How weight-loss soup helps you shed pounds

You’ve probably heard about or even tried a wacky old soup fad (looking at you, cabbage soup diet!). The new way to use soup is both very different “and so much better,” says Nisha Patel, MD, director of an obesity program at Sutter Health California Pacific Medical Center. Basically, instead of using soup to cut calories to unrealistic levels, you use higher-protein soup to make slimming habits highly sustainable.

Dr. Patel loves making soup in her Instant Pot: “I joke that it’s the best medical intervention I’ve come across to improve eating habits.” She even “prescribes” soup rich in fiber and protein to help patients reach a healthy weight and stay there.

4 superpowers of soup for weight loss

A big bowl of broth-based soup easily contains 500 fewer calories than a typical homemade meal and 1,000 fewer than takeout. Other ways it helps get you lean:

Potent appetite control

In a Penn State study, women were served either chicken soup or chicken casserole made with identical ingredients. Then they went to a buffet. The soup group automatically ate far fewer calories. Why? “Water bound with food, as in soup, has been shown to have a significantly greater effect on hunger-control mechanisms,” says study author Barbara Rolls, PhD.

Easy protein-maxxing

Protein is extremely easy to load into soup. “And it’s the most satiating nutrient by far,” says Ted Naiman, MD, author of Satiety Per Calorie. So soup with lots of protein helps further reduce total calorie intake without effort. Protein also helps protect metabolism-boosting muscle. It can even make exercise feel easier. To optimize weight loss, “around 30 grams per meal is a good general target,” says Dr. Patel.

A psychological edge

“Soup is comfort food,” says Dr. Patel. It makes us feel good, not deprived. On top of that, a meal-sized serving is visibly much larger than other meals with similar calories. It’s a cue to our brains that we have plenty to eat, which Rolls says is another reason soup helps us make better choices with less struggle.

Make-ahead magic

Millions of us default to fast food when we have a bad or exhausting day, mostly because we don’t have the energy to make anything. But when you have a variety of yummy, comforting soups in your fridge and freezer, it can be a game changer.

How to make weight-loss soup work for you

Start with any reasonably healthy soup you like, adding extra protein if needed to hit 30 grams per bowl (the amount in ½ cup shredded chicken). Find nutrition facts at the bottom of recipes or ask ChatGPT to help. Freeze leftovers in single-serve containers, building a stash of heat-and-eat options. Enjoy soup as often as you like.

What else should you eat? Soup can enhance virtually any dietary pattern. Just go easy on processed foods, which can override soup’s appetite-suppressing effects. If the scale is moving in the right direction, you’re all good. But if you aren’t seeing results, use a free app like MyFitnessPal to track food and get a better sense of the right portions for your body. Dr. Patel also encourages you to stay active and add strength training to your routine two to three times per week. It’s a formula that worked wonders for Stefanie.

Weight-loss success: How Stefanie lost 4 sizes with soup

Juggling mom duties and a bustling business, Stefanie’s weight crept up, and she often found herself winded. Yes, she tried eating better. It didn’t help, and she was too tired to do much else. Then a minor surgery went awry. “I could barely walk or breathe for weeks,” she recalls. She blamed being out of shape—and vowed to change.

Stefanie joined a group fitness class, where a trainer suggested aiming for over 30 grams of protein per meal. Since she was juggling more than ever, she searched for easy slow-cooker meals that were healthy and protein rich. “That’s how I started making soup!”

How did soup help her? “I have a thermos that keeps soup warm all day, so I could keep it in my car to eat on my way home from a job,” she says. “For me, once I’m hungry or tired, something in my brain switches. I need the healthy option to be right there or I’m not gonna make a good decision.” Eventually, new family faves like lasagna soup, enchilada soup and chicken corn chowder even replaced takeout after kids’ sport events. This alone has saved her tens of thousands of drive-thru calories.

Batch Cooking: The secret to sticking with it

“If I’m making a casserole, I’ll also make soup in the Crock-Pot at the same time,” she says. “I only cook a couple nights, but have everything I need all week. I think it’s the biggest thing I’ve done to help me succeed.” And succeed she has. “I immediately was sleeping better and felt my anxiety going down. Within three months, my clothes fit better,” says Stefanie.

By four months, everyone could see she was transforming. In a year, she lost 30 pounds and went from a size 14 to a 6. “I feel like I’ve kind of aged backwards. Everything has improved drastically.”

Stefanie lost 4 sizes

“Soup is so comforting and nourishing, I actually prefer it to a lot of the less-healthy food I used to eat,” Stefanie shares. Has she given up burgers and pizza? Not at all. “I just make sure that when I have an indulgent meal, I have time to sit down and enjoy it.” Another big change that she partially credits to soup’s appetite-suppressing effect: “I used to eat constantly. No matter how much I ate, I was always hungry. Now I just require much less food to feel satisfied.” She ended up losing four sizes—no crazy diet needed!
