DESCRIPTION

A brief outline of how inflammation is responsible for the obesity epidemic and the idea that reducing caloric intake to lose body fat and get healthier is flawed.

The “Calorie reduction as primary”

hypothesisJeff Lynch

What is the most basic principle of weight gain?

1st Law of Thermodynamics

ΔU = Q - W

The amount of energy stored within a system is equal to the amount of energy

put in minus the energy expended

Body Fat = Food eaten - Energy Expended

The facts of life

• Starting point

• You eat more and exercise less

• You put on fat

• As a result your metabolism becomes unhealthy

• Then you become ill (metabolic diseases)

And here’s what happens

• You eat more and exercise less

• You put on fat

• Your metabolism becomes unhealthy

• You become ill (metabolic diseases)

1st Law of Thermodynamics

ΔU = Q - WBody Fat = Food eaten - Energy Expended

• Q and W must be independent

• A calorie is a calorie:

• ΔU is unregulated

• Q and W are under conscious control

Then

• You eat too much and exercise too little

• You put on fat

• Your metabolism becomes unhealthy

• You become ill (metabolic diseases)

Metabolically healthy obese

• A healthy subset

– Similar metabolic health to lean people

– Around 6%

• We don’t know why they exist

– Fat distribution

– Genetics…?

• They still have higher mortality

The metabolically unhealthy non-obese

Fatty liver– Alcohol– NAFLD– Fructose (HFCS)

• Handled the same way as alcohol

• Genetics/Race– Lean Indian mean 3-4 time higher

incidence of NAFLD and inflammation

• Autoimmunity– Type 1.5 DM– ¼ lean diabetics produce the same

antibodies found in T1DM.

• Stress– Chronically elevated blood sugar

Clinically normal prediabetics

Beta cell dysfunction

– Stage 1: Compensation

– Stage 2: Stable increased blood glucose

– Stage 3: Unstable decompensation

– Stage 4: Type 2 Diabetes

– Stage 5: Type 1 diabetes

What is metabolic disease?

Symptoms

• Obesity

– Abdominal

• Insulin resistance

– High blood sugar

• Dyslipidemia

• Inflammation

– IDDM?

– NIDDM

If it isn’t caused by eating too much or exercising too little then what is the

cause?

Metabolic disease is an autoimmune, chronic inflammatory disorder involving a pathological

expression of the innate immune system

• Innate immune system

– Non specific first line of defence

• Inflammation

– Response of the IIS to infection and trauma.

• What causes it?

What causes it?

• Dietary toxins

• Environmental toxins

• Micronutrient deficiencies

• Chronic stress

• Altered gut microbiota

• Sedentary lifestyle

• Genetics

How inflammation causes metabolic diseases

• Inflammation precedes metabolic disease– 1/3 of Hep C patients get diabetes

– Rheumatoid arthritis sufferers are at higher risk

• Inflammatory proteins cause insulin resistance– Mice injected with inflammatory proteins develop

insulin resistance

– TNF-a causes insulin resistance

• Inflammation in the brain causes leptin resistance

• Inflammation in the gut leads to both leptin and insulin resistance

How metabolic diseases cause inflammation

• Fat tissue releases inflammatory cytokines

– Catabolic breakdown of fat

– Not been selected against

• Genetic up regulation of inflammatory pathways

– Macrophages increase in number

How metabolic diseases cause inflammation

• Fat tissue releases inflammatory cytokines

– Local catabolic breakdown of fat

– Not been selected against

• Genetic up regulation of inflammatory pathways

– Increased number of macrophages

Weight loss 101

A. Calorie Reduction

• Slower metabolic rate

• Increased hunger

• Reduced desire to exercise

• Higher inflammation

• Forcing thinness

B. Metabolic Overhaul

• Higher metabolic rate

• Healthier

• Lower risk of disease

• Fitter

• Lower inflammation

• Encouraging leanness

Encouraging Leanness

• Reversal to our natural state does not need to be forced, it just needs to be allowed to happen…

Remove toxins both internal and external

Food toxins/intolerances• Refined grains

• Dairy

• Eggs

• Fructose

• Trans-fats

• Sweeteners

• Chemical cosmetics

• Preservatives

• Alcohol

Replace nutrients

• Fibre

• Vitamins – D

– B12

• Minerals– Zinc

– Magnesium

• Fats– Omega 3

• Protein

Repair Lifestyle

• Train

– Apply

• Sleep

• Work/life balance

• Caffeine

• Meditate, Yoga etc.

Then all you need to consider with calories is this:

Are you hungry?

Yes? Eat

No? Don’t
