Smoothies are a great way to consume nutrient-dense fruits and vegetables, instead of unhealthy snacks/meals with empty calories!

All of these flat tummy smoothie recipes contain whole plant-based ingredients to help you lose weight. Here are some examples of wholesome, fat-busting ingredients to add to your smoothies:

yogurt with blueberries, nuts, and oats.
  • Berries – Berries have a high water content and plenty of fiber and important vitamins!
  • Avocadoes – Avocadoes are low in carbs and high in heart-healthy fats and fiber. This makes them super filling, which means less snacking!
  • Nuts or nut butter – Nuts are loaded with antioxidants and high-quality protein! Antioxidants protect your cells from damage caused by oxidation.
  • Oats – A well rounded ingredient with complex carbs, fiber, high-quality protein, and essential amino acids. As an added bonus, oats taste delicious in weight loss smoothies!
  • Carrots – Carrots taste great with tropical flavors! They’re nutrient powerhouses that promote good vision, balance your blood sugar, and help with weight loss.
  • Yogurt – Greek yogurt is a great way to add filling protein! Use unsweetened Greek yogurt to avoid added sugars.
  • Flax and chia seeds – Both are packed with nutrients, including protein, fiber, and omega-3’s. A little goes a long way!
  • Bananas – Bananas naturally sweeten a smoothie without the need for added sugar! They’re a good source of soluble fiber and potassium too.
  • Grapes – A good source of powerful antioxidants and important vitamins and minerals like copper and vitamin K.
  • Greens – Spinach and kale are good options! Spinach has a mild flavor and delicate leaves that blend up nicely.

How to Lose Belly Fat

While a weight loss smoothie can help you lose belly fat, it’s no cure-all. It must be a part of a healthy diet and regular exercise.

According to health.com there are specific things you can do to lose belly fat and fat overall.

Avoid Added Sugar

There are two types of sugar – added and natural sugar. Natural sugar is sugar that occurs naturally in the food you’re eating. Added sugar is sugar that’s added to foods during preparation.

Here are a few examples of added sugar:

  • White sugar
  • Turbinado sugar
  • Brown sugar
  • Honey
  • Maple syrup
  • Agave

Look for smoothies that use only fruit to sweeten them. Avoid smoothies with turbinado sugar, honey, fruit juice from concentrate, or other added sugars. They just increase the calorie count with little to no nutritional benefit.

Eat More Protein

Research shows this macronutrient can reduce cravings, boost your metabolism, and help you eat less calories during the day!

There is a study that suggests protein may be linked to lower levels of abdominal fat. You can increase the amount of high-quality protein you consume by eating eggs, fish, legumes, meat, nuts, and dairy products.

a spoonful of nut butter,

Look for smoothies with Greek yogurt, nut butter, cashews, cottage cheese, or high-quality protein powder without additives.

Eat More Fiber

Look for smoothies with plenty of soluble fiber! The best way to get fiber is to eat more plant-based foods, specifically vegetables and fruit.

Soluble fiber slows the migration of food through your digestive system, helping you feel full for a longer period of time.

These foods are high in soluble fiber:

  • Oats
  • Apples
  • Avocadoes
  • Pears
  • Sweet potatoes
  • Carrots
  • Flax seeds
  • Raspberries

Exercise Regularly

Flat belly smoothies are a great way to up your nutrients, but exercise is an important part of losing weight!

Try to fit aerobic exercise into your daily routine! Aerobic exercise like running, brisk walking, swimming, or jump roping can permit major reductions in visceral fat. Visceral fat is the fat in your stomach that wraps around your internal organs.

The best way to make the most of weight loss smoothies is to enjoy them in conjunction with a healthy exercise routine and well-balanced diet.

Tips for Weight Loss Smoothies:

  • Avoid added sugar like turbinado, sugar, maple syrup, fruit juice concentrate, canned fruit in syrup, or honey.
  • Instead, use fruit to naturally sweeten your smoothies. Bananas, mango, pineapple, apples, and berries are great options.
  • Add leafy greens whenever possible! Spinach is the best option if you don’t want to taste it too much. Greens add tons of nutrients and antioxidants to a smoothie.
  • Add protein to smoothies to keep you full for longer. Nut butter, chia seeds, Greek yogurt, cottage cheese, oats, flax seeds, and protein powder are all good options.
  • Include fiber for a healthy gut and good digestion. Raspberries, avocado, oats, apples, almonds, and pears are all rich in fiber.
  • Avoid sugary liquid bases and opt for plant-based milk instead. Unsweetened almond milk is my favorite liquid base. Whenever I add juice, I always use juice that’s not from concentrate and I add it in small quantities.

It’s my favorite fat belly detox smoothie, which is why it’s number one on this list.

2. High Fiber Smoothie

This beet smoothie features tart raspberries, earthy beets, juicy pomegranate arils, and sweet apple! If you don’t have a high-speed blender, go for cooked beets instead of raw ones.

6. Banana Avocado Smoothie

Avocadoes are rich in monounsaturated fat, specifically oleic acid, which has been linked to decreased inflammation and a lower risk of heart disease!

Since avocadoes are full of fat and fiber, they keep you feeling full longer which is good for weight management.

This banana avocado smoothie is a delicious way to add avocadoes to your smoothies. It has nutrient-dense spinach, almond butter, banana, and avocado in it, plus it tastes delicious!

7. Chunky Monkey Smoothie

This tropical smoothie has a sunny orange hue and it’s packed with beta-carotene from the carrots. Carrots are high in fiber and low in calories, which makes them great for smoothies!

If you have a high-speed blender, you can chop them and add them raw. If you don’t, it’s best to steam them first to achieve a smooth texture.

What are the healthiest things to add to smoothies?

The healthiest ingredients to add to smoothies are plant-based whole foods with no additives or refined sugar. It’s best to use a combination of ingredients that provide high-quality protein, fiber, and complex carbohydrates. Berries, leafy greens, nuts, oats, cucumber, avocado, chia seeds, pineapple, and nut butter all great options!

Which fruits burn belly fat?

There is no cure-all fruit that gives you a flat stomach right away. There are fruits that are packed with antioxidants, fiber, and nutrients that help promote weight loss though. Raspberries are high in flavonoids and fiber, plus low in calories! Apples, berries, oranges, and avocadoes are great options too!

Can you lose weight by just drinking smoothies?

While smoothies can help you lose weight, it really depends on a variety of factors. Weight loss is a long term habit that includes regular exercise, healthy eating, and a decrease in calorie consumption. Smoothies are a great way to consume antioxidants, fiber, and protein all in one drink.

What smoothies should I avoid when trying to lose weight?

Avoid smoothies that contain lots of added or refined sugar and unhealthy fats. Takeout smoothies often have added sugar, ice cream, fruit juice concentrate, or other added sugars in them. It’s best to make smoothies at home so you can control what goes in them. Fill them with healthy fats (like nuts and avocadoes), leafy greens, frozen fruit, and other whole foods.
