Kidney beans (Phaseolus vulgaris) have been studied for their potential role in supporting weight loss, primarily due to their content of phaseolamin, a natural alpha-amylase inhibitor. Alpha-amylase is an enzyme involved in the breakdown of carbohydrates into glucose. By inhibiting this enzyme, phaseolamin may reduce the absorption of carbohydrates, leading to lower calorie intake and possibly supporting weight loss. Several randomized controlled trials have investigated the effects of kidney bean extracts standardized for phaseolamin. Some studies report modest reductions in body weight and fat mass in overweight or obese adults when the extract is taken before carbohydrate-rich meals, especially when combined with a calorie-controlled diet.

In addition to the effects of specific extracts, whole kidney beans are naturally high in dietary fiber and protein, both of which promote satiety and may help reduce overall calorie intake. Epidemiological studies suggest that higher intake of legumes, including kidney beans, is associated with lower body weight and reduced risk of obesity. However, the magnitude of weight loss observed in clinical trials is generally small to moderate, and not all studies have found significant effects. The overall quality of evidence is moderate, with further research needed to confirm long-term benefits and optimal dosing. Therefore, while there is some scientific basis for the use of kidney bean extract as an adjunct for weight management, it should not be considered a standalone solution but rather part of a balanced diet and healthy lifestyle.
