Brazil is home to some of the world’s highest rates of obesity, with an estimated 10 million people living with a body mass index (BMI) of over 30.
This means that a diet high in carbohydrate can make you feel full for longer.
There are also serious health problems associated with high-glycemic-index foods, like diabetes and heart disease.
But the world is now experiencing a new wave of obesity.
A study published in the European Journal of Clinical Nutrition (EJCN) in December found that people who were overweight or obese at the time of the study were more likely to have the condition again if they switched to a low-carb diet.
The study also found that the type of diet affected by this change was also linked to more weight gain.
“This is a significant finding,” said Dr Tariq Tafreshi, the lead author of the new study, in a statement.
“It indicates that carbohydrate consumption may play a role in weight gain.”
The study found that when participants were switched to lower-carbohydrate diets, the body gained about 10 per cent more weight over the first 12 months.
The researchers said the diet they used had no effect on overall body weight, but was linked to a higher risk of type 2 diabetes, hypertension and other cardiovascular problems.
A previous study also linked a high-protein diet to an increased risk of heart disease and diabetes, although the link was stronger for the more restrictive high-fat diet.
However, the new research suggests that this is not the case for everyone.
“If you eat a high fat diet you are not going to gain weight,” Dr Tafeshi said.
“But if you eat one that’s low in fat, like a Mediterranean or South American diet, then you will gain weight.”
Low-carb diets and high-calorie food Many people find it difficult to avoid the low-fat, high-sugar, high carb diet in their diet.
This is partly because it has been associated with a number of health problems, including cardiovascular disease, diabetes and cancer.
“We all know that saturated fat has a very bad impact on the body,” said Andrew Burt, a professor of dietetics at the University of Melbourne.
“So people have a very hard time maintaining a healthy diet and avoiding saturated fat.”
But the high-fructose corn syrup (HFCS) diet, which has become popular in the US and Europe, has been shown to be more beneficial than the low carb diet.
It is low in carbohydrates, low in sugar and has been linked to lower levels of insulin, an important factor in regulating blood sugar levels.
But it also contains large amounts of sugar, so many people find that they have to adjust their diet accordingly.
For some people, this can be difficult to do without feeling bloated.
“There’s a lot of misconceptions that a low carb or low fat diet is healthier and better than a high carb or high fat one,” Dr Burt said.
The latest study also shows that those who switched to low-caloric diets were more than three times more likely than the control group to gain more weight, and to gain a BMI that was at least 2.5 points higher.
Low-calorically processed foods Low-salt and processed foods, which include pizza, pasta and pizza sauce, are also high in carbohydrates.
“Low-saturated fats like olive oil are really great for heart health,” said Tafshik, adding that people should also aim to limit saturated fats and refined carbohydrates, which have been linked with heart disease, cancer and stroke.
“The good news is that most of the health benefits associated with low-sodium diets are also associated with reducing the risk of cardiovascular disease,” Dr Kavita Goyal, a clinical nutritionist and researcher at the Mayo Clinic, said in a release.
“However, because there is not enough data on these things, it’s really hard to say exactly what is the best approach to managing these risk factors.”
Dr Bostock, from the Australian National University, said that while the findings suggest that low-glycaemic-index (GI) foods, such as fruits and vegetables, may be better for people with obesity, there are still other factors to consider.
“I don’t think people are eating enough low-GI food, or that it’s good to consume lots of low-nutrient foods,” he said.
Dr Kavanagh added: “I think there are people who are overweight, people who have diabetes and people who suffer from chronic disease, and they need to be eating a low GI diet.”
Dr Kavinagh said that the main way people can make a difference is to change their diet to one that is less high in sugar.
“They can do this by reducing their intake of foods that are high in sugars, like sweets, sugary drinks and fast foods,” she said. A low-
