Smoothie Diet – Healthy & Nutritious Flexible Diet Plan

green smoothie

A smoothie diet seems like the perfect meal replacement to shred a few pounds.

It can be time saving and if done correctly, smoothies can be nutritious and full of vitamins.

So why not?

We did all the research for you and learned what the smoothie diet is all about.

Including also what makes a good smoothie and how a smoothie diet can help you lose weight.

What is the Smoothie Diet?

A smoothie diet is a meal plan that replaces 2 meals a day with smoothies.

It was created and popularized by Drew Sgoutas, a health coach and nutritionist. Since then, there have been many variations of the smoothie diet that often fall short of its belly fat burning promise.

In fact, it’s very easy to fall into the trap of consuming smoothies with too many fruits. Surely they will taste good, but they won’t be all that nutritious.

Too many fruits void all the benefits of a low calorie, smoothie diet.

The legit smoothie diet should be made of fruits, vegetables, protein, and healthy fats, the smoothie diet was designed to aid weight loss. So it doesn’t only help with weight loss but also is healthy, low in calories and rich in phytonutrients.

So far so good!

You can start off on a 3 day smoothie diet, or opt for 1 week (7 day), 10, or 21 days.

You are allowed to have 2 smoothies, 1 solid meal and 1 snack per day.

“Flex Day” Smoothie Diet

On days where you expect to be physically more active, and planning on exercising hard switch to a “flex day” option.

How it works?

Instead of 2 smoothies to replace 2 main meals, trim down to one smoothie and two regular meals.

That’s a personal preference in case you feel your body can’t cope better with solids on super active days.

Do remember, in order to lose weight, make sure you do not consume more than 1,500 (women)  and 2,000 calories (men) per day.

If you enjoy healthy eating but are not sure what kind of solid meals to eat, check out Shepherds Diet Food Guide for natural ingredients and not processed foods.

Smoothie Diet Ingredients

Don’t fall into the fruit smoothies trap. Smoothies should be tasty and most importantly nutritious enough to keep you satiated.

As they are going to replace a meal, it is important not to get carried away and make it a fruit smoothie.

Negative calorie foods are generally a good safe option to add to your smoothie if you ever run out of an ingredient.

Nevertheless, here are 5 components to nutritious and yummy smoothies:

  1. Vegetables or fruits
  2. Liquids to thicken such as unsweetened yogurt, Greek yogurt, milk (skim milk) and milk alternatives (coconut milk or cream, almond milk, soy milk, flax milk, rice milk, hemp milk)
  3. Flavor boosters such as spices, ginger, herbs, spirulina, chia seeds (natural)
  4. Protein and healthy fat such as protein powder, peanut butter, almond butter. Avocados are high in omega-3 fatty acids but it can easily drive your calorie intake up. So use it sparingly and not more than half an avocado per smoothie. MCT oil or medium-chain triglyceride oil can be used as a protein supplement too. MCT oil is made of coconut oil, palm oil, and other dairy oil sources.
  5. Grains such as oats lends the smoothie more body and helps to keep you satiated longer. Not all recipes require grains and hence it is optional.

Check out these 5 highly recommended ingredients by dietitians that will help you make the most delicious smoothies ever.

1. Dark leafy greens

Spinach for smoothie diet

Kale, spinach, celery, and other leafy vegetables are staples for making smoothies.

Green vegetables are bursting with fiber, folate, and phytonutrients. This is to ensure that you’re not missing out on any essential nutrients.

2. Cruciferous vegetables

Broccoli, cauliflower, bok choy, brussels sprouts, arugula, and radish are rich in cancer-fighting compounds. Power-packed with antioxidants, these vegetables strengthen the immune system and help to fight the flu and cold.

3. Nuts, nut butter, and seeds

variety of nuts for weight loss

Nuts add a nice earthy flavor and some bite to your smoothie.

Chia seeds, cashew nuts, walnuts, and peanuts are bursting with healthy fats that will slow your digestion and keep you fuller longer. Ground flax seeds are another option rich in omega-3 fat and protein.

Since nuts are high in calories, add not more than half an ounce of seeds or nuts. And not more than 1 tablespoon of nut butter per serving.

4. Greek yogurt, milk and milk alternatives

yogurt smoothie diet healthy

Adding Greek yogurt in your smoothie will give you the needed protein boost.

Packed with probiotics, the friendly bacteria in yogurt helps to maintain your gut health, and fortify your immune system. If you are into gut health, check out our kombucha recipes for weight loss.

Try to opt for non-flavored, plain Greek yogurt as the flavored version has excess sugar that adds to the calorie count.

If you choose to add milk into your smoothie, opt for skim milk, or one percent cow’s milk.

