Many people believe that as long as they’re eating fewer calories, they’re making healthier choices. But new research suggests that the type of food you eat may be just as important as the number of calories it contains.
A recent study found that men who ate an ultra-processed diet experienced changes in body composition and hormone levels even when their calorie intake was similar to those eating minimally processed foods.
Calories Aren’t the Whole Story
Researchers found that men eating ultra-processed foods gained about 2 pounds of body fat, despite consuming the same number of calories as those eating less processed meals. They also showed less favorable markers related to heart and metabolic health.
These findings suggest that your body may respond differently to processed and minimally processed foods, even when calorie intake is nearly identical.
The Study Also Looked at Hormones
Beyond weight gain, researchers observed lower testosterone levels and reduced levels of follicle-stimulating hormone (FSH), both of which play important roles in male reproductive health.
Participants eating more ultra-processed foods also had higher levels of certain environmental pollutants that have been linked to reduced sperm quality. While these findings are concerning, experts emphasize that they do not prove infertility, and more research is needed to better understand the long-term effects.
What Experts Say
Researchers noted that eating ultra-processed foods may be harmful to both cardiometabolic and reproductive health, even when people aren’t consuming excess calories. Their findings suggest that the quality of the foods we eat may influence health in ways that go beyond calorie intake alone.
Health experts say the study adds to growing evidence that diet quality, not just calorie intake, plays an important role in men’s metabolic and reproductive health. At the same time, they caution that the findings came from a study involving healthy younger men, so they shouldn’t yet be applied to older adults or people with existing health conditions.
Experts also emphasize that while the short-term drops in testosterone and sperm quality observed in the study do not prove infertility, they may represent early changes that warrant further research.
What to Remember
Cutting calories can be helpful for weight management, but what you eat matters just as much as how much you eat. Replacing highly processed foods with more whole foods may support a healthier metabolism and overall well-being.
While more research is still needed, this study serves as another reminder that building meals around minimally processed, nutrient-rich foods can offer benefits that go beyond the number on the nutrition label.
