5 Smoothies for Weight Loss

Berry and Greek yogurt, apple and oat, and banana and peanut butter smoothies are practical options for weight loss when their portions fit your overall eating pattern.

No smoothie causes weight loss on its own. These recipes combine fruit with ingredients that provide protein or fiber, which can help with fullness. For a broader look at choices beyond smoothies, see the best drinks for weight loss.

What are the 5 best smoothies for weight loss?

The five smoothies below are useful starting points, not a proven ranking: we found no clinical studies comparing these recipes for weight loss. Each makes one serving, and ingredient weights are approximate. Use a smoothie as a snack or as part of a meal, depending on your appetite and needs.

1. Berry and Greek yogurt smoothie

Greek yogurt supplies protein, while berries and chia seeds add fiber. Together, they make a more substantial blend than fruit and water alone. Choose plain yogurt so you can control how much sweetness you add.

Ingredients

• 1 cup mixed berries, fresh or frozen (about 140 g)
• 3/4 cup plain Greek yogurt (about 170 g)
• 1 cup loosely packed spinach (about 30 g)
• 1 tablespoon chia seeds (about 12 g)
• 1/2 cup water (about 120 mL)

Steps

1. Add the berries, yogurt, spinach, chia seeds and water to a blender.
2. Blend until smooth, adding a little more water if needed.
3. Serve immediately.

Use it as a snack or alongside other foods at a meal. If you do not like spinach in smoothies, leave it out; the berries and chia still contribute fiber.

Evidence: Protein and fiber can help with fullness, but there is no clinical evidence here that this particular smoothie causes weight loss. Your overall intake and how satisfying you find it matter more than the combination itself.

2. Apple and oat smoothie

Apple and rolled oats contribute fiber, while Greek yogurt adds protein and a creamy texture. Keeping the apple peel adds fiber, provided you wash the fruit first. Cinnamon adds flavor without requiring a sweetened yogurt.

Ingredients

• 1 cup chopped apple, with peel (about 125 g)
• 1/4 cup dry rolled oats (about 20 g)
• 3/4 cup plain Greek yogurt (about 170 g)
• 1/2 cup water (about 120 mL)
• 1/4 teaspoon ground cinnamon (about 0.6 g)

Steps

1. Wash, core and chop the apple.
2. Add the apple, oats, yogurt, water and cinnamon to a blender.
3. Blend until smooth and serve.

This can work as part of breakfast or as a snack. If the oats make it thicker than you like, blend in more water; the serving does not need added juice or sweetener to be useful.

Evidence: The ingredients provide protein and fiber, but this exact recipe has not been established as a weight-loss treatment. Fullness varies from person to person, and a smoothie may not be as satisfying to you as eating the ingredients separately.

3. Banana and peanut butter smoothie

Banana provides sweetness and some fiber, while Greek yogurt and peanut butter contribute protein. Peanut butter also adds richness, but its energy adds up, so measure the amount rather than pouring it directly into the blender.

Ingredients

• 1/2 cup sliced banana (about 75 g)
• 3/4 cup plain Greek yogurt (about 170 g)
• 1 tablespoon peanut butter (about 16 g)
• 1/2 cup unsweetened soy milk (about 120 mL)

Steps

1. Add the banana, yogurt, peanut butter and soy milk to a blender.
2. Blend until creamy, adding water if you prefer a thinner drink.
3. Pour into a glass and serve.

Try it when you want a more filling-tasting snack or include it with breakfast. Look for peanut butter with an ingredient list that suits your preferences; you do not need a sweetened version for the recipe to work.

Evidence: Protein can help support fullness, but there is no established weight-loss effect for this smoothie. Peanut butter is not a fat-burning ingredient, and adding extra amounts can change how the drink fits into your day.

4. Pear and spinach kefir smoothie

Pear supplies fiber, and plain kefir provides protein. Blending the whole pear rather than using pear juice keeps the fruit’s pulp in the drink. Spinach adds a mild vegetable flavor without needing a separate vegetable juice.

