Experts have different opinions when it comes to the diets that people should adopt if they want to lose weight. Scientists at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) have compared a low-carb diet with a low-fat diet and found out that a low-fat diet is more efficient than a low-carb diet when it comes to losing weight. The results were published in the journal Cell Metabolism.
19 obese people were involved in the study. Their average age was 35. In the first stage of the study the participants were on a diet of 2.740 calories per day for five days. 50 percent of the calories came from carbs, 35 percent from fat and from protein there were 15 percent. In the second part of the study the participants cut 30 calories from their diet by reducing the carbs intake.
Afterwards they took a break that lasted a few weeks and resumed the baseline diet for five days. After that they reduced 30 calories from their diet for six days but this time they reduced the fat intake. During the days when the participants were on a diet they were in the laboratory so the researchers closely monitored what they consumed.
The findings of the study indicate that calories are not equal when it comes to losing weight. It seems that after a long period of time, irrespective of the carb-to-fat ratios your body will reduce body fat differences between diets containing the same amount of calories.
Metabolism researcher Kevin Hall from the National Institute of Diabetes and Digestive and Kidney Diseases said:
We are trying to do very careful studies in humans to better understand the underlying physiology that will one day be able to help generate better recommendations about day-to-day dieting. But there is currently a gap between our understanding of the physiology and our ability to make effective diet recommendations for lasting weight loss.”
However the researchers admit that the study has its limitations due to the fact that it involved a small number of participants and because it did not last a long time. For now researchers cannot say for sure what type of diet is better in a real-life situation. According to Hall the best option is to choose a diet which you are sure that you can stick to.
