I can definitely say that it has the function of losing weight, but at the same time, I also want to emphasize that persistence is the most important thing. You can't eat today and forget. Cucumber contains a substance called propanol diacid. This substance can inhibit the conversion of sugar into fat. Tomatoes are low in calories and rich in cellulose. So is celery. Besides, I also suggest that you exercise, because the effect of losing weight simply by food is limited.
