• Obesity has been a growing problem since the late 19th century, not just since 1980.
• The population aging has a mechanical impact on average obesity that is unrelated to changes in diet and nutrition.
• The average Americans’ weight change since the 1980s is startling, but the data suggests a much more boring story about a long-term increase in average weight punctuated by the Great Depression and World War II.
• Food insecurity was incredibly common for most of human history, but now spending on groceries has plummeted as a share of household spending.
• Food is also better across many dimensions of betterness, from ultra-processed junk food to home cooking.
