Consuming vegetable soup a few minutes before a meal can increase feelings of satiety, leading to a reduction in calorie consumption of about 30%. The hot temperature of the soup heats the brain’s “satiety point,” reducing appetite. Additionally, the dietary fiber in the soup contributes to feelings of fullness in the stomach and intestines, leading to prolonged satiety. The liquids in the soup also fill the stomach, reducing food consumption.
A previous study found that consuming vegetable soup before a meal led participants to consume 120 fewer calories than when they didn’t have soup. If you don’t feel like making vegetable soup, a simple alternative is to mix half a cup of crushed tomatoes with half a cup of boiling water, add ingredients such as garlic, sucralose, dill, and onion chips, and heat the mixture in the microwave for a satisfying pre-meal soup.
Overall, consuming vegetable soup before a meal can lead to increased feelings of fullness and reduced calorie consumption, making it a beneficial addition to a healthy diet.
