The clinical trial, made up of 55 adults (mainly women) from the United Kingdom who was overweight or obesity, followed the participants in these diets for eight weeks each.
At the end of the test, participants eat mini-transformed processed foods such as overnight oats and homemade pasta or chicken dishes have lost about 2% of their basic weight. They have also self-deprecated more significant improvements in their ability to control the desires compared to people according to the ultra-work diet.
However, people with an ultra -suitable diet also lost weight – about 1% of their base – eat items like frozen meals and breakfast bars.
“We did not expect to see the weight loss on the ultra-attractive diet, but this is probably because the participants had an unhealthy diet at the start who did not follow the food advice, and improved on the ultra-suitable diet,” said Samuel Dicken in England, author of health and at the center of obesity of the University of London.
Is the difference in weight loss significant?
Dr. Dicken and the other authors say that although a reduction of 2% weight on the mini-transformed diet may not seem much, it is remarkable for an eight-week period involving study subjects which do not actively try to eat less, and that in a year, this could result in a reduction in weight of 13% in men and 9% in women.
For people under an ultra -suitable diet, weight loss over one year could be much less – 5% in men, 4% in women.
“The results first highlight the importance of existing food advice,” explains Dicken. “Then, the choice of foods processed at least on ultra -adjustment foods can help lose weight more easily and maintain a healthier long -term weight – with advantages for body composition linked to cardiometabolic health.”
How the study worked
After being divided into two groups, a set of participants began eight weeks to eat mini-transformed processed foods before returning to their normal diet for four weeks as reset-then going to the ultra-tail diet for an additional eight weeks. The other group followed this food model in the opposite order.
With a large part of the existing evidence on processed foods from observation studies, this first interventional study of its kind aimed to study the causal links between food and weight results.
Can ultra-transformed foods be part of your diet in moderation?
The results of the study add a slight turn to previous research.
“In this new study, because the participants of the two groups have in fact lost weight, this calls into question the argument that ultra-transformed foods always promote weight gain when the balance of nutrients is maintained,” explains Stephen Finney, MD, primary care doctor and obesity medicine at Southcoast Health in North Dartmouth.
“The main difference was that the mini-transformed diet favored lower desires and food consumption despite equal macronutrients,” he adds.
But for experts like Courtney Pelitera, RDN, a dietitian-nutritionist recorded with better nutritional coaching in New York, the conclusion that weight loss can still occur while eating ultra-tranity food is encouraging when it comes to reducing judgment around food choices.
“This should give confidence that the consumption of processed foods in time in the context of a global healthy diet should not affect weight loss strategies,” said Pelitera. “A main priority is to eat on a coherent basis and feed your body as much as it should work optimally, then focus on adaptation to most of the whole food – but that should not be a mentality all or nothing. If one or two processed foods are in the diet every day, this study contributes to proving that a healthy weight loss can still be obtained.”
The study has certain limits
Study authors declare that the results may not be generalizable to all populations, as people with food restrictions, certain chronic diseases and other factors have been excluded from the trial. The researchers were also unable to measure the participants’ food intake directly or to confirm their membership in regimes outside of what was self -disclared.
Some other study limitations include the small size of the sample, the duration of the short trial and the food delivery model, which “does not reflect real access to food”, notes Dr Finney, stressing that food environments (which is available and marketed in a particular community) helps to shape health.
“In the meantime, I recommend that individuals aim to prepare simple meals when possible, to enjoy foods wrapped from time to time and to approach nutrition with flexibility and awareness,” he said. “The objective is long -term balance, not guilt.”