If you are vegan or dairy intolerant, milk alternatives such as unflavored almond milk, soya milk, flax milk or rice milk are suitable liquid options.

5. Spirulina

Spirulina is a nutrient powerhouse algae found in freshwater and sea water.

Often sold in powder form, spirulina is an ideal dietary supplement that is high in protein and antioxidants.

It is perfect for vegans or individuals who can easily be protein deficient. By adding 1 to 2 tablespoons of spirulina into a smoothie, you can easily meet your daily protein requirement.

6. Fruits

Fruits are optional. They do add a delicious natural flavor and are nutritious.

However, fruits can be high in sugar, so to avoid making your smoothie a desert, add only 1 cup of fruit per smoothie. This is equivalent to a serving of fruits.

Moreover, it is easy to get carried away by adding in too many fruits when mixing several fruits. So try to stick to a maximum of 2 fruits per smoothie, totaling to 1 cup of fruits.

Smoothie Diet Pros and Cons

We have created this image bellow to help you figure out the pros and cons and if this diet plan is right for you:

two-women-uses-smartphones-904381

1. Calorie restriction for weight loss

Weight loss happens when your body expands more energy than consumed.

On a smoothie diet, your calorie count should not exceed 1,500 calories per day.

An average adult woman needs to eat 2000 calories per day to maintain her weight. An average adult man needs 2,500 calories to remain status-quo.

To lose one pound of weight per week, women need to reduce calorie intake to 1,500 per day, and men to 2,000 calories daily.

Based on these numbers, ladies would have recorded a shortfall of 500 calories per day on a smoothie diet. And this calorie deficit will force your body to burn other sources of fat, to convert to energy.

What’s great about the smoothie diet is that you will not be nutritionally deficient.

Selecting the right mix of greens, liquids and natural flavors (such as herbs, spices and other ingredients listed above) ensures that your body is not traumatized, unlike crash diets.

2. Reduces insulin production over three days

As the smoothie diet requires consuming less food, your body will produce less insulin. With reduced insulin, the body is tricked into burning more fat.

The best way to maintain insulin levels low and fat-burning high is to sip the smoothie throughout the day.

Avoid downing the smoothie in a few gulps as this insulin levels to spike.

3. Boost human growth hormones

With only one solid meal per day, the smoothie diet is a form of mild fasting.

Studies indicate that intermittent fasting accelerates the production of human growth hormones (HGH).

HGH is important as it helps to build, maintain and repair healthy tissue in the brain and other vital organs.

Most importantly, we need more HGH as we age because HGH levels decline over time.

4. Rich in fiber and phytonutrients

According to the Food and Drug Administration (FDA), adults should consume 25 grams of fiber per day.

While most of us fall short of that benchmark at 15 grams per day, adding one or two smoothies helps us meet the daily fiber requirement effortlessly.

To put things into perspective, one cup of broccoli contains 2.3 grams of fiber. To consume 25 grams of fiber per day you will need to eat 10 cups of broccoli.

While this can sound like a copious amount of broccoli, blending them into a smoothie makes consuming fiber so much more palatable!

In short, smoothies help you achieve your daily fiber goals and ensure that your diet remains rich in phytonutrients.

In addition, the high fiber content in a smoothie makes you feel fuller on fewer calories and less bloaded, meaning flat belly here we come!

5. Easy to prepare

Whether you are a fulltime mum, working mum or corporate warrior trying to juggle multiple tasks in a day, blitzing up a smoothie is pretty convenient and and time saving.

You can cut short your preparation time by bagging your fruits and vegetables in zip lock bags. Simply toss the contents into the blender, add in your liquids, and your smoothie is ready in a jiffy!

6. Less calorie counting and food tracking

Unlike the majority of diet plans in the market, the smoothie diet does not require a food diary, carbohydrate or calorie counting.

Smoothies are generally lower in calories than full solid meals. And as long as you abide by the recommended recipes, it is almost impossible not to stay within your goal calorie intake.

With recipes and meal plans provided everything in a smoothie diet have been planned out. Just remember to have your recipe list on hand when you do grocery shopping.

7. Clear complexion and healthy hair

Consuming too much processed food stresses our digestive system. Too much acidity and toxins in the body can make our skin looks dull and rough.

Smoothies can act as a detox because they help to flush out the toxin and reinstate the ideal acid-alkaline equilibrium in the body. You will benefit from having smoother hair and healthier looking skin.

Cons

measuring tape mouth

1. Restrictive

I think that’s the biggest one… You won’t be able to eat much solids and to get the results, you will need to follow the recipes.

That means, forget about what you have in your fridge and go shopping to try finding that odd ingredient.

