50 years ago, people were slimmer and stronger without counting calories or going to the gym.
Then, something changed at the end of the 20th century, and muscle mass began to decrease while obesity increased.
No, it wasn't because of doing less exercise…
Here's what really happened:🧵
In the 1960s and 1970s, the average American got around 14–15% of their calories from protein.
Today, that figure has dropped to about 12%.
It may seem like a small difference, but it triggered a change in your body so powerful that most people don't even realize it's controlling them at this very moment.
Here's why…
There is a concept called the Protein Leverage Hypothesis.
It posits that your body has a strong biological drive to obtain sufficient protein.
If your diet is low in protein, you will overeat carbohydrates and fats until you reach your protein target.
