Plant Extracts May Help Keep Hunger at Bay
Kidney bean and artichoke extract combination might help people feel full, eat less, lose weight, and maintain healthy blood sugar levels
Anyone who's tried to lose weight knows that it's easier if you're not hungry, and scientists tell us that blood sugar stability is one of the keys to keeping hunger at bay. A study published in Phytotherapy Research found that taking a before-meal supplement made from extracts of kidney bean and artichoke reduced appetite and improved blood sugar control in overweight people.
Bean and artichoke extracts reduce hunger
In the study, 40 overweight or obese men and women were divided into two groups: one group received a combination supplement providing 100 mg of an extract from kidney bean (Phaseolus vulgaris) and 200 mg of an extract from artichoke (Cynara scolymus), while the other group received placebo. The supplement or placebo was taken three times per day before meals for eight weeks. All of the participants received dietary counseling and were encouraged to eat a healthy low-calorie diet.
Researchers noted the following results:
Less appetite means less eating
In addition to these differences, the study's authors found that, according to scores from eating questionnaires filled out by all participants throughout the study, the plant extract group was more able to stay on the low-calorie diet than the placebo group. "As a matter of fact, the supplemented group showed a significant increase in the 'dietary restriction' score," they said. "Refraining from eating too much means a better control over food intake and consequently may be associated with success in weight loss and maintenance."
Eat to satisfy your appetite
The results of this study suggest that a kidney bean and artichoke extract combination might help people feel full, eat less, lose weight, and maintain healthy blood sugar levels. The plant chemicals in kidney beans and artichokes that are thought to be responsible for these effects are common to many other plant foods. Here are some things to keep in mind if you are trying to eat less and lose weight:
