The plots of low & stable men's BMI's until 1945 were thought-provoking.
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 men's 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.
What happened in the US in 1945 to make men's BMI rise slowly? After World War 2, the economy was in a slump and something had to be done to get people to consume more, to stimulate economic growth. Corporations changed the way that they marketed to people. Instead of telling people facts about their products, they began to connect with people emotionally. It worked.
Edward Bernays pioneered the psychological tricks used by the Food Product Industry to get people to want things that they didn't need and consume more. For more information about Edward Bernays, watch The Century Of The Self Part 1 of 4 Happiness Machines.
Watch also Unreported World: Obesity in Paradise. At 6:50, a Samoan explains why they prefer to buy the more expensive imported "crap-in-a-bag/box/bottle" instead of their own inexpensive locally grown produce - they believe that imported foods are superior to locally grown foods. I wonder how that belief got into their heads? At 19:40, you can see an example of the inefficacy of healthy eating guidelines.

Once a child has adopted poor dietary habits, it's difficult to reverse them. As children are easier to manipulate than adults, there are regulations aimed at restricting marketing to children, regulations which the Food Product Industry finds ways to bypass.

Chronic consumption of "crap-in-a-bag/box/bottle" foods high in sugars and fats induces insulin resistance in the hypothalamus resulting in impaired satiety, increased hunger and an increase in food consumption. Ref: The role of fatty acids in insulin resistance.
One of Edward Bernays's psychological 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 more public confusion and more mistrust of researchers & science.
The Tobacco Industry used Bernays's psychological 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 wrongly focusing on foods/macronutrients/micronutrients/healthy eating advice etc, people like Taubes, Teicholz, Malhotra, Noakes etc are helping the Food Product Industry to continue manipulating the masses to over-consume over-refined Food Products.
What happened in the US in 1990 to make men's BMI rise rapidly? As total kcals/day didn't suddenly start to increase significantly in 1990 (see 2.), it wasn't due to food intake suddenly starting to increase significantly. See https://twitter.com/KlausKblog/status/867772729264447488 Either energy expenditure suddenly started to decrease significantly, or it was the Pharmaceutical Industry.
