- Kelly Clarkson revealed the secret behind her weight loss in a new interview with Extra.
- Kelly attributes her weight loss and management of her thyroid condition to the book, The Plant Paradox, which urges people to cut out the lectins in their diets.
- Lectins, the book says, are "toxic chemical compounds" that promote inflammation throughout the body.
Now, it looks like she finally got the memo - and is revealing exactly what led to her transformation.
In a new interview with Extra, Kelly said that she's not working out, but has started eating better. "I literally read this book, and I did it for this autoimmune disease that I had and I had a thyroid issue, and now all my levels are back up," she said. "I'm not on medicine anymore because of this book."
That book she's referencing is called The Plant Paradox by Steven Gundry, M.D., and "it's basically about how we cook our food, non-GMO, no pesticides, eating really organic ... literally, I haven't worked out at all," she said.
Clearly this is working for Kelly, but what's The Plant Paradox about, anyway?
Gundry's a cardiac surgeon who says on his website that certain health foods like fruits and vegetables can harm your body by producing lectins, which he calls "toxic chemical compounds."
"When lectins invade our bodies, they can cause some serious inflammatory responses and other health issues, like leaky gut syndrome, weight gain, brain fog, and more," Gundry writes on his website.
His book provides a list of foods and ingredients that he says don't do this, including vegetables like broccoli and cabbage, along with fish and pasture-raised poultry. Fruits, however, are limited: only in-season berries and avocados get the green light.
So, can cutting out lectins help you lose weight?
Honestly, probably not any more than any other diet.
"The book is based on the premise that lectins in grains, beans, peanuts, and other plant-based foods are pro-inflammatory," says Julie Upton, R.D., co-founder of nutrition website Appetite for Health. "But there's no good evidence that this actually the case."
It should also be noted that a lectin-free diet restricts many, many foods that really are good for you, like whole grains, most fruits, and nuts.
There is strong evidence, however, that the healthiest people tend to focus on plant-based diets - lectins included - so it's tough to make a solid case that eating fruits and vegetables that contain lectins are going to harm you.
"I suspect Kelly Clarkson has lost weight by following an eating style that has fewer calories than what she was previously eating," Upton says. "When people lose weight, if overweight, they tend to feel better and most health biomarkers improve too."
Okay, but what about her thyroid condition?
Kelly didn't give details on her thyroid condition, or what medication she was taking for it. Treatment for hypothyroidism, however (an underactive thyroid and often the cause of weight gain) generally involves medication like synthetic hormones to alter thyroid levels, the Mayo Clinic says.
And while some doctors may prescribe an alternative medicine - specifically prescription-only natural extracts - in lieu of synthetic hormones, per the Mayo Clinic, it's not suggested that diet alone can manage thyroid conditions.
The bottom line: If Kelly's weight loss has prompted you to revamp your own diet, it's a good idea to focus on more plant-based meals - and to just ignore those "harmful lectins" for now.
