Low calorie fruits

Low calorie fruits: Apple

1. Apples

Calories: 32 per apple | Five-a-day count: One apple = one

An apple a day keeps the doctor away, and the weight off. Nutrient-rich apples contain a flavonoid called quercetin, which is thought to lower the risk of chronic disease. And one small apple is just around 32 calories.

“One medium-sized apple counts as one of your five a day, so this is a really easy option to just grab when you’re on the go. Apples are high in fiber, vitamin C, and numerous antioxidants,” says Mina, founder of nutraceutical company Formulate Health. Just remember that there tends to be more vitamin in raw vs cooked food because of the way the nutrient reacts to heat and processing methods.

“As well as being a tasty snack, apples can also be used in breakfasts either mixed in with some homemade granola or enjoyed as a porridge topping. If you’re looking to lose weight, stewed apples can be a great option for desserts, too, providing you with the sweetness of an apple crumble or pie, without the high-fat contents,” Mina adds.

Not only are blackberries good for you, but they're also low in calories. Full of fiber, blackberries are also one of the best sources of antioxidants, which may reduce the risk of many diseases. And they contain a single calorie per berry.

“A serving of nine blackberries has more than 30mg of vitamin C which is half the daily recommended amount. Vitamin C is really important for collagen formation in bones, connective tissue, and blood vessels, helping to strengthen joints, heal wounds and regenerate the skin,” says Mina.

“Vitamin C has also been shown to help the body absorb iron, reduce the length of common cold and even reduce free radicals in the body. Plus, they’re delicious. Especially in a smoothie or blended to make a blackberry coulis for drizzling over melon.”

Known for being low in calories but exceptionally high in nutrients, one heaped tablespoon of blueberries contains just eight calories, so you can have three tablespoons and not even hit 30 calories.

“Blueberries are low in calories and fat and provide a really substantial amount of healthy fiber. They’re also an excellent source of vitamin K1 which has been found to help reduce blood clotting, promote bone health and balance out calcium levels in the blood,” says nutritional expert Mina Khan.

“Blueberries are also packed with potassium, which is great for helping to reduce blood pressure and water retention, alongside vitamin C, which is crucial for skin health and immune function. These small but powerful berries also contain magnesium, which is great for those suffering from sleep problems and stress. There’s a reason why so many people refer to blueberries as a superfood.”

Mina comments; “Fresh cherries contain generous amounts of fiber, which we know is great for promoting a healthy digestive system, reducing cholesterol, and balancing blood sugar levels. Cherries also contain C, A, and K vitamins which help aid an array of functions in the body. They also contain antioxidants such as beta-carotene, and the essential nutrient choline, which play key roles in cell growth, neuron communication and the maintenance of vital organs such as the heart, lungs, and kidneys.”

What’s more, they look so pretty and are fantastic for adding to a smoothie bowl or fruit salad.”

It's thought to curb appetite but can react with certain drugs such as statins, so if you're taking medication check before eating.

“Grapefruits are rich in fiber, which helps maintain a healthy digestive system and promotes greater feelings of fullness, which is excellent for weight loss, especially considering its low calorie total. Grapefruits also contain substantial amounts of vitamin C, vitamin A, magnesium, thiamine, and folate, which work together to improve general feelings of wellness in the body and mind,” says nutritionist Mina Khan.

They’re also high in fiber and low in calories, making them an excellent snack choice to keep you going during the day. The antioxidants found in kiwis also help contribute to a healthy, strong immune system. So eating kiwi regularly could help prevent the onset of viruses, colds, and other common illnesses.”

8. Oranges

Calories: 62 per orange | Five-a-day count: One orange = one

A thirst-quenching, medium-sized orange contains around 62 calories and is a good source of fiber, calcium, and vitamins A and C.

Mina adds; “I’d recommend eating them whole as opposed to pressing them to make a juice or smoothie. This is because when they’re blended, they’re really easy to overeat, as a single glass of freshly squeezed orange juice can contain four or five oranges, which of course means you’re consuming four or five times as much calories and sugar, without benefitting from the feelings of fullness you’d get from eating the fruit whole.”

Nutritionist Mina shares; “Peaches contain a broad range of vitamins, including vitamin C, A, E, and K as well as potassium, copper, and manganese. These vitamins provide many health benefits including skin health, digestion, blood pressure, and more. One of my favourite peach recipes is a feta and peach salad. Simply throw together some lettuce leaves, spinach, or rocket with some crumbled feta cheese and top with sliced peaches. Although it sounds simple - trust me - it’s one of the yummiest salads you’ll try.”

“Copper boosts immunity, cholesterol metabolism, and nerve function, while potassium improves muscle contractions and heart function. Honey poached pears are great when paired with a nice thick natural yogurt, and a great go-to dessert when trying to keep an eye on your weight.” Mina adds.

For this reason, plums can be a great choice for those suffering from constipation or other digestive issues. Healthy plum crumbles are also really easy to make and provide a hearty dessert option.

Vitamin K has been found to lower the chance of blood clotting and promote healthier bone growth, whilst vitamin C is known for its benefits in skin health and immunity,” states Mina.

“If you enjoy grapes but are looking for another way to eat them, try freezing them and covering them in sugar-free jelly crystals. They’re a great option for a low calorie treat, especially for those with a sweet tooth.”

“One slice of watermelon contains a decent amount of vitamin A and C. As its name suggests, watermelon consists mostly of water (91%). This low calorie fruit is an excellent way to stay hydrated, especially for those who struggle to get their water intake each day.
