Study Says Fruits and Vegetables Don’t Lead to Greater Weight Loss
A new study from the University of Alabama at Birmingham says that increasing fruit and vegetable daily intake doesn’t lead to weight loss despite the old traditional belief. While adding them doesn’t promote weight change, it does help with fiber and vitamin intake each day.
The study’s investigators performed a thorough, systematic review as well as a meta-analysis of data from over 1,200 subjects in 7 different randomized and controlled trials. All of the trials focused on exploring the weight loss effects of increasing fruit and vegetable consumption in the issue’s daily diet.
The study’s leader, Kathryn Kaiser, Ph.D. and instructor at the UAB School of Public Health says that she doesn’t believe that eating more of them alone is an effective approach to losing weight because just adding them on whatever else a person is eating most likely won’t promote weight loss and might end up to increased caloric intake.
The recommended daily serving for adults is 1.5-2 cups of fruits and 2-3 cups of vegetables each day, according to the United States Department of Agriculture. Dieters are often told to fill up on fruits and vegetables since they are low-calorie food, which take up space in the digestive tract.
The study found that energy reduction is the best way to help a subject lose weight. To reduce weight, you must reduce caloric intake each day. Many dieters believe that eating higher fiber foods such as fruits and vegetables will help to displace less healthy food they’re eating. However in this study researchers found that they there is no effect on increasing fruits and vegetables in a diet for those seeking to lose weight. While they don’t do much for weight loss, they are still safe bets for dieters. However, they should never be consumed in extreme quantities.
Another study compared a Mediterranean diet to a reduced-fat diet; they found that while the former doesn’t promote weight loss it does reduce the risk of Type II Diabetes significantly more so than a reduced-fat diet.
Another study from the New England Journal of Medicine in 2013 evaluated patients who were at risk for cardiac disease and found that those who followed a Mediterranean diet were 30% less likely to have a stroke or heart attack than those on a low-fat diet.
While the focus on fruits and vegetables may be unnecessary, other studies mention foods such as eggs that do promote to weight loss. Their study says that eating two eggs for breakfast helps to lead to weight loss.
The study’s researchers believe that public health communications should be amended after this revealing result. The study’s researchers said that we want to send encouraging messages and telling people that eating more fruit and vegetables is important and better than telling them to eat less food to lose weight. They believe it’s important that people are told the truth about fruit and vegetables and not losing weight.
