The Elephant in the Room.

On Twitter about two weeks ago, Max Roser tweeted the following graphic:
From Health and the Economy in the United States from 1750 to the Present

The plots of low & stable BMI's until ~1945 made me think.

1. Over-refined sugars & starches entered the US food supply in ~1880. Ref: How the Mid-Victorians Worked, Ate and Died. ∴ Over-refined sugars & starches don't cause obesity.

2. Americans ate more carbohydrate per day from 1909 to 1929 than they do now. Ref: 3rd Fig. from More Thoughts on Macronutrient Trends. ∴ Carbohydrates don't cause obesity.

3. The "low-fat" dietary guidelines were issued in 1980. The two dates at which BMI began to increase significantly are ~1945 (slow rate of increase) and ~1990 (rapid rate of increase). ∴ The 1980 "low-fat" dietary guidelines didn't cause obesity.

So, what happened in the US in ~1945? From my comment HERE:
"After World War 2, the economy was in a slump and something had to be done to get people to buy more stuff, to stimulate economic growth. Corporations changed the way that they marketed to people. Instead of appealing to people’s logic, they began to appeal to people’s emotions. It worked.

Edward Bernays pioneered all of the dirty tricks used by the Food Product Industry to get people to over-consume. Ref: http://www.dailymotion.com/video/x2d29tf_the-century-of-the-self-part-1-of-4-happiness-machines_school

One of Bernays' dirty tricks is confusing the public by promulgating conflicting information. The Tobacco Industry paid health professionals to advertise cigarettes. On the one hand, you had researchers telling people that smoking was bad for them and on the other hand you had a doctor on TV saying that he preferred to smoke Camel cigarettes. This confused the public and made them mistrust researchers & science. Another dirty trick was setting-up organisations with scientific-sounding names to promulgate conflicting reports which the press published as “science”, saying that “X” was good for you, then some time later “X” was bad for you, then some time later “X” was good for you again and so on. The public mistrusted researchers & science even more.

The recent NOF report from Malhotra et al telling people to eat more fat is conflicting information, resulting in even more public confusion and even more mistrust of researchers & science. This is exactly what the Food Product Industry wants."

The Tobacco Industry used Bernays' dirty tricks to encourage women to smoke in public by making smoking a women's rights issue. Cigarettes were marketed to women as "Torches of Freedom". From the 1920's, women became as free as men to greatly increase their risk of getting Emphysema a.k.a. Chronic Obstructive Pulmonary Disease, Lung Cancer & Coronary Heart Disease, while the Tobacco Industry's profits increased.

By focusing on foods/macronutrients/micronutrients etc, people like Taubes, Teicholz, Malhotra et al are helping the Food Product Industry to manipulate the masses to over-consume their products.


So, what happened in the US in ~1990? Which dirty trick used by the Food Product Industry caused the rapid rate of increase in BMI from ~1990?

The cause of America's rising obesity rate is irrelevant. The cure for it is what's important.

NuSi go home. You're not needed!
From http://dietdatabase.com/causes-of-obesity/

On a blog comments section somewhere, a argument discussion took place about what caused America's rising obesity rate. Certain people have a hypothesis that there's one cause. Here's a rough list, in no particular order:-
Carbohydrates (Taubes)
Refined Sugar (Yudkin. Lustig)
Refined Fructose (Lustig)
Wheat/Gluten Grains (Davis)
Fat (Ornish, Esseltyn etc)
Saturated Fat (Ornish, Esseltyn etc)
Animal Protein (Vegans)
Mineral Imbalances (Karlsson, "Duck Dodgers")
The Government (Nikoley)
Dietary Guidelines (Teicholz et al)

It's not Refined Sugar. Sorry, John Yudkin & Robert Lustig. See below...
Refined Sugar intake (kcal/capita/day) is higher in France than in the USA, but in France there's a lower obesity rate. ∴ Hypothesis disproved*.

