Drinking maltose and soybean milk to lose weight may make you gain weight, because maltose syrup and sucrose are both carbohydrates. If you want to lose weight, you'd better drink pure soybean milk without sugar. There is a lot of sugar in the boxed soybean milk sold in the market, so it is basically impossible for you to lose weight by drinking soybean milk with sugar on the market, because drinking soybean milk with high calories every day will increase your calories.
People think that soybean milk can lose weight. It is necessary to drink pure soybean milk without sugar, because pure soybean milk has no added sugar and no food additives. Although it has calories, it will not be very high. Drinking some pure soybean milk in moderation every day can make your body absorb some nutrients and become healthier.
But even drinking pure soybean milk can't guarantee that you can help lose weight, because people's physique will change, so it's better to exercise on time if you want to lose weight.
