1 . Both low-fat and low-carbon diets work equally well to help people lose weight over two years, a new research has shown. In addition, the low-carbon diets may also improve levels of HDL cholesterol(胆固醇), although it's not clear how much difference this would make to your overall health.
The search for a diet that helps people lose weight goes back decades. In recent years, there's been much discussion about the strong points of low-fat diets, compared with low-carbon diets. And some claim that the low-carbon diets work well for short-term weight loss, but there isn’t enough evidence to show how well the two types of diets work and what the effects are on people's health in the long term.
In addition, it's been recognized that weight-loss programs are better if they include some support to help people make changes to their eating and exercise habits. This is often called behavioral therapy, because it works through changing people's behavior.
The new study has researched people who followed a weight-loss program over two years, all of whom had behavioral therapy. According to the actual situation of different people, half the people followed a low-carbon diet, and half followed a low-fat diet. And the result shows: people on both diets did equally well in losing weight. After two years, they had lost on average 7 kilograms. This amount of weight loss is enough to have positive effects on the health of fat people. What’s more, the group who had the low-carbon diets had much better levels of HDL cholesterol than people on the low-fat diets.
If you need to lose weight, this study shows that the behavioral therapy is able to work effectively. You may find it easier to lose weight as part of a supervised weight-loss program that can help you break bad habits and make healthy changes to your diets and lifestyle.
