The breakfast is often said to be the most important dish of the day, but according to a new review Wednesday at the BMJ, it will not help you lose weight. The study found no good evidence that regular breakfast helps reduce calories or avoid weight gain. Even more surprising, he even found some evidence that skipping breakfast would be better for our waist ̵

There are good reasons to consume early in the day, especially if you are young. Studies show that regular healthy eating (thinks fruits, vegetables, and whole grains) helps children and teens develop normally and stay sharp at school. Many public health organizations and doctors have similarly recommended adding a healthy breakfast to your daily routine as a way to prevent obesity or to promote weight loss.
The theory behind this advice is simple: early nutrition will speed up your metabolism and protect you from feeling more hungry and overeating at a later meal. There is evidence of this theory from some research. These studies are usually monitored, but this means that they are only looking for indirect links between two things (in this example, eating or skipping breakfast and losing weight or less obesity) in a group of people of a decent size. But in the last few years, some randomized and controlled studies, often considered a gold standard of evidence, failed to find the same relationship.
"The problem is that those who eat breakfast are usually different from those who do not. T. Therefore, the observation problem is that it is not a good breakfast, but rather a healthy lifestyle and the choice of food that results in gains in weight, "said senior author Flavia Cicuttini, an epidemiologist at Monash University in Australia. , he told Gizmodo by e-mail.
Cicuttini and her team decided to select and analyze as many clinical trials as they could find to solve the issue, something scientists call meta-analysis. They examined 13 trials conducted in the United States, Great Britain and Japan between 1992 and 2016, which together studied more than 500 adults with a different body weight and body mass index. Some of the tests tested if the addition or skipping of breakfast can affect the weight; others looked at whether breakfast would affect a person's total calories in a day.
"We found that those who ate breakfast generally eaten about 260 extra calories a day more and on average grew by 0.44 kilograms [roughly a pound]," says Cicuttini. "It is important that there is no evidence of improved metabolism in those who eat breakfast or that they are less likely to overeat later in the day."
This pattern is retained regardless of where the studies were conducted or how much the volunteers weighed. 19659004] The authors have added their findings, which should not be considered as final. On the one hand, the overall quality of the evidence reviewed is considered to be low. Few studies blinded the volunteers, which meant they knew whether they were eating breakfast or not. Of course, this may be difficult to hide from someone, but studies also rarely blind the researchers who had to measure and calculate the results they had received from the volunteers – another non-science. All studies, according to the team, also had a high or unclear risk of bias.
The authors say that more research will be needed, preferably by large, high-quality studies to be completely secure. But at the same time, said Chikutini, there is a clear conclusion from the average person of their research.
"The main message is that if one likes to eat breakfast, that's good," she said. "However, there is no evidence that we need to encourage people to change their diet to include breakfast to prevent weight gain or obesity … This can do the opposite!"
