9 celebrities who love the keto diet

The keto diet is not for the faint of heart. 

The diet has gained major traction in the wellness world and is lauded by everyone from athletes to actresses for its reported health benefits, including weight loss, lower blood sugar and lower blood pressure. By following the strict low-carb, high-fat diet, your body will enter ketosis, the metabolic state that burns fat instead of carbs.

Celebrities who love the keto diet

Halle Berry 

The 53-year-old mom of two took to Instagram last year to talk about her love of the keto diet and its effect on aging. Berry reportedly relies on Maria Emmerich’s best-selling keto cookbook. 

She said:

"Keto is a very low-carb food plan which actually forces your body to burn fat like crazy. I also believe it’s been largely responsible for slowing down my aging process. The keto lifestyle offers so many benefits such as weight loss, (moms that’s how we get rid of our baby bellies), appetite control, more energy and better mental performance. If you’re like me, you can possibly reverse type 2 diabetes, you’ll experience better physical endurance, better skin and also less acne if that’s an issue. And it even helps control migraines!"

Tim Tebow

The quarterback-turned-baseball player revealed he was on the keto diet a few years back to keep him in shape.

Revealed the athlete to GQ in 2017: "I'm on something called a ketogenic diet which is high fat, moderate protein, low carb, low sugar. So I have to take in a lot of fat, and the number one fat comes from avocados. It's incredible. It's a superfood. And even if that's not your diet, it's incredible food for you."

One essential superfood in the Mets player's keto diet? Avocado: Tebow estimates he consumes at least four a day.  

Vanessa Hudgens

The actress regularly shares footage of her workouts and post-workout snacks to her 35 million (!) Instagram followers and has taken to interviews to discuss her diets. While she has spoken out in support of intermittent fasting, the High School Musical star also alternates with the keto diet. 

She said to People in April:  “If you have the right ingredients to keep you on track, I think it’s amazing. People a lot of times think of fats in diets as a negative thing, and when you’re doing keto it’s a very positive thing. I’m always making sure I’m getting those healthy fats in, so I eat a LOT of almond butter. You feel really energetic and supported on the keto diet.”

Vinny Guadagnino

The Jersey Shore star is such an advocate for the diet that he even dedicated his Instagram name to "Keto Guido" and is releasing a cookbook in September with the same name

"I’ve discovered the fountain of youth," he began in a shirtless Instagram post last spring. 

"When I ate sugars and grains I was 50lbs heavier and looked 10 years older. I look around and feel sad and angry for the majority of the population who are overweight and obese that have been taught to eat grains, use “healthy” margarines and oils, drink diet soda with artificial sweeteners, and stay away from saturated fats. This is why I started this page," he continued.  

Kourtney Kardashian

The eldest Kardashian sister was reportedly first introduced to the diet in 2017 after doctors found high levels of mercury and lead in the system. Kourtney detailed her experience with it earlier this summer and why she was back on the diet. 

"My body never looked better than when I did the keto diet two and half years ago, when I did it for two months. In my experience, I’ve found the best method to train my body to curb sugar cravings, burn fat, and kick-start weight loss is by sticking to a keto diet," she penned for Poosh's website

She continued, "I had a really positive experience the last time around and wanted to restart my routine this summer. It’s definitely a more restrictive eating plan, but I found that once I knew the ground rules, I was very strict and really stuck to it. My plan this time is to eat minimal carbs and no grains, beans, or legumes. I’m focusing my meals on fresh vegetables and lean proteins. I eat three meals a day with no snacking in between if possible."

Alicia Vikander 

The Academy Award-winning actress teamed up with trainer Magnus Lygdback (clients include Mark Ruffalo, Gal Gadot and Alexander Skarsgard, amongst other stars) to get in shape for the action film Tomb Raider. Lygdback got Vikander in tip-top Lara Croft shape by exercising up to seven days a week and, you guessed it, the keto diet. 

"It was a high-fat, no-carb diet — not even low-carb," he said in an interview with PopSugar. It's always tricky the first couple of days, but [Alicia's] willpower is just unbelievable, and she didn't complain, even though I could see she was struggling a little bit. She kept on bringing it every day."

Mama June 

The "Honey Booboo" star, whose real name is June Shannon, made headlines back in 2017 after losing 300 pounds after undergoing a gastric sleeve surgery. Though she gained some pounds back due to other health issues, the 40-year-old revealed to BUILD Series that the keto diet has helped her maintain her weight. 

"It's not that bad," she said during the interview. "It's like cheese, eggs, protein, meat, and you honestly lose weight with that. That's what I've been going back to and it actually really works."

Al Roker

The anchorman opened up with his experience on the keto diet to TODAY back in January, explaining he's seen "great" improvement with his blood pressure and cholesterol.

He also stresses the need for patients to consult their doctors before going on the diet, saying:

"There's science on both sides that says it's not a great idea and science that says it is a great idea.I think it's up to people, with their doctor, with their medical professional (to make their own decision)."


Jenna Jameson 

The adult film actress has been a staunch supporter of the keto diet, taking to Instagram in November to reveal how she lost 80 pounds after giving birth to daughter Batel. 

"I have absolutely never felt better! she shared on Instagram in May. "Combining #sobriety, the keto lifestyle and intermittent fasting is the perfect trifecta for me when it comes to a healthy sustainable fitness journey."


While the diet isn't for everyone and has caused a fair share of controversy amongst health professionals and trainers -- Al Roker recently got into a tiff with trainer Jillian Michaels about its benefits -- high profile names such as Halle Berry and Tim Tebow have relied on the keto diet to whip them into shape.
