Study: Both Cut Fat or Carbohydrate to Lose Weight

Study: Both Cut Fat or Carbohydrate to Lose Weight

In new research, volunteers who adhered to the low-carb diet and those who reduced their fat intake lost the same amount of weight

What’s Better to Lose Weight : Eat Less Carbohydrate or Fat? It’s the same thing. A study by the Stanford University School of Medicine in the United States, published in the respected scientific journal JAMA on Tuesday (20), points out.

We’ve all heard stories from a friend who went on a diet and worked very well. Then someone else tried the same diet and it did not work out so well, “says lead researcher Christopher Gardner in a press release. “This is because we are very different and we are beginning to understand the reasons for all this diversity. Maybe we should not ask ‘what’s the best diet ?’, But ‘what’s the best diet for each?’ “

To better understand this scenario, Christopher and his team recruited 609 volunteers (half men and half women), all aged between 18 and 50 years. Participants were randomly divided into two groups: one who followed a low carbohydrate diet and one that reduced the amount of fat ingested. Both classes were instructed to follow their respective eating patterns for one year.

At the outset of the research, the scientists also analyzed the genetic and metabolic predisposition of individuals to respond to diets. The volunteers underwent DNA testing and measurement of insulin levels.

Over 12 Months

In the first eight weeks of the research, participants limited daily carbohydrate or fat intake to just 20 grams – the equivalent of 1½ slice of whole grain bread or a generous handful of oilseeds.

From the second month, men and women gradually increased their intake of the two nutrients until they reached amounts that they could maintain for the rest of their lives. At the end of a year, low-carb supporters ate on average 132 grams of carbohydrate per day; while followers of a low-fat menu consumed 57 grams of the macronutrient daily. To get an idea, before the survey, these values ​​were 247 grams of carbo and 87 grams of fat per day.

And it was not just the size of the dish that changed with the study – the food choices of the participants improved a lot. “We told everyone that regardless of what diet they were following, they should go to free shows, not to stores that only sell processed products,” says Christopher.

Another orientation of scholars to volunteers is to eat in quantities that do not make them hungry. “Otherwise, it is difficult to follow a long-term diet,” he says.

Everyone in the Same

After one year, the two classes had the same mean weight loss: -5.8 kg. In addition, the authors found that the genetics of each and insulin levels are not determinant in the success of the diet – contrary to what previous research has shown.
