The Kate Middleton diet has everyone curious about the secrets behind the duchess’s slim figure. Considering that the Duchess of Cambridge maintains an impressively fit physique at virtually all times, there’s little mystery behind why people want to find out what Kate Middleton eats. As one might expect, there’s not one magical Kate Middleton diet menu that you could browse like a list of restaurant offerings. Like most folks, her eating habits change quite a bit from time to time, based on what’s happening in her life at that moment.

The duchess has been said to be an incredibly disciplined eater who favors healthy food over junk. (Anyone surprised? Yeah, neither are we.) However, the specific type of healthy food she eats varies depending on what personal experience she’s going through, as well as what’s happening in the environment surrounding her.

Good news: We have the scoop on just about all the Middleton diet secrets.

The Kate Middleton Wedding Diet

Like many brides, the duchess wanted to look slim in her gorgeous gown on her big royal wedding day when she married Prince William back in 2011. Of course, with millions of people in the world tuning in to watch her get hitched, the stakes were considerably higher for her to look trim. So how did Kate Middleton lose weight for her wedding? It’s not surprising that she reportedly opted for the Dukan diet leading up to the big day. The opposite of a longevity diet, the Dukan diet is a high-protein, low-carb French diet favored by many Hollywood celebs, among them Jennifer Lopez. As you can imagine, it’s pretty hardcore.

The Dukan diet involves four stages: attack, cruise, consolidation, and stabilization. In the “attack” stage, you have to eat only protein — no fruits and not even vegetables — for four to six days. Next, in the “cruise” phase, you are allowed vegetables on some days.

Then, the “consolidation” phase brings back some fruits, carbs, and cheese, along with two “celebratory” meals a week. How long phases two and three last depends on how much weight you want to lose. Then, for the rest of your life, you do “stabilization,” which requires doing the “attack” mode once a week.

(By the way, if this is sounding more like boot camp to you than a duchess diet, you’re definitely not alone!)

The Kate Middleton Pregnancy Diet

As many Kate Middleton fans know, the royal suffered from extreme morning sickness and food aversion while she was pregnant with her first two children, Prince George and Princess Charlotte. Sadly, the poor thing also struggled with hyperemesis gravidarum — the scientific term for severe nausea, vomiting, weight loss, and electrolyte disturbance during pregnancy — with her third pregnancy. Thankfully for her, there was a tasty solution to her health issues available.

Sticking to a diet of hearty-yet-healthy foods like avocados, berries, and oatmeal helped Kate Middleton put on a sufficient amount of weight during her first two pregnancies, despite getting sick all the time.

She never revealed whether she ate the same exact foods during her third pregnancy, but it wouldn’t be shocking if she repeated the successful meal plans that worked for her in the past. What we do know is that she did try something new — ginger — in order to combat morning sickness. Studies have shown that ginger is a safe and effective means of fighting nausea during pregnancy, so it’s not surprising that she gave this age-old remedy a go. We hope it gave her a much-deserved helping hand!

What does Kate Middleton eat to get gorgeous skin?

Even after Kate lost weight following the birth of Prince George, she reportedly wanted to reap more health benefits from her diet. She allegedly embarked on an ambitious regimen that involved eating only raw foods at least one day a week.

It includes the beloved Latin American dish ceviche, or raw fish that is marinated generously in lemon or lime juice and spices. It also involves eating dishes like watermelon salads, gazpacho, goji berries, and tabbouleh. The idea behind this diet is not only to stay fit, but also to keep the skin looking clear and healthy, since raw food often contains higher levels of vitamins and nutrients than cooked foods. Though this specific Kate Middleton diet wouldn’t be our first choice, we have to say that it sounds a lot more doable (and enjoyable) than the reported wedding and pregnancy diets.

Just because she eats simple, healthy meals most of the time doesn’t mean Kate Middleton isn’t up for a challenge every now and then. Case in point: When she and Prince William visited a food and wine festival in British Columbia during their Canada Royal Tour in 2016, she bravely tried a “geoduck,” a giant clam with a crazy long neck. As evidenced by the photo below, this dish is not for the faint of heart.

