The Claim
Higher intake of ultra-processed foods is associated with adverse maternal weight outcomes during pregnancy, even after adjustment for total energy intake.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Women who consume more ultra-processed foods during pregnancy tend to gain more weight, even when their total calorie intake is accounted for.
See the scientific wording
The association between ultra-processed food intake and maternal weight outcomes persists after adjusting for total energy intake, suggesting that factors beyond calorie quantity—such as food composition, additives, or eating behavior—may contribute to weight gain during pregnancy.
Eating ultra-processed foods changes the bacteria in the gut, which triggers hormones that make the body store more fat and feel less full, leading to weight gain even when calorie intake stays the same.
What the research says
1 studyEven when pregnant women eat the same number of calories, those who eat more ultra-processed foods like chips and soda still gain more weight and keep it on after birth—showing that what you eat matters as much as how much you eat.
