White kidney beans are simply too hot recently, right, and many people are claiming that it is a great tool for fat loss. A lot of babies, but also said to eat hot pot to eat a big meal before eating some white kidney beans, you can rest assured that feast, do not have to worry about the problem of long meat. I'm really speechless ah, can not help but online to dispel a rumor.

White kidney beans are a kind of vegetable beans, also known as common beans, originated in South America. White kidney beans are rich in protein (22-27% of seed weight) and carbohydrates (39-47% of seed weight) and have high levels of bioactive compounds such as peptides, among them alpha-amylase inhibitors (cauliflower proteins), polyphenols, oligosaccharides and lectins.

It is said that white kidney beans can lose weight, mainly because the alpha-amylase inhibitors (Cauliflower protein, Cauliflower protein) can reduce the activity of amylase in the body, reduce part of the amylase ability to digest carbohydrates, to play a role in weight loss.

Alpha-amylase inhibitors, as an all-natural bioactive substance, are found in the endosperm of many plant seeds. However, white kidney beans contain higher levels of a-amylase inhibitors than other beans, so white kidney beans are often used to extract a-amylase inhibitors and have come to be known as "white kidney bean extract".

Does alpha amylase inhibitor really work?

Theoretically, no: it prohibits the body from breaking down starches into sugar, reducing energy conversion and forcing the body to break down fat for energy.

Let's take a look at the experimental data.

1In one of the trials, overweight individuals were given 3,000 mg of white kidney bean extract daily and consumed a carbohydrate-rich but calorie-neutral diet compared to a control group, and after eight weeks, the experimenters who used the white kidney bean extract lost an average of 3.8 pounds, while the control group lost only 1.65 pounds, a difference that made a difference but not a significant one.

The results showed that there was no significant difference though compared to the control group. However, for the individuals with the highest intake of high carbohydrates, the experimenters taking the white kidney bean extract significantly lost weight and waist circumference.

NOTE: All of the above trials had amylase inhibitor intakes of ≥1 g of white bean extract.

From the data of these studies, it appears that white bean extract is indeed effective in reducing body weight and waist circumference in obese individuals on a high-carbohydrate diet.

However, all effects are based on dosage, which is standardized based on scientific clinical trials.

The U.S. FDA and Health Canada strictly state:

White kidney bean extract, when used for weight management, is to be used in a dosage of 1g (1000mg) before a meal, and the units of activity of the amylase inhibitor in each gram should be 3000 u/g.

That is to say that less intake is essentially ineffective.

And it's impossible for us ordinary people to try to consume adequate amounts of alpha-amylase inhibitors by eating white kidney beans.

Secondly, the active ingredient in white kidney bean extract is alpha-amylase inhibitor protein, and yes it's a glycoprotein, which means that prolonged high temperatures will inactivate him, whereas our normal dietary cooking will completely destroy the activity of alpha-amylase inhibitors.

And then there's the fact that white kidney bean extract only has a starch blocking effect! That is to say, you eat into the rice, noodles, steamed bread, potatoes and other staple food white kidney bean extract can help you block 66% of the energy intake, but on the protein, fat, sugar intake is not effective.

Finally, to summarize: eating white kidney beans is not able to lose weight, but the extract of white kidney beans for high-carbohydrate diet structure of obese people, it is indeed effective in reducing the weight and waistline. Of course users should pay more attention to the content of the active ingredients to avoid blind use.
