“These dietary fads tend to come and go,” Dr. Ronald Krauss, of Children’s Hospital Oakland Research Institute, in Oakland, California, said.
“In the case of low carbohydrates, people shouldn’t be so quick to throw that away and move on to the next diet.”
“Limiting carbohydrates can be beneficial even if people aren’t successful at losing weight.”
Scientists believe carbohydrates can lead to unhealthy changes in blood fats by causing fat to collect in the liver – just as it does on one’s thighs.
These fats eventually find their way into the bloodstream.
Limiting these fat deposits by cutting carbs reduces fat levels in the blood.
To investigate whether moderate reduction in carbohydrate intake might affect cholesterol levels, Krauss and his team had a group of 178 overweight men eat a standard diet, including 54 per cent energy intake from carbohydrates for one week. The men were then randomly assigned to continue the same diet, or switch to a 39 per cent carbohydrate diet, or a 26 per cent carb diet for three weeks.
For an additional five weeks, the men had a similar diet, but their calorie intakes were reduced to produce weight loss.
In the final four weeks, their energy intake was adjusted for weight stabilisation.
Those with the lowest carb intake showed reductions in harmful triglycerides and “bad” LDL cholesterol levels.
These changes were seen whether or not the men were eating less saturated fat, and whether or not they lost weight.
The 54 per cent carbohydrate diet resembles the normal diet we consume with standard dietary recommendations.
Krauss said people can cut their carbohydrate intake by avoiding items such as sugary foods, white rice, pasta and white bread.
“This type of diet really needs to be done in consultation with a dietitian to get the balance that we used,” he said.
But such a diet, he noted, is simple and less restrictive.
