A diet that’s high in fat, low in protein and low in carbohydrates is likely to be the best, according to a new report.
A diet high in protein, high in carbs and low on fat may be the worst.
And, as in any other risk management approach, the better the diet, the more likely it is to be effective, says Mark Sisson, a clinical professor of nutrition at New York University’s Langone Medical Center and one of the authors of the new research.
The researchers tracked more than 7,000 people for three years.
In one study, they asked the participants to lose about 1,000 calories a day.
The average weight loss was about 3.5kg (6lbs).
They also asked participants to follow a simple diet plan, which involved eating less than 2,500 calories a week and avoiding refined carbohydrates, sugar and refined protein.
For their final report, the researchers looked at the people’s health, health outcomes and other outcomes.
They also measured changes in their metabolic rates, waist circumference and blood pressure, as well as changes in blood pressure and waist-to-hip ratio.
The results were mixed, but not surprising, says Sisson.
“What we found was that the diet had some modest effects,” he says.
“There was a slight increase in waist circumference, but that wasn’t enough to significantly change the results.”
But there was also some positive news, says Dr. Daniel Sussman, a dietitian and co-author of the study.
“The more people followed the diet the worse they got,” he explains.
“When people were in the diet group they had a significantly lower risk of heart disease.”
Dr. Sussmann says it’s likely that the dietary changes that were made to help people lose weight would be helpful for those with metabolic syndrome.
However, the report also found that a diet high on carbs may not be the most effective.
Instead, it may be better to look for a diet that includes more protein, and fewer fat, he says, which could lead to a lower risk.
What does the research say?
There’s no hard evidence that eating a diet with a lot of carbs and fats has any health benefits, Sisson says.
In fact, he cautions that the evidence that there’s some benefit from high-fat diets is still “somewhat weak.”
“There is evidence that the high-carb diet can cause heart disease,” he adds.
“However, that evidence is still weak.”
“It is also not clear if the high fat diet is better for health, so it is worth exploring the evidence in this area.”
“We are still in the early stages of trying to find out the best diet for people with metabolic diseases,” Sussmans says.
He says he would recommend that people start eating a healthy diet, rather than cutting back on carbohydrates, protein and fat, and that people who have metabolic disorders look for alternative ways to eat to reduce the risk of disease.
“We don’t know the mechanisms that are going on that may be affecting metabolic syndrome,” he concludes.
“This is an area of active research, and we have to continue to find that out.”