You won’t be able to have a meal together with friends, or go to restaurants. Not for 3 days, so avoid meet ups, you don’t want to be the one at a restaurant not eating anything.

2. Not sustainable

Smoothie diets practiced over extended periods may cause protein and iron deficiencies.

Not eating enough high-iron food such as spinach, kale, and nuts can cause your body to be iron deficient. And this may lead to anemia in the long run.

Moreover, living on a predominantly liquid diet is not something any of us can do!

3. Lack of protein

One of the major pitfalls of smoothie diets in general is its low protein content. So if you try to go solo and make your own smoothie diet recipes, do make sure to add protein in it 🙂

Our recipes featured here are specially curated to ensure that you continue to meet the protein, fiber and nutrient requirements to function at your best.

Throughout the day, you will be eating at least 50 grams of protein as recommended by the FDA.

So the smoothie not only serves as a meal replacement. It ensures that you consume a wholesome meal packed with protein, essential fat, fiber, and some carbohydrates.

Smoothie Diet Results

fitness and measuring tape

Walking the talk is important to truly understand what it feels like on a smoothie diet.

Smoothie diet before and after – I tried the 10-day green smoothie challenge and here’s how I felt during the 10 days:

Day 1: Felt weird to have two liquid meals per day. Surprisingly, the smoothies were pretty filling and were sufficient to last me to the next meal.

Day 2: Cravings are starting to kick in. The bread has never look so enticing and I had to make a mental note not to step into delis or cafes. Snacking on a handful of nuts helps to curb the hunger pangs.

Day 3: Perhaps this is the most challenging day for me. I tired easily at the gym and struggled through my workout which I would normally ace.  I slumped into bed early at 9 pm.

Day 4: I’m starting to think that I can cut down on meat post-smoothie-diet challenge. I feel lighter, more alert and my weight started to drop.

Day 5: I’m looking forward to prepping my smoothies in advance. I feel excited to try new recipes. My complexion looks clearer with no acne in sight.

Day 6: It’s the weekend! Instead of having a solid meal at the end of the day, I had grilled chicken breast for lunch. Making this swap helps it easier to stay connected with family and friends.

Day 7-9: I’m coping well but can’t deny the hunger. Boosting my snack intake when I feel lethargic has helped. My pants feel loose now.

Day 10: Finally, today marks the last day of a predominantly liquid-infused diet! I’ve lost 3 pounds over 10 days, I feel lighter and now have a flat stomach! Bowel movements have never been this easy. My belly bloat has reduced and this definitely perks me up emotionally!

Was the smoothie diet worth it?

Will I try the smoothie diet again? Only if I feel I need to.

It is a diet that I will adopt whenever I’ve overeaten, and dial back when I’ve lost the excess weight.

One tip, if you are planning on exercising, I (personally) would opt for light exercise options, such as walking, yoga and pilates. If you have a weight loss belt, that is the time to use it!

Tips To Make a Delicious and Healthy Smoothie

Blender

Do you know what kind of blender to use to make smoothies?

Are fresh fruits better than frozen ingredients?

Here are some questions smoothie newbies often ask, and I’ve pulverized the details for you to bite sizes.

What kind of blender to make smoothies?

You can either use a conventional blender or a smoothie maker.

The difference between a smoothie maker and a blender is that smoothie makers are portable and designed with convenience in mind.

Smoothie makers make one portion at a time. The jug conveniently transforms into a cup. This leaves you with less cleaning up to do. Since smoothie makers are smaller, it takes up less space.

But if you are making smoothies for 2 or more, then it makes sense to opt for a blender.

Whichever option you go with, you will still get a decent smoothie.

Fresh or frozen ingredients?

It’s a myth that fresh vegetables are better than their frozen siblings.

According to Sydney based dietician Lyndi Cohen, frozen vegetables may even have more nutrients than fresh produce.

This is because vegetables start to lose their nutrients once it is harvested.

By freezing the vegetables, the greens stop breaking down. And once it is defrosted, the vegetables are as fresh as when it was before freezing.

Blending on the go or prepping in zip bags?

Organizing your smoothies in advance will not only give your body a nutritious head start. You can whip up a smoothie in a matter of minutes!

Pack your mix of frozen fruits a week in advance into zip lock bags.

Add in frozen bananas, mangoes, pineapples along with your favourite vegetables.

For liquids, freeze Greek yogurt, milk and milk alternatives in ice cubes. Simply use 2 cubes to make a cup of healthy smoothie each time.

Warnings

Smoothie diets done wrongly can be detrimental.

Too many fruits and artificial sugar and your smoothie is loaded with calories.

Worst still, an inadequate smoothie will make you feel lethargic and ravenous.
