Hypothesis
The UPF meal would show a faster rate of intake, with a decreased ability to suppress feelings of post-prandial hunger.
Conclusion
A meal composed of ultra-processed foods leads to a higher rate of intake and is less likely to reduce the capacity to eat compared to a similar meal without ultra-processed foods.
Supporting Evidence
- Participants who consumed a UPF meal had a significantly faster intake rate compared to the control group.
- The UPF meal led to fewer chews and bites during consumption.
- Despite the faster intake, there were no significant differences in metabolic outcomes between the two meal types.
- Leptin levels decreased less after the UPF meal compared to the control meal when adjusted for sex.
Takeaway
Eating ultra-processed foods makes you eat faster and feel less full, which might not be good for your health.
Methodology
This was a parallel, randomized trial where adults with obesity consumed one of two test meals matched for energy density and macronutrients.
Potential Biases
The study was open-label, which may introduce bias as participants could identify the meal types.
Limitations
The study was small and underpowered, and the results are based on an acute effect observed after a single meal.
Participant Demographics
42 individuals with obesity, predominantly female (71.4%).
