Salad, Soup, and Success

Salad, Soup, and Success

Jeff Novick, MS, RDN

A concern I often hear is that people can’t follow my dietary recommendations because they think large quantities of salad are required as a way to successfully incorporate the principles of calorie density, which are important for both weight loss and weight maintenance.  They say consuming such large amounts of salad takes too much time, too much money, and/or may cause digestive issues. Too often, this leads them to conclude that the principles of calorie density cannot be helpful to them.

Setting the Record Straight on Salad

Salads are not required for success.  They can be very time consuming and expensive, which are often key issues for many. All of the time, energy and money spent on salads is not only unnecessary, it may not the best way to incorporate veggies into your daily diet. (The same applies equally to raw vegetables.)

While adding vegetables to a meal lowers the overall calorie density and is an important part of my recommendations, salad is not required. In fact, when we look at the research on this, the form of vegetables that lowered overall calorie density the most and was the most filling was not salads, but vegetable soup. (See references 1-9 below.)

Practical Tips on Soup

Soups can work in many ways, the same as you may be using raw veggies and/or salads in applying the principles of calorie density. Here are 3 simple tips:

  1. Soups can be an effective pre-load to a meal:

Soups filled (mostly or entirely) with non-starchy vegetables can reduce the overall calorie density of a meal if consumed before the meal as a “pre-load.”  Studies have shown that salad pre-loads reduced the overall calorie density for the meal by 7% for a smaller salad and 12% for a larger one (5), while soup preloads lowered the overall calorie density of the meal by 20% (4).

  1. Soups can lower overall calorie density of the meal:

To help lower the calorie density of a meal, I recommend that up to 50% of your meal (by visual volume) be non-starchy vegetables. Soups can be effectively used for this strategy.  For example, have a bowl of vegetable soup with a plate or rice and beans.

  1. Soups can be the main meal:

Soups can also be the main meal. If they are main meals, make sure you make them hearty and also include plenty of starches (legumes, pulses, intact whole grains, starchy vegetables) in the soup.

Success!  

After I posted this on the McDougall 10-Day Program FB page, someone added, “One of the big advantages I see to taking this route, is that it totally bypasses the excuse of ‘I can’t find a salad dressing I like.’ Or in my personal case, ‘I cannot tolerate the items often recommended, such as lemon juice and vinegar.’”

With fall coming, this is a perfect time to incorporate warm, satiating soups into your lifestyle.  They can be inexpensive, quick to prepare and soothing.  So, if you are struggling with the time or the expense it would take to include large amounts of salads and raw vegetables, try a big bowl of vegetable soup instead.

In Health,

Jeff
