Obesity Statistics
  • The progression of insulin resistance
  • 44 obese in 2030
  • 33 diabetic in 2050

Sources TFAH, OECD, WHO, CDC, ADA
6
Historical 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

7
USDA 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!

8
Macronutrient Content
  • More refined carbohydrates and less saturated fat
  • Total caloric intake increases from sugar
    consumption

February 6, 2004 / Vol. 53 / No. 4

Does 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!

10
Food 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

11
Food 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

12
Our 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

13
The 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

14
Evolution - Are You Kidding?
Nutrition changing humans in our lifetime!
The Food Revolution Andreas Eenfeldt, M.D.
15
Fat 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

16
Nutrition 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

17
Insulin 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

18
Insulin 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

19
Regulation of Food Intake
  • Leptin Insulin Amylin PP - Ghrelin - PYY -
    GLP-1
  • Resistance changes signaling
  • Promotes inflammation and mitochondrial
    dysfunction

21
Insulin 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

22
Insulin Resistance Treatment
  • The food is the medicine
  • Remove the optional fuel
  • Less dietary carbohydrates
  • Turn off the insulin switch
  • Control hunger and appetite

23
Insulin 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

24
Insulin 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

25
Eat 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

26
Comparing 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

27
Calories consumed equal, Atkins LCHF diet better
controls insulin, weight and appetite

Advanced 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
