Diets containing high amounts of ultra-processed foods yield less efficient weight loss compared to diets with fewer such foods.

In a recent study, researchers have compared the effects of minimally processed and ultraprocessed diets on weight loss and health. The findings suggest significant differences between the two, with implications for those aiming to maintain a healthy weight and improve cardiometabolic health.

The study proposes a 2% reduction over eight weeks with a minimally processed diet. If extrapolated over a year, this could result in a 13% weight reduction in men and a 9% reduction in women. In contrast, the expected weight reduction with an ultraprocessed diet is 4% in men and 5% in women over the same period.

One of the key findings of the study is the improvement in body composition related to cardiometabolic health measures with the minimally processed diet. This includes reductions in fat mass, visceral fat, and triglyceride levels. The ultraprocessed diet, on the other hand, was found to lower LDL cholesterol levels.

Interestingly, the study showed significantly greater improvements in the number of cravings and the ability to resist them with the minimally processed diet compared to ultra-processed foods. This suggests that the minimally processed diet may help in controlling eating habits more effectively.

Despite these benefits, the taste and flavor of the ultraprocessed diet were rated higher than the minimally processed one. However, the minimally processed diet significantly improved the general control of the desire to eat compared to the ultraprocessed diet.

The terms "processed" or "ultra-processed" have taken on a negative connotation due to their health effects, primarily of the latter. The addition of low-quality, cheap, and sometimes harmful ingredients has made ultra-processed food a target, especially when trying to follow a healthy diet that also helps with weight loss.

It's worth noting that more than 50% of the foods consumed in the UK, US, and Europe are ultra-processed. The largest producers of these foods are primarily major multinational food corporations such as Nestlé, PepsiCo, Unilever, Coca-Cola, Mondelez, and Danone. These companies dominate the market with a wide range of packaged snacks, sugary beverages, ready meals, and processed food products.

In conclusion, while the taste of ultra-processed foods may be appealing, the study underscores the importance of considering the long-term health effects when making dietary choices. The benefits of a minimally processed diet, particularly in terms of weight loss and cardiometabolic health, should not be overlooked.