*As the Refined Sugar intake data may be unreliable (it's also associational data), the hypothesis is not necessarily disproved. If only there's an interventional study (which proves causation) which results in lower weight on a higher sugar/fructose intake. There is! See The effect of two energy-restricted diets, a low-fructose diet versus a moderate natural fructose diet, on weight loss and metabolic syndrome parameters: a randomized controlled trial. ∴ Hypothesis disproved.

I asked Duck Dodgers what he wanted to happen. He said:-
"My feeling is that if people recognize that enriched foods are the antithesis of whole foods, then the demand for enriched/refined foods may diminish, forcing the industry to change."

I want people to eschew refined foods for whole foods, too. So all the arguing about what caused America's rising obesity rate was a complete waste of time. This gave me an idea. I decided to run my idea past someone who deals with obese people with T2DM and who just happened to be in the U.K, attending the Health Unplugged Conference, I PM'ed Dr. Jeffrey Gerber on Facebook, inviting him to meet me at Cafe Class in Woking (a location roughly half-way between my home and London).

So this happened...
Ivor Cummins came, too!

Suffice it to say, the afternoon was a blast!

Why using macronutrient percentages is so wrong.

From http://sciencelearn.org.nz/Contexts/Food-Function-and-Structure/Sci-Media/Images/Macronutrient-percentages

1. Deception

Consider Lies, damned lies and statistics, part n+1. Riera-Crichton et al.  

Relative fat intake in %E decreased and obesity increased.

The conclusion:- "Carbohydrates are fattening and fat is slimming." Yeah, right!

Absolute fat intake in grams/kcals increased after healthy eating guidelines (which weren't low-fat guidelines) came out in 1980, according to More Thoughts on Macronutrient Trends.

Gary Taubes & Nina Teicholz use this deliberate misrepresentation of data to create the false narrative that low-fat healthy eating guidelines caused the obesity epidemic in the US. It's a pack of lies.

2. The terms "Low Fat" and "High Fat" are meaningless

Take 55g of fat (500kcals), 125g of protein (500kcals) and 375g of carbohydrate (1,500kcals). It adds up to 2,500kcals, with a percentage C/F/P split of 60/20/20. It's a High Carb, Low Fat diet.

Now remove 125g of carbohydrate to leave 250g of carbohydrate (1000kcals). It now adds up to 2,000kcals, with a percentage C/F/P split of 50/25/25. It's still a High Carb, Low Fat diet.

Now remove another 125g of carbohydrate to leave 125g of carbohydrate (500kcals). It now adds up to 1,500kcals, with a percentage C/F/P split of 33/33/33. It's now a Medium Carb, Medium Fat Zone diet.

Now remove another 62.5g of carbohydrate to leave 62.5g of carbohydrate (250kcals). It now adds up to 1,250kcals, with a percentage C/F/P split of 20/40/40. It's now a Low Carb, Highish Fat diet.

Now remove another 62.5g of carbohydrate to leave 0g of carbohydrate (0kcals). It now adds up to 1,000kcals, with a percentage C/F/P split of 0/50/50. It's now a Very Low Carb, High Fat diet.

So, 55g/day of fat can be Low Fat, Medium Fat, Highish Fat or High Fat. Which leads to...

3. Confusion

When someone sees the term LCHF (Low Carb, High Fat), they think it means "Eat less carbohydrate and eat more fat". As changes in bodily stores are determined by Energy Balance, eating more fat leads to a slower rate of weight-loss (or even weight-gain), not a faster rate of weight-loss.

By all means cut the consumption of "bad" carbs, like burgers in buns, chips/fries, crisps/chips, pizza, cake, biscuits/cookies, chocolate and sugar sweetened beverages.

However, if you believe that "good" carbs like vegetable produce, legumes, whole grains and whole fruits make you fat and sick, you need to have your head examined, unless you're in the tiny percentage of the population who have genetic carbohydrate intolerance.
