Eating enough fruit and vegetables is vital for a healthy, balanced diet. Science has linked diets rich in fruit and vegetables to lower body mass, improved health outcomes, and weight loss.¹ ²
Unfortunately, not many people hit the recommended daily servings of fruit and vegetables. Researchers believe low intake causes about 31% of ischaemic heart disease and 11% of strokes worldwide.³
The World Health Organization recommends five servings of fruit or vegetables a day, but only one in ten adults meets that requirement in the US.⁴
Smoothies are an easy and tasty way to get your daily fruit and veg fix.
When making your smoothie, consider adding these ingredients for their weight-loss benefits:
1. Protein
This macronutrient helps with weight loss because it keeps you feeling fuller for longer (satiated), and protein requires more calories to digest than fat and carbohydrates.⁵
You may want to add one of the following protein sources to your smoothie:
Low-fat plain yogurt
Protein powder
Silken tofu
Soy milk
2. Fiber
Fiber increases satiety and alters gut hormone secretion. Large epidemiological studies have shown an inverse relationship between dietary fiber intake, body fat, and weight.⁶
Some types of fiber act as prebiotics, which are vital for your gut health. Prebiotics are a food source for the good bacteria in your gut, contributing to a healthy gut microbiome.
These make excellent fiber-rich additions to your smoothies:
Avocado
Spinach
Kale
Kiwi
Papaya
Mango
Guava
Blueberries
Raspberries
Strawberries
3. Chia seeds
These tiny black seeds are nutritional bombs high in fiber, antioxidants, and good omega-3 fatty acids. They lower cholesterol levels and stabilize blood sugar levels. Chia seeds are hydrophilic, meaning that they attract water, so adding them can help thicken your smoothie and leave you feeling fuller for longer.⁷
4. Berries
Berries have high antioxidant levels, so adding a handful of berries to your smoothie will add immune-boosting and cancer-fighting benefits.⁸ Berries can make your weight-loss smoothie delicious with very few additional calories.
Many commercial smoothies contain lots of sugar, so they’re not ideal for weight loss.
When making your own, be mindful of hidden sugars, such as the sugar in sweetened yogurts. Use fruit to sweeten your smoothie instead of adding sugar, sweetener, or honey to it.

This smoothie is full of fiber, very low in calories, and the ginger adds a great zing. Protein powder is an optional addition that can keep you feeling full. Whiz together the following ingredients for a healthy blast of green magic:

3. Raspberry chocolate smoothie

2 tbsp raw cocoa powder
10oz unsweetened soy milk

Smoothies are a simple and delicious way to get your daily serving of fruit and vegetables. To maximize your smoothie’s weight-loss properties, add protein, keep the fiber content high, and throw in some chia seeds and a handful of berries. Homemade smoothies let you control the ingredients that go into your smoothie, ensuring no hidden sugars sabotage your weight-loss efforts.