And to top it off? She also sampled a blackcurrant liqueur at the same event. Daring!

Although geoducks might not be a staple food in Kate Middleton’s diet, she does enjoy a nice serving of seafood from time to time. Prince William recently revealed while visiting a Japanese restaurant that both he and his wife are fans of sushi. That said, Kate Middleton’s tastes are often reported to be a bit more bold than her husband’s, according to HELLO! magazine.

The duchess apparently loves a variety of spicy food — especially curries — but Prince William tends to struggle a bit with hotter meals. (We give him props for being brave enough to try them, though!)

Other than sticking to her basic healthy choices of raw vegetables and fruits, plus lean sources of protein, the duchess has also developed a love for cooking homemade meals over the years, particularly vegetable curries.

The best part about a Middleton home-cooked meal? When she’s visiting her family’s home, they all eat dinner together at the kitchen table, just like the good old days. Aww!

But when she’s making food for herself, she’s clearly all business — in the best way. According to Marie Claire UK, the duchess enjoys mixing spirulina powder in her morning kale, spinach, lettuce, cilantro, and blueberry juice smoothies. Spirulina, which is a blue-green algae, adds a gold mine of health benefits because it’s chock-full of vitamins, minerals, proteins, and antioxidants. It’s known to boost the immune system, fight off infections, and protect against allergic reactions — wow!

What foods does Kate Middleton hate?

One cafe found out the hard way that the duchess is definitely not a fan of almond milk. In January 2018, she visited this cafe — which is run by a charity — with her husband, and had a very unexpected reaction when she was offered the beverage. “We put almond milk on the table because we had read that she had it,” said Kim Gardener, who runs Betel UK’s women’s houses. Kate responded, “Don’t believe everything you read — I don’t even like almond milk.”

Yikes! Considering how rare it is for the royal to say something so unscripted like that, we’re guessing she really can’t stand it.

The Carole Middleton Diet: One of Kate’s Inspirations

Kate Middleton’s mom, Carole Middleton, has reportedly been a big inspiration for her famous daughter and her eating habits over the years. Judging by how svelte and healthy she looks all the time, that’s not surprising to us.

Carole’s brother, Gary Goldsmith, shared on his blog: “Carole has always looked after herself and eaten healthily and she has a stunning figure, and that mentality of considering your diet and exercise is evident in [Kate and Pippa] also.”

Goldsmith further elaborated how his 63-year-old sister Carole looks “phenomenal for her age” and how his nieces are following in her footsteps: “They eat healthily, they play sports, they keep themselves incredibly active.”

Although Carole has not gone into too much detail about what she eats on a regular basis, she did reveal that the Dukan diet helped her lose weight ahead of Kate’s wedding to Prince William back in 2011. Reportedly, she calmed her cravings with “cottage cheese and prawns.”

Wow! If that’s all it took for her to remain disciplined, then clearly the apple doesn’t fall far from the tree!

Does Kate Middleton eat indulgent or sweet food… ever?

Now here’s the part where things finally get fun! During the holiday season, especially Christmas, the duchess lets just a bit loose with the epic royal feast. On the menu? Roasted turkey, ham, parsnips, mashed potatoes, and Brussels sprouts. Yum!

Oh, and don’t worry, we didn’t forget dessert. Sweets served during Christmas include British favorites like scones and fruitcake. But what’s Kate’s holiday treat of choice? Sticky toffee pudding.

But is Christmas the only time when Kate Middleton indulges? Not exactly! She’s been spotted on rare occasions eating common snacks like popcorn while out and about with her husband, especially when they’re watching sporting events. She’s also known to enjoy a nice glass of wine on occasions. For example, while traveling New Zealand, she got the chance to sample a variety of different wines, including Pinot Gris and Riesling.

Now, this is a woman with good taste — literally!
