Pea soup offers you a comforting way to fill yourself up with minimal calories; however, a pea soup diet falls within the same fad diet category such as the Cabbage Soup Diet. Losing weight by including pea soup to meet your dietary requirement can be a sound weight loss strategy, provided you also limit your caloric intake to create a calorie deficit.
The peas used to make pea soup count as both a meat and a vegetable, as peas contain a substantial amount of protein per serving. Traditional pea soup combines water, dried split peas, ham, onions, carrots, celery and seasonings to create a thick, rich soup, according to the "Betty Crocker Cookbook." The carrots, onions and celery contribute to your 2 cups of vegetable requirement, and the seasonings add no calories. When losing weight, omit the ham as 2.5 oz. of diced ham has 85 calories, which makes it a higher calorie addition to the soup.
Calories and Nutrients
Pea soup without ham contains about 190 calories per 1 1/2 cups, according to Michigan State University. The soup gives you 13 g of protein, or about 30 percent of a woman's needs and 23 percent of a man's requirements. The trace of fat means you have room in your diet for other healthy fats from olive oil or nuts, and the 13 g of fiber keeps you full long after you eat the soup. You get about 70 percent of your vitamin A requirement in 1 1/2 cups, 10 percent of your iron needs and small amounts of vitamin C and calcium.
Protein helps you lose weight because it satisfies you, helps you burn calories and aids with reducing fat in your body, according to a study published in the May 2011 issue of "Nutrition Metabolism, and Cardiovascular Diseases." Both plant proteins, such as those in pea soup, and animal proteins help reduce body fat. Additionally, the Centers for Disease Control and Prevention recommends replacing meat or refined grains with a legume such as peas to help you eat fewer calories and still feel full. The physical act of eating soup takes longer than consuming a serving of meat or a slice of bread, which helps you eat more slowly, and allows your stomach to send a "full" signal to your brain.
Eating pea soup several times a day may cause you to experience boredom because of the lack of variety, and the high amount of dietary fiber can cause intestinal discomfort. Eat the soup for lunch or dinner, and choose other low-calorie foods from the fruits, whole grains and fat-free dairy groups for your other meals. For a sodium-free pea soup, make your own soup from dried peas rather than relying on canned pea soup, which often has excessive sodium.
