10 foods that speed up your metabolism, according to nutritionists

A fast, efficient metabolism is one of the simplest ways to support healthy, sustainable weight loss. While genetics and activity levels play a role, the food you eat can significantly influence how quickly your body burns calories and fat. Here are 10 nutrient-packed foods that nutritionists recommend to naturally boost your metabolic rate.

Cruciferous vegetables

Broccoli, cabbage, cauliflower, and Brussels sprouts are rich in vitamins B and C, as well as calcium—three key nutrients for metabolic function. They also contain sulforaphane, a compound that supports detoxification, and are high in both water and fibre, making them excellent for fat burning.

Lentils

Packed with iron, lentils help transport oxygen throughout the body, improving energy levels and encouraging your metabolism to work harder. They’re also a great source of plant-based protein, making them a staple for vegetarians and meat-eaters alike.

Beans

Whether red, black, or kidney, beans are loaded with fibre that promotes satiety, regulates post-meal insulin levels, and improves insulin sensitivity over time. The result? Less fat storage and a more stable metabolism.

Lean white meats

Chicken and turkey are among the purest sources of protein, which fuels muscle maintenance—and the more muscle you have, the more calories you burn at rest. Muscles require more energy to sustain themselves, making protein a vital part of any metabolism-friendly diet.

Citrus fruits

Low in sugar and high in vitamin C, citrus fruits such as oranges, grapefruits, and lemons help your body metabolise fat more efficiently. Their antioxidant properties may also help reduce the glycaemic impact of other foods eaten during the same meal.

Oats

A favourite among athletes, oats help keep insulin levels stable and prevent blood sugar spikes that can trigger cravings. High in soluble fibre, they also promote a feeling of fullness and support steady energy release.

Chilli peppers

Thanks to capsaicin, the compound that gives chilli its heat, these fiery peppers can slightly raise body temperature, prompting your metabolism to burn more calories—whether you’re resting or active.

Cinnamon

Adding cinnamon to foods like coffee or fruit can help regulate blood sugar by moderating the body’s insulin response. Balanced glucose levels mean less fat storage and more efficient energy use.

Berries

Blueberries, raspberries, and strawberries are rich in antioxidants that help stabilise blood sugar and reduce body fat over time. They’re also low in calories and high in fibre, making them an ideal snack.

Garlic

Garlic not only supports healthy blood sugar levels, but research suggests it can increase the number of calories burned while reducing the body’s fat production. A simple addition to savoury dishes with a big metabolic payoff.

Your metabolism is essentially your body’s internal engine—turning food into energy, fuelling every cell, and deciding whether to burn or store fat. While you can’t control every factor, incorporating these metabolism-friendly foods into your daily meals can give your body a natural, long-lasting boost.
