White kidney beans are rich in α -amylase inhibitors, which can inhibit the decomposition and absorption of carbohydrates, thus reducing calorie intake. Cactus is rich in dietary fiber, which helps to increase satiety and promote intestinal peristalsis. So the combination of these two ingredients can theoretically help to lose weight.
However, losing weight is not only achieved by reducing calorie intake and increasing satiety. Also need to pay attention to a balanced diet, control intake, proper exercise and many other aspects. Therefore, if you want to lose weight, I suggest you adopt a scientific diet and exercise plan, rather than relying solely on a specific food or drink.
