Try This French Onion Soup Diet Recipe For Blasts Belly Fat

Real-World Weight-Loss Success

California business owner Lisa Gemmiti, 57, doesn’t have time for complicated diets and isn’t willing to go hungry. Orsoni’s soup plan turned out to be the perfect approach for her. “It’s very simple, and you feel satisfied the entire time” she reports. “I lost seven and a half pounds and three inches of belly fat in a week. It works!” Pamela Goff agrees. She whisked off a full jean size and melted an astonishing 9 inches of ab flab in just seven days. “I had to re-measure myself because I couldn’t believe how much I’d lost” says the New Mexico mom and dental assistant, 55. “On the first day, I remember thinking, ‘This is too much food. I’m going to gain weight!’” New Jersey caregiver Latonya Nicholas, 44, was also stunned. “I weighed myself three times because I couldn’t believe the number. This plan is delicious and amazing,” Latonya shed 14 pounds in a week.

What You Eat on the French Soup Diet

To get weight loss off to a speedy start, you’ll eat Orsoni’s soup twice a day. Her recipe — which won raves from our diet testers — mixes classic French ingredients like onion and wine with powerful fat fighters like buckwheat, lean protein, olive oil, and turmeric.

According to landmark Penn State research, the way soup solids are suspended in broth confuses the body, triggering more stop-eating signals to our brains than any other type of food. “Soup will curb your appetite by at least 25 percent and up to 50 percent, so it takes a lot of the struggle out of eating less,” says Orsoni. The impact is so dramatic, one study found that women on the same diet shed 50 percent more weight simply by incorporating two bowls of soup a day, and they were testing soup with ordinary ingredients. Orsoni takes it to the next level.

Scientists from Harvard and around the world agree that the ingredients in Orsoni’s soup have extraordinary waist-shrinking power. Most — including onions, buckwheat, kale, garlic, turmeric, olive oil, wine — contain extremely high levels of flavonoid antioxidants. There’s exciting early evidence that these compounds suppress cravings, block fat absorption, improve blood sugar, speed metabolism, reduce obesity-driving inflammation and spike levels of gut bacteria that help make us effortlessly lean. There’s even research hinting that flavonoids activate SIRT1, a gene that burns so much fat, it’s been nicknamed the “skinny gene.” Orsoni says “I call this my Super Weight Loss Soup, with good reason.”

Soup Diet Ingredients

  • Onions: They’re “rich in quercetin, an antioxidant that boosts metabolism and prevents fat accumulation,” says Orsoni, who has LSU research to back her up.
  • Buckwheat: This grain’s huge load of fiber fights hunger and blocks calories; meanwhile, it’s high in a skinny-gene-activating antioxidant called rutin. “It’s a miracle grain because it makes a big difference so quickly,” Orsoni says.
  • Kale: “French research has shown that the high folate content in this leafy green helps increase weight loss, principally in the waist,” notes Orsoni.
  • Turmeric: Preliminary Tufts University research hints that turmeric may block the formation of new fat — and may even speed burning of existing fat.
  • Miso: A soup base made from fermented soy, miso activates skinny genes and contains probiotics — beneficial bacteria linked to natural weight loss.
  • Tomato paste: Concentrated cooked tomatoes provide lots of lycopene, an antioxidant that increases the release of metabolism-revving hormones by 25 percent, per Taiwanese researchers.
  • Mushrooms: Experts say powerful mushroom compounds improve blood-sugar control — a factor that reduces levels of insulin, a hormone that stores excess sugar as belly fat.
  • Olive oil: Not only is the stuff rich in nutrients linked to weight loss, but university studies show it helps us absorb significantly more fat-fighting antioxidants from veggies.
  • Wine: Lab testing at Oregon State University found that compounds in red wineappear to slow the formation of new fat—and may even block some fat entirely.
