‘It’s a Miracle!’: ‘Wheat Belly’ Author William Davis, MD, Reveals His Happy Hormone Fat-Loss Secret
Forget Ozempic! Dr. William Davis reveals how a 'love hormone' reset helped Jodi, 75, lose 35 pounds
Wheat Belly diet author William Davis, MD, has a new book out called Super Body. In it, he shares a fresh way for women to blast fat and boost mood. And it centers on the feel-good hormone oxytocin. His advice worked for Jodi, 75, who now weighs less than she did in high school! Here, the trusted cardiologist and New York Times bestselling author explains how his happy hormone diet can help you lose weight and feel great!
Why Dr. Davis is focusing on the hormone oxytocin
You’ve likely heard about oxytocin, the natural bonding hormone in the brain. It gives us a fleeting feel-good high after we hug a loved one or cuddle a pet. But Dr. Davis says emerging science reveals this hormone can also play a major role in where our body fat is stored. And that concept may change the future of weight loss.
How is oxytocin connected to weight loss?
“Oxytocin is primarily known as the hormone of love, but it is also the hormone of body composition,” says Dr. Davis. Scientific evidence can be found in the journal Nature. And although Dr. Davis is still working on human trials, he can extrapolate some powerful findings from his preliminary studies.

Boosting oxytocin begins in the gut, where trillions of “good” bugs reside. “The idea that we can restore a microbe to the human GI tract that then triggers your brain to release a steady stream of oxytocin—that’s revolutionary,” he says. “Science has evolved. It’s telling us there are smarter, safer ways to reshape your body than conventional dieting.”
The ‘Wheat Belly’ doctor shares his new weight-loss strategy
Dr. Davis’ book Super Body reveals a new strategy for tapping into the power of oxytocin. Don’t rely on temporary hormonal blips from a quick hug or kiss. “Strive for around-the-clock boosts in oxytocin that we get by restoring proper bacterial microbes now missing from our guts.”
In other words, keeping your gut healthy can fuel your weight loss. “It’s not diet, exercise or pharmaceuticals, but the microbes in your intestinal tract” that make a difference in your waist size, says Dr. Davis.
5 ways Dr. Davis’ new 3-week plan can help you
It reduces hunger
While on this plan, you never have to limit food quantities. You may even eat less, says Harvard research. Dr. Davis explains, “An increase in oxytocin turns off our interest in snacking.”
It builds muscle
“Oxytocin works to restore youthful muscle mass and strength, while helping shrink abdominal visceral fat,” Dr. Davis encourages. That’s key, since women lose about 30 percent of their muscle as they age, a change that slows metabolism. And the loss can be amplified by GLP-1 medications.
It mends a leaky gut
A weakened gut triggers inflammation and weight gain, causing toxins to spill into the bloodstream. But boosting oxytocin can help halt it.
It rekindles youthful skin
“Oxytocin is also the hormone of youthfulness, as it smooths wrinkles by restoring facial muscles—no ‘Ozempic face.’”
It helps you feel more peace and joy
Oxytocin dials down levels of the stress hormone cortisol, which is known to trigger belly fat.
How to follow the ‘Wheat Belly’ doctor’s new plan
Avoid these foods: Avoid gut-harming foods like wheat by going grain-free. Also, dodge blood-sugar spiking ingredients like added sugar and high fructose corn syrup.
Eat these foods: Build meals using protein, healthy fat and low-starch veggies. Enjoy eggs, steak, salmon or pork chops cooked in butter and olive oil to satisfy hunger; serve with green leafy veggies.
Favor fermented foods: Also, reach for fermented foods like kefir, kombucha and sauerkraut to support your gut. One of Dr. Davis’ top ways to reseed the gut is to increase body stores of the bacteria Lactobacillus reuteri. His go-to method: using his homemade fermented “yogurt” recipe here.)
Don’t forget connection: Continue to do the normal things that create microbursts of oxytocin. Cuddle a grandbaby, pet a kitten, get a massage, laugh with friends or perform an act of kindness.
How big a difference can these tweaks make?
“The effect is huge,” says Dr. Davis. One test case lost 100 pounds and another, Susan, 78, calls the fermented yogurt “an age-reversing drug.” Plus, Natalia lost 40 pounds and relieved her chronic pain, fatigue, allergies and skin rosacea.
Success story: Jodi lost 35 pounds!
After Jodi Geoffroy followed a nutritionist’s advice to eat more sprouted bread, she began having severe IBS symptoms from the grains. “I needed a bathroom all the time,” she says. “I worried, am I not going to be able to go anywhere anymore?” Then Jodi turned to Dr. Davis’ advice to try to correct her health problems. She avoided sugar and grains and made his gut-friendly yogurt and his fermented sparkling juices.
“The weight was falling off.” In all, Jodi melted away 2.5 inches in her waist and dropped 3 jean sizes. And her digestive complaints improved by 80 percent.
Now she tells people, “You don’t need GLP-1s. Just give up bread!” She adds, “I have as much energy as I did 20 years younger. At 75, I’m not on any medications. And people say my skin looks beautiful. I weigh less than I did in high school!”
Jodi says, “It’s a miracle! My health is so much better.” Her prediabetes and chronic digestive woes went away. And she sleeps more soundly now. About giving up bread: “I agree it’s hard, but it’s worth it to lose 30 pounds and look and feel good!”
Try Dr. Davis’ 2-ingredient skinny gut-friendly ‘soda’
This sparkling gut-healing beverage contains a powerful probiotic to help prime the microbiome for weight loss. And while juice is high in sugar and can stress the gut, the “good” bacteria here eat the sugar during the fermentation process.
Ingredients:
-1 capsule S. boulardii CNCM I-745 probiotic (like Florastor brand) or 1 ⁄4 cup kombucha
-1 quart (32 oz) natural fruit juice without preservatives or added sugar
Directions:
Pour juice into a glass container and empty the contents of the capsule into the juice. Close the lid and lightly swirl. Loosen the cap to avoid exploding from gas/bubble build-up. Allow to ferment at room temperature for 60 to 72 hours (becoming less sweet the longer it sits). Enjoy 1 glass (4 to 8 oz) a day. Drink as is, with ice, or dilute after fermenting with filtered water. Serves 4 to 8.
