Why Do Smoothies Work for Weight Loss?

Simply put, weight loss occurs when our body is burning more calories than we are consuming. But skipping meals slows our metabolism causing more weight gain. I like to imagine our metabolism burns like a fire, and the food we eat is the lumber that keeps it burning.

Some foods, like processed foods, burn up quickly and create more smoke in the sense that they cause spikes of insulin and do not supply the body with long-lasting energy. Foods rich in nutrients like fiber, protein, healthy fats, vitamins, and minerals serve as the best energy source to support a bonfire metabolism.

“Smoothies are quick and easy to make and a much better option than skipping breakfast altogether!”.

Smoothies work for weight loss because they supply the body with essential nutrients to keep our metabolism burning all day long. Finding the best combination of ingredients can make a difference between weight loss and weight gain.

Alyssa Pacheco, RDN who specializes in PCOS (polycystic ovary syndrome) shared,

“One mistake I see people making is forgetting about healthy fats or protein when it comes to making their smoothie. Including just fruit in your smoothie is going to leave you feeling hungry quickly afterward.”

Four Steps Create the Best Weight Loss Smoothie

Here are four simple steps to help create the best weight loss smoothie with scientifically proven ingredients:

Prioritize Protein :

During weight loss, it’s common to lose a combination of lean muscle mass along with fat mass. To prevent the loss of lean muscle, increasing intake of protein is the best approach. Protein takes longer to digest and keeps you feeling fuller for longer which will help you stay in a calorie deficit[1].

Most people need 20-30 grams of protein to prevent loss of lean muscle, this is easily obtained by including 1-2 scoops of protein powders, ½ cup firm tofu, or ¾ cup Greek yogurt. More active adults may need more protein, but consuming too much protein may stall weight loss as excess protein is stored as body fat.

Dr. Guntipalli, MD and Medical Director and Owner of Sanjiva Medical Spa provides this breakdown for his patient’s smoothies, “aim for a blend of 30% protein, which is thermogenic and helps keep you full. Use sources like plant-based protein powders or Greek yogurt.”

Add Fruits and Vegetables:

The best weight loss smoothies contain antioxidant-rich foods like berries and dark leafy greens. Dr. Guntipalli, MD shared, “40-50% should be vegetables, such as leafy greens, for essential nutrients. Fruits, providing natural sweetness and fiber, should make up 20-30% of the mix”. These foods are rich in vitamins and minerals to help support a healthy body and increase energy production. Try using fruits to sweeten your smoothie instead of using other sweeteners like agave and honey.

Focus on Fiber:

Fruits like raspberries and blueberries are tasty, rich in antioxidants, and very high in fiber, 1 cup contains about 8 grams! Fiber is fuel for our gut bacteria which also helps to support a healthy weight.

Michelle Saari MSc, RD, EHealth project agrees,

“Most people today lack enough fiber in their diet, the current average in the United States is just 15 grams. This is well below the 28-35 grams that is recommended. Fiber can help people lose weight and fruits and vegetables are a rich source of it.”

Measure Portions of Healthy Fats:

Create a complete meal by including healthy fats. Omega-3-rich foods like chia seeds, flaxseed, hempseed, walnuts, and almonds support healthy nervous system function and weight control.

Alyssa Pacheco, RDN shares, “Chia seeds are one way to add heart-healthy fats to your smoothie, but they can also add a whole lot of fiber too! Two tablespoons of chia seeds will add a whopping 10 grams of fiber to your smoothie to keep you feeling full for hours.”

What to Avoid?

When creating smoothies, the biggest mistakes I see are adding foods that are too high in sugar and unhealthy fats. Fruit is healthy but adding five fruits to a smoothie is excessive and will cause spikes in insulin resulting in weight gain. Similarly, adding “ natural sugars” like date syrup, agave, and honey should be limited because they contain added calories[2].

Alex Evink, MS, RD agrees, “Stick to fresh, minimally processed foods and read food labels when adding yogurt, some yogurts contain more sugar than others” which can slow down weight loss.

Also be mindful of portions of ingredients, especially calorie-dense foods[3] like nut butter and avocado. Although these fats can be healthy, Saari MSc, RD, EHealth project recommends,

“Measure out your ingredients, especially if it’s nut butter, nuts, protein powders, and liquids. Where many people go wrong is they add too many ingredients, and the result is a very high-calorie drink.”

Destini Moody, RDN, LDN, founder of The Athlete’s Dietitian and an expert panel at Garage Gym Reviews, shared

“Banana, chocolate, and peanut butter smoothies are tasty, but just two tablespoons of peanut butter have 200 calories, and going overboard can quickly become counterproductive.”

How to Maintain Long-Term Weight Loss:

For successful long-term weight loss, I like to refer to the National Weight Control Registry, which shares stories and studies of people who have lost over 30 lbs and have kept it off for over one year[4].

78% of participants reported they eat breakfast every day. Eating a healthy breakfast provides nutrients to support healthy brain and muscle function, resulting in better food choices and a more active lifestyle. But not all of us can eat a full meal in the morning.

Chelsea Oarr, RD, CDN who works with NYU Langone’s Weight Loss Program in NYC shared,

“ Many patients will often state they just do not have an appetite in the morning before they leave for work, while others state they don’t have time to stand over the stove and make oatmeal or eggs.” Making a smoothie for breakfast is a quick solution to a busy lifestyle and allows one to maintain long-term weight loss.
