Using the white kidney bean for weight loss may be effective if combined with eating well and exercising.
White kidney beans are legumes also referred to as Phaseolus vulgaris, and more commonly, cannellini beans.
They are rich in an active constituent called phaseolamin which has been clinically shown to promote weight loss, and to generate other healthy effects, especially in obese individuals.
It has been implicated for improving blood-lipid profiling and possibly reducing the risk factors for coronary artery disease and heart disease.
Phaseolamin acts to partially block the digestion of starchy foods with high glycemic indices like lasagna, macaroni salad and bread. By limiting the amount of carbohydrates that are assimilated into the bloodstream, the total amount of metabolized glucose is reduced.
In other words, this supplement may help to block some of the calories you eat from entering your body, helping to promote a calorie deficit. If you can achieve a large enough calorie deficit when taking white kidney bean weight loss supplements, the result will be fat loss.

White Kidney Bean is purported to promote weight loss by blocking the activity of an enzyme that is necessary for the digestion of carbohydrates.
When carbohydrates enter the mouth, the salivary glands release a digestive enzyme called alpha-amylase.
It acts to begin breaking down complex carbohydrate molecules into more manageable particles for digestion.
This action continues to degrade the carbohydrates until the food reaches the stomach. The high acidity of the stomach acts to stop the alpha-amylase digestive action.
As the carbohydrate foods enter the small intestines, the pancreas releases more alpha-amylase to reinitiate the process. All digested carbohydrates, and other food sources, are then progressed to the large intestine and expelled via defecation.
When using white kidney beans for weight loss purposes, the phaseolamin contained in this supplement partially blocks the effects of alpha-amylase. In the mouth and small intestines, phaseolamin acts to inhibit the digestion of the starches.
Subsequently, the carbohydrates are passed on through the small and large intestines without having been digested and absorbed completely.
Reported Results of White Kidney Bean
When alpha-amylase is blocked by White Kidney Bean diet pills, the carbohydrates that are inhibited from digestion are either expelled in undigested form, or they are digested via fermentation in the colon.
During this fermentation process, byproducts are given off including butyric acid, acetic acid and propionic acid. These substances are believed to act against colon cancer development much like the actions of dietary fiber.
Other constituents of the starchy foods, like vitamins and minerals, are still digested and assimilated into the body. It is only the starch molecules that are left undigested via the action of phaseolamin.
As the carbohydrates that have not been digested, or at least have not been fully digested, leave the body, this means that glucose cannot be made from them and insulin levels are not raised as much. Since insulin plays a role in the storage of fat, this may be able to reduce the risk of weight gain.
A secondary effect of the carbohydrates passing through the system without any caloric footprint is that the body may then need to tap into fat reserves to gain additional energy. This also acts to encourage weight loss and subsequent weight maintenance.
Controlling blood glucose levels also has other benefits for health. Cardiovascular health benefits of white kidney beans for weight loss may include:
- Reduction is body weight, waist circumference and fat mass;
- Decreased projected fat mass;
- Decreased risk for developing obesity and numerous related conditions;
- Improving the glycemic indices of starchy foods;
- Reducing the risk of hypercholesterolemia, hypertriglyceridemia and atherosclerosis.
These positive benefits of phaseolamin supplementation can begin to onset quickly. In some studies, significant weight loss was observed within 30 days of beginning supplementation.
Is White Kidney Beans Safe?
Using white kidney beans for weight loss seems to be very safe.
The FDA has classified Phaseolus vulgaris as a GRAS food and no serious side effects have been reported or observed in clinical trials.
In some cases, gastrointestinal disturbances occur including gas, bloating and stomach upset. However, these effects are always fast to pass and mild in severity.
White kidney bean extracts are known to affect blood glucose levels. They act to lower blood sugar and to inhibit the sharp glucose spikes that many experience after eating carbohydrate-heavy meals.
For this reason, those who are taking insulin or any other medications for diabetes type II mellitus or reactive hypoglycemia should not supplement with phaseolamin.
Pregnant women are also discouraged from Phaseolus vulgaris supplementation because it is unclear if it is safe for developing and/or newborn babies. Also, do not use phaseolamin supplements if you have liver disease or are scheduled for surgery. Get a doctor’s opinion before beginning supplementation.
Diet and Exercise
It is important to note that Phaseolus vulgaris should not be used as a “panacea” carb blocker. In other words, you should not take White Kidney Bean extract and then think it means you can eat all the carbohydrates you want without any negative effects. A healthy diet is necessary to experience benefits from this supplement.
Choosing water-rich foods, exercising daily, drinking plenty of fresh water and managing your stress levels effectively will go a long way towards promoting weight loss. Using white kidney beans for weight loss is best thought of as an adjunct approach to healthy lifestyle modifications.
