Kelly Clarkson Weight Loss: On The Plant Paradox Diet


Kelly Clarkson has always been open and honest with her fans. It’s one of the reasons she is adored by them (along with her amazing singing voice). So when she dropped 40 pounds, we knew she would tell all. And she did! 

The secret lies behind a diet based on The Plant Paradox, Dr. Stevrn Gundry’s best-selling book. It takes out gluten and other lectins, which are proteins in fruits, nuts, and vegetables. The Voice coach admitted to trying the lectin free diet last year due to an autoimmune disease and a thyroid issue. The change in her eating habits led to weight loss as part of a healthy, overall approach.

So, the weight loss wasn’t deliberate, as it came as a ‘side effect’ of controlling Kelly’s thyroid issues saying, ‘wasn’t about the weight, for me, it was I’m not on medicine anymore.

By focusing on her health, Clarkson had the added bonus of losing some weight! 

And we are here with all the details on how she did it! Check out her method, workout plan, diet, and everything else you need to know about Kelly Clarkson’s weight loss!

So, how did Kelly lose weight?

She used the book, The Plant Paradox, written by Dr. Steven Gundry to help her shed almost 40 lbs!

The book looks at, ‘how we cook our food, non-GMO, no pesticides, eating really organic,’ she told Extra. The diet can be restrictive, cutting out lectins that are present in a wide range of foods and whole grains. 

According to the book’s author, lectin acts the same way as insulin, which takes your body’s glucose for storage. So eating it can cause weight gain. 

In effect, the method does work to help you lose weight and focus on healthy and nutritious foods. This is exactly what Clarkson did! 

By following the diet in The Plant Paradox, Clarkson didn’t need to hire a trainer or follow an exercise regime. Instead, she focused on what she was fuelling her body with, and the results speak for themselves!

Kelly revealed, “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. I’m not on medicine anymore because of this book, it’s called ‘The Plant Paradox (by Steven R. Gundry, MD).’ It’s basically about how we cook our food, non-GMO, no pesticides, eating really organic… Literally, I haven’t worked out at all!”

Supplements Used

There are no indications to suggest she used supplements for weight loss. The inspiration for her weight loss and to follow The Plant Paradox was to step away from medication.

Country Living quotes Kelly as saying on Twitter, “Fake news that’s going around about me is that I’ve been taking weird pills 4 weight loss or doing weird fad diets.”

Instead of taking supplements, she focused on a healthy diet.

Kelly Clarkson Meal Plan

Kelly Clarkson’s meal plan is inspired by The Plant Paradox, a book that focuses on a low-carb diet! You can enjoy organic and GMO-free veggies on a diet, but there are a lot of restrictions.

Foods containing lectin, such as legumes, fruit, vegetables, and whole grains, are excluded due to the apparent link between eating them and inflammation (there is little scientific information to back this up). Gluten, which is present in barley rye and wheat, is just one type of lectin.

Consuming such food items can cause bacteria to enter the immune system and cause inflammation and the ‘leaky gut’ syndrome

The Plant Paradox Diet

“The Plant Paradox: The Hidden Dangers in ‘Healthy’ Foods That Cause Disease and Weight Gain”, authored by physician and former cardiac surgeon Steven Gundry, has helped celebrity Kelly with her thyroid issue and lose weight as a side effect. 

According to the book, consuming lectins can cause weight gain and many chronic diseases. 

But what are lectins? These are antinutrients found in grains, legumes, tomatoes, and eggplants. Lectins are toxins produced by plants for their survival, which cause inflammation, weight gain, intestinal damage, and other complications.

However, while it’s true that many of the foods we eat contain lectins, the author maintains that there is little evidence that supports that they are as harmful [1].

How do lectins cause weight loss then?

The author himself claims that he lost 70 lbs from his lectin free diet. The Women’s Health Magazine quotes him saying, “The amazing thing is when people change nothing except removing major lectins, they start losing weight and they still are eating lots of calories, but we’re not storing it as fat anymore.”

However, this contradicts the results of another study that shows that people who consume beans, lentils, and chickpeas (which have lectins) lost more weight than those who didn’t [3]. 

Therefore, there is still a lot of debate on this matter. There is a need for further studies to prove that lentils indeed help with weight loss.