Ingredients

• 1/2 cup chopped pear, with peel (about 80 g)
• 1 cup loosely packed spinach (about 30 g)
• 3/4 cup plain, unsweetened kefir (about 180 mL)
• 1/2 cup water (about 120 mL)

Steps

1. Wash and core the pear, and wash the spinach.
2. Add the pear, spinach, kefir and water to a blender.
3. Blend until smooth and serve.

Use this as a snack or add it to a meal that needs more fruit or vegetables. Choose unsweetened kefir if you want to avoid added sugar, and check its label if protein content matters to you.

Evidence: Pear and kefir can contribute useful nutrients, but this recipe has not been shown to produce weight loss. Kefir is not necessary for weight loss; use it if you enjoy it and tolerate it.

5. Mango and silken tofu smoothie

Silken tofu provides plant protein and gives this smoothie a creamy texture. Mango supplies sweetness, and spinach adds another source of fiber. It is a dairy-free option when made with tofu that contains no dairy ingredients.

Ingredients

• 1/2 cup mango pieces, fresh or frozen (about 80 g)
• 1/2 cup silken tofu (about 120 g)
• 1 cup loosely packed spinach (about 30 g)
• 1/2 cup water (about 120 mL)
• 1 teaspoon lime juice (about 5 mL)

Steps

1. Wash the spinach and prepare the mango if using fresh fruit.
2. Add the mango, tofu, spinach, water and lime juice to a blender.
3. Blend until smooth and serve.

Have it as a snack or alongside a meal. If you want a thinner consistency, add water rather than juice; the mango already supplies fruit flavor. Check the tofu label if you need to avoid particular allergens.

Evidence: Tofu can contribute protein, but clinical research has not shown that this smoothie leads to weight loss. Its usefulness depends on whether you enjoy it and how it fits into your overall diet.

How can you use smoothies for weight loss?

Weight loss generally requires an overall calorie deficit over time, rather than one special food or drink. A calorie calculator can help estimate a starting intake, but its result is an estimate, not a prescription. Individual needs vary with factors such as body size, activity, health and life stage.

Make room for the smoothie. Decide whether it is a snack or part of a meal instead of automatically adding it on top of your usual intake. If a smoothie leaves you hungry, pair it with other food or adjust the ingredients; it does not need to replace a complete meal.

Keep the fiber. Blend whole fruit and vegetables rather than relying on juice, and leave the pulp in the drink. Wash produce before using it. Frozen fruit is convenient too; choose unsweetened fruit when you want to control added sugar.

Include a protein source. Plain Greek yogurt, kefir, silken tofu and unsweetened soy milk are options. Plant-based milks differ in protein, so check the label rather than assuming they all provide the same amount.

Watch the extras without banning them. Nut butters, seeds and oats can add flavor and nutrients, but large amounts also add energy. Measure them when you want a consistent serving, and taste the smoothie before adding honey, syrup or sweetened toppings.

Choose what satisfies you. A smoothie is convenient, but it is not inherently better for weight loss than a meal made from the same ingredients. If you prefer chewing your food or find that drinks leave you hungry, a yogurt bowl or another balanced meal may suit you better. Sustainable eating, activity and sleep habits matter more than a single recipe.

Handle leftovers safely. Serve smoothies promptly or refrigerate them. Discard a smoothie left at room temperature for more than 2 hours, and clean the blender and produce before preparing another batch.

Who should be careful, and when should you see a doctor?

If you have diabetes, smoothies containing fruit can affect blood glucose; consider your usual carbohydrate plan and speak with your clinician or dietitian about portions, especially if you use insulin or other glucose-lowering medication. If you take warfarin, keep your intake of vitamin K-rich greens such as spinach consistent and ask your clinician about dietary changes.

People with kidney disease may need individualized advice about protein or potassium. Avoid ingredients you are allergic to, such as peanuts, dairy or soy. During pregnancy, and for children and teens, seek professional advice before following a restrictive weight-loss plan.

If you have a history of an eating disorder, get support from a qualified clinician or dietitian before pursuing weight loss. See a doctor for unexplained weight loss or persistent symptoms such as unusual fatigue or excessive thirst.
