Olisi siis fokusoiduttava lihottavimpien ruokien syönnin vähentämiseen. Ultraprosessoitujen. Tässä tutkimuksessa tosin osoitettiin vain vain korrelaatio
ultraprosessoitujen elintarvikkeiden ja lihavuuden välillä. Muissa tutkimuksissa on osoitettu, että ne saavat syömään enemmän.

Päätutkija Herman Pontzer:In A Nutshell
A global study of 4,213 adults finds that people in wealthier countries actually burn more daily calories than those in traditional lifestyles.
Obesity in developed nations is not driven by inactivity but by increased intake, especially of ultra-processed foods.
Physical activity levels did not significantly decline with economic development, challenging common obesity assumptions.
The percentage of ultra-processed food in the diet was strongly linked to higher body fat, suggesting food quality—not movement—is the key issue.
It remains to be determined what dietary factors are the most fattening. In an exploratory analysis, we found no effect of % meat in the diet, but % calories from ultra-processed food was strongly related to body fat%
Importantly, we also found that the extra calories available in developed populations aren't all bad. Rich populations are taller and have more (healthy) lean mass than less dev'd pops. So what do we need to do?
We need to focus on diet if we want to end the obesity crisis. And we need to focus on the obesogenic foods (UPF maybe?) while, hopefully, maintaining the availability of healthy calories.
These aren't new ideas, but hopefully this paper helps clarify & amplify those efforts
