We DID NOT eat less prior to obesity.
We didn't even eat "healthy" by modern standards.
In fact, we ate lots of calories, fat, sugar and carbs.
This is what we used to REALLY eat, back when everyone was skinny (based on historical evidence):
(🧵1/11)

United states calorie supply:
1909 = ~3500 calories.
1989 = ~3500 calories.
Yet, obesity increased by about 10 FOLD.
What exactly were we eating? Well...
1909 = ~3500 calories.
1989 = ~3500 calories.
Yet, obesity increased by about 10 FOLD.
What exactly were we eating? Well...

We ate TONS of calories prior to the obesity epidemic.
Let's take a look at the 1939 USDA book of agriculture.
The more money people spent, the more calories were consumed.
On the low end: around 2,000.
On the high end: over 4,000, even close to 5,000 a day.
This is for a 154 pound man who was "moderately active."
This would be more active than a man today for sure, but the richest people would also be the least active of the day, yet no detectable obesity crisis.

We used to eat a high carb, high sugar, high fat, high calorie diet.
If we look at specific foods we get an idea of their diet.
Carbs: ≈ 430 g → ~1,700 kcal (~53% of energy)
ADDED SUGAR: ≈ 137 g
Protein: ≈ 110 g → ~430 kcal (~13% of energy)
Fat: ≈ 120 g → ~1,090 kcal (~34% of energy)
Total ≈ 3,200 cal/day for an average PERSON. Not even for an average adult man, average PERSON.
Plenty of potatoes, bread.
About half a pound of fruits + half a pound of vegetables a day.
It is true that some of this would go to waste, but it's unlikely that more than 10% would especially during this era of relative food insecurity.

Other key diet notes from late 40s/50s:
◈ 175g of carbs from grains (rice, flour, etc)
◈ 4 cups (!) of milk (& cream) daily
◈ No chicken recorded, main meat was PORK - about 6 oz of meat total a day

◈ 4 cups (!) of milk (& cream) daily

1955 - Food records were this time determined by interviewing house members.
The numbers line up well with the country wide consumption numbers.
➠ >2 cups of milk a day
➠ >1 cup of ICE CREAM per week
➠ 12 oz of proteins - over 8 oz of meat / fish
➠ ~1/2 pound of vegetables
➠ Orange juice + 6 oz of other fruit
➠ 92 grams of added sugar!

I was shocked to find out that they were actually on a higher fat diet.
➠ 44% of calories from fat
➠ 43% from carbs
A whopping 155g of fat a day!
65 grams of saturated fat!
4.5% of calories came from linoleic acid, the main fat in seed oils. This is about 1/3 of what we consume today.
Based on these numbers - we see an average intake of 3170 calories per day.

About HALF of the carbs consumed in 1955 were SUGARS, about 21% of the total diet.
The other half were starches.
This aligns with what I have been writing about recently, that sugar synergizes with starch metabolically as a part of the diet.

So how were people back then able to eat so much food, sugar, fat, etc and remain lean and healthy?
Sure, moving more is definitely a part of it, but even relatively generous estimates put that as accounting for 100 calories throughout the workday.
My take is that it's a TON of factors that all come together - death by 1000 cuts, if you will:
◇ More seed oils
◇ Less time outside (sunlight highly protective)
◇ Disrupted circadian rhythms
◇ Less nutritious food (less vitamins + minerals + phenolics and other protective compounds)
◇ Worse gut health (rise of antibiotics, C sections, food additives, overly sterilized environments)
and the list goes on and on. I'm writing about it constantly here.
Almost no one can eat like this today, because almost nobody has the metabolism of a person from the 1930s-50s.
Our goal should be to fix that.
