The Claim

In obese adults undergoing energy restriction, baseline ultra-processed food intake was approximately 22% and remained above 20% after 12 months, indicating that the population studied had consistently low ultra-processed food consumption and may not represent individuals with high intake levels, thereby limiting the generalizability of the findings.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

In a study of obese adults on a calorie-restricted diet, ultra-processed food intake started at about 22% and stayed above 20% throughout the year, meaning the participants did not consume high amounts of ultra-processed foods and may not represent people who do.

See the scientific wording

In obese adults undergoing energy restriction, baseline ultra-processed food intake was low (approximately 22%) and remained above 20% in both groups after 12 months, suggesting that the population studied may not be representative of those with high ultra-processed food consumption, limiting the generalizability of findings.

Why this might work

People who start with a diet low in ultra-processed foods continue to consume them at low levels even when trying to eat less, because their eating habits do not change significantly during calorie restriction.

    The people in the study were already eating only a little junk food to begin with, and even after trying to eat less, many still ate more than 20% junk food — so the results might not apply to people who eat a lot of ultra-processed foods.
