People in the United Kingdom have lost twice as much weight of eating food, usually produced at home than eating ultraraprocele -based healthy foods, and have found the latest research.
“This new study shows that even when the ultraiprociated diet matches nutrition guidelines, people will still lose more weight by eating a minimally processed diet,” said co -author dr. Kevin Hall, a former senior researcher at the US National Institutes of Health, has conducted only a few world -controlled clinical studies on ultraoproce.
“This (study) is the largest and longest randomized clinical examination of ultraprocessed foods so far,” Hall added.
Previous studies of Hall have one month to distinguish between healthy volunteers from the world, measuring the influence of ultraperinth food on their weight, body fat and various health biomarkers. 2019 During the study, he found that people in the United States ate about 500 calories every day and gained weight when they followed an ultraraproced diet, nor eating a minimally recycled diet agreed with calories and nutrients.
During the new study, a minimally processed food weight loss was modest – only 2% of a person’s initial weight, said Samuel Dicken, author of Study First, researcher at the University of London College of College.

“Although the 2% decrease may not look very large, it is only more than eight weeks and without people trying to actively reduce their (food) consumption,” the Dicken said in a statement. “If we increased these results a year, we would believe that men’s weight would be reduced by 13% and 9% of women would be reduced.”
Usually men have more lean muscle mass than women, which, along with testosterone, often gives them a faster impetus for women when they need to lose weight, experts say.
Healthier ultraprocessed food
A study published on Nature Medicine on Monday for eight weeks to supply a free ultraprocin or minimally recycled dish and snacks for 55 overweight people in the UK. After a short break, the group moved to the opposite diet for another eight weeks.
The participants were told to eat as much as little or so many of the 4,000 daily calories as they liked and record their use in a blog. At the end of the study, 50 people spent eight weeks for both diets; Although the number of participants may seem small at first glance, it may seem at first glance that 16 weeks of food and implementing randomized clinical trials may be expensive.
For the first eight weeks, 28 people received minimally processed dishes and snacks such as oats overnight and homemade spaghetti Bologna.
According to Nova, minimally processed foods, such as fruits, vegetables, meat, milk and eggs, usually cooked from the natural state, according to Nova, the recognized food categorization system according to their level of recycling.
At the same time, for eight weeks, another 27 people received ultraprocessed foods daily, such as breakfast bars or heat and eating lasagna.
Based on the NOVA classification system, especially in ultraraprocede foods or UPFS, there are additives, never or rarely used in kitchens and often processed extensively industrial processing.
Because ultraprocins in foods are usually high in calories, added sugar, sodium and saturated fat and low fiber, they were associated with weight gain and obesity and chronic diseases, including cancer, cardiovascular disease, type 2 diabetes and depression. Such food can even shorten life.
But researchers in this study did something unusual, said Christopher Gardner, a Rehnborg Farquhar medical professor at Stanford University in California, who heads the Stanford Prevention Research Center Nutrition Research Group.
“They tried to hold a healthy ultrapercine diet by choosing ultraprocessed food with the recommended number of fruits, vegetables and fiber and a lower amount of salt, sugar and saturated fat,” said Gardner, who did not participate in the study.
Both ultraprocked and minimally processed food had to meet Eatwell Guide, the UK’s official government tips on how to eat a healthy, balanced diet, nutrition requirements. The US has similar diet guidelines used to set federal nutritional standards.
“This is a very strong study that corresponds to the dietary intervention of the distribution of nutrients and food groups, while changing only the contribution of particularly processed foods,” In the letter dr. David Katz, a preventive and lifestyle medical specialist. Katz, who has not participated in the study, is the founder of the TRUE Health initiative, the founder of the global coalition of experts to make evidence -based lifestyle medicine.
Linging of ultraprocessed food
The aim of the study was to lose weight, which is often improved in cardiovascular blood vessels such as lower blood pressure, blood cholesterol and blood sugar.
It happened, but quite strangely and surprising, said Marion Nestle, New York University Nutrition, Food Study and Public Health Emerita Palette Goddard Emerita, who was asked to write an editorial office that would be published with the study.
Instead of gaining weight, the ultraprocesshed diet people chose to eat 120 less calories a day, thus losing weight. People who hold in a minimally processed diet have ate 290 calories a day, losing even more weight and some body fat.
“One of the possible explanations is that (people who consider a minimally processed diet)” healthy “dishes did not like as much as their regular diet,” wrote a Nestle that did not participate in the study, wrote in the editorial office.
“They considered a less delicious diet,” Nestle said. “This diet emphasized the ‘real’ fresh food, while the highly processed diet contained commercially packed ‘healthy’ foods such as fruits, nuts and protein bars; sandwiches and meals; Drinking yogurts and plants of the plants. ”
According to the study, fewer than 1% of the UK people follow all government nutritional recommendations, often choosing ultraiprociated foods as a basis for normal daily consumption. In the US, almost 60% of adult calories consume from ultraprocessed foods.
“People in this study were overweight or obese and have already eaten a diet that is rich in ultrapercinth foods,” Gardner said. “So the ultraraproced diet in the study was healthier than their typical normal diet. Isn’t this a strange turn?”
People who consider the minimally processed diet had a lower level of triglycerides, the type of fat in the blood associated with the increased risk of heart disease and stroke, but other heart health markers did not differ significantly between two diets, the study writes.
There was one noticeable exception: low density lipoprotein or LDL, known as “bad” cholesterol as it can accumulate in the arteries and create clogging in the heart.
“It is strange that LDL cholesterol was more reduced due to a particularly treated diet,” said Dietian Dimitrios Koutoukidis, an associate professor at the Oxford University diet, obesity and behavioral sciences that did not participate in the study.
“This may mean that processing is not as important for heart health if foods already match the standard UK healthy eating tips,” the Koutoukidis said in a statement. “Additional research is needed to understand this better.”
According to Hall, the results are quite beautifully corresponding to the preliminary results of his current study, which is still in progress. In that study, Hall and his team have measured the impact of four ultraproceles on food configurations on the health of 36 volunteers. Every month he lived in the metabolic clinical study department of the Clinical Center of the National Health Center in Bethesda, Maryland.
“When you modify an ultraprocessed diet for lower energy (calorie) density and less delicious food, you can compensate for some of the effects of ultraprocessed foods, causing excess calorie intake and weight gain,” Hall said.
In other words, choose healthier food despite the level of processing.
“People do not eat the best ultraperrative food, they eat the worst, so take home here to follow national nutrient quality guidelines,” Gardner said.
“Read your nutrient label and choose foods that are low in salt, fat, sugar and calories and a lot of fiber, and avoid food that contains too many additives that are not transmitted. This is a healthier diet key.”
