Queen Elizabeth II isn’t just the United Kingdom’s longest reigning monarch; she’s the oldest head of state in the world. And at 92 years old, she surpassed the average life expectancy for women in the UK by almost a decade. While her status undoubtedly gives her unparalleled access to the best doctors, chefs, and ingredients, she’s also known to have a surprisingly simple approach to food and nutrition. Here’s what you can learn from Her Majesty’s healthy eating habits.

Keep your portions in check

Former palace chef Darren McGrady told RecipesPlus that, unlike Prince Phillip who “lives to eat,” Queen Elizabeth sticks to small portion sizes, preferring four light meals instead of three larger ones.

If you’ve ever tried to lose weight, you know how important portion control is for your waistline: University of Cambridge researchers estimate that smaller packages and portion sizes could help us cut our daily food consumption by about 25 percent, and according to a report from the McKinsey Global Institute, reducing portion size is the most effective way to fight obesity.

Indulge in your favourite things, not in everything

For Queen Elizabeth, that means eating every slice of chocolate biscuit cake. "She'll take a small slice every day until eventually there is only one tiny piece, but you have to send that up, she wants to finish the whole of that cake," McGrady said. As for other types of cake? The staff can eat the leftovers.

Research shows that treating yourself is an important part of a healthy, long-lasting diet. One Israeli study found that people who start their day with chocolate, cookies, or ice cream may be better able to manage cravings long-term. “Cravings increase on a low-carbohydrate diet, so it’s better to incorporate them in a healthy way,” says Dr Daniela Jakubowicz, author of the study. Jakubowicz suggests treating yourself in the morning for the best results; her other research shows that a hearty breakfast is more beneficial to weight loss than a heavy dinner.

Even better if it’s dark chocolate

The Queen likes her chocolate 60 percent or higher, reports Business Insider. "It has to be the dark chocolate, the darker the better,” McGrady confirmed. “She wasn't keen on milk chocolate or white chocolate." That’s a good choice considering dark chocolate is rich in flavonoids, which may protect against heart disease and stroke, according to a Tufts University review

Stick to seasonal produce

The Queen is all about eating strawberries in the summer, but McGrady says she won’t touch them in the winter. “She absolutely does eat seasonal," he told RecipesPlus.

While eating out-of-season strawberries might not seem like a big deal, there are real benefits to following Mother Nature’s lead when it comes to produce. Out-of-season food travels thousands of miles before it hits store shelves, which may compromise its nutritional value. Vitamin C is particularly unstable: Research from Bangladesh found that tomatoes lose more than half their vitamin C over the course of eight days.

If you can’t grow fruits and vegetables from your own garden like Queen Elizabeth does, we suggest hitting up your local farmer’s market. You don’t need a royal budget, either.

Eat more fish

The Queen often has smoked salmon sandwiches with her afternoon tea and a grilled fish for lunch or dinner. Do the same to keep your brain sharp: People performed better on a working memory test after taking a daily omega-3 supplement for six months, according to a PLOS One study, and salmon is one of the best sources of omega-3s.

Sip some tea

This wouldn’t be a story about the royals without a reference to tea, would it? The Queen’s favourite, Earl Grey, may lower cholesterol, thanks to the flavonoids in bergamot. Just smelling the oil was shown to reduce blood pressure in a European Journal of Preventive Cardiology study. And that’s not even mentioning the benefits of black tea in general: the tannic tea may lower your blood pressure, reduce your risk of ovarian cancer, and promote weight loss. No fine china necessary.
