Are Overnight Oats Healthy? Unlocking the Truth

When it comes to food trends, overnight oats have caught the eye of many health enthusiasts. This convenient and customizable breakfast has become a staple for health-conscious people as a quick, healthy, and easy on-the-go option. 

However, are overnight oats truly healthy?

In this article, we’re going to discuss the nutritional profile of overnight oats, their benefits, and tips to make them a truly healthy option.  

What Are Overnight Oats?

Overnight oats are a convenient breakfast that is made by soaking raw oats in any liquid, typically milk or a dairy-free alternative (such as coconut, soy, or almond milk) overnight in the fridge. By soaking them for 8-12 hours, the oats soften and absorb the liquid and as a result, they require no additional cooking. 

The benefits of overnight oats include their versatility and easy preparation. Once you’ve soaked the oats, you can customize them based on your goals, needs, and preferences. From fresh fruits and nuts to seeds, spices, and sweeteners, the possibilities are endless, which allows for multiple flavor combinations. 

Are Overnight Oats Healthy for Weight Loss? 

Yes, overnight oats can be healthy for weight loss. However, it all comes down to the ingredients you add. To lose weight, you need to be in a caloric deficit, meaning that you need to eat fewer calories than your body needs (3). 

This means that you should keep track of your overnight oats and the rest of the meals you make throughout the day.

  • Customization. The versatility of overnight oats offers endless customization to help you achieve your calorie and macro needs. As a result, it can be a great option to fit any meal plan that promotes weight loss. 
  • Perfect for meal prep. Another way overnight oats can promote weight loss is that it’s perfect to use for meal prepping. You can make several jars for the week, which will allow you to stay on track with your daily calories.

Overnight Oats Benefits

Heart Health

Oats are high in beta-glucans, a type of soluble fiber that provides oats with incredible heart health benefits. Research has shown that fiber acts as a broom in the body, removing cholesterol particles. Therefore, it can lead to reduced LDL (bad) cholesterol levels, which lowers the risk of heart disease (2).

Tips for Making Overnight Oats Healthy

As we’ve seen, overnight oats can be a healthy breakfast, but it depends on the ingredients you add. Here are some tips to help you create healthy and balanced overnight oats. 

  • Choose whole-grain oats. Instead of instant oats, opt for rolled oats or steel-cut oats as they are less processed and retain more fiber and nutrients. Whole-grain oats provide complex carbs for sustained energy and are rich in fiber.
  • Include a protein source. Include a protein source in your overnight oats to enhance satiety and support muscle repair and growth. Include options such as Greek yogurt, protein powder, chia seeds, hemp seeds, and nuts. 
  • Add healthy fats. Incorporate healthy fats into your overnight oats for added flavor and satiety. Nut butter, chia seeds, flax seeds, hemp seeds, and chopped nuts are great sources of healthy fats, omega-3 fatty acids, vitamins, and minerals. 
  • Sweeten naturally. Avoid adding excessive amounts of sugar to your overnight oats. Instead, opt for natural ways to sweeten your overnight oats, such as using dates, unsweetened applesauce, mashed bananas, a drizzle of honey, or maple syrup. If you’re looking for a sugar-free alternative, try stevia or monk fruit. 
  • Increase fiber add-ins. Boost the fiber content of your overnight oats by adding fiber-rich ingredients, such as shredded coconut, chia seeds, hemp seeds, or ground flaxseeds. 
  • Use natural spices. Add different foods to change the flavor of your overnight oats. Mix different herbs, spices, or other flavorings, such as cinnamon, vanilla extract, almond extract, cocoa powder, nutmeg, ginger, and pumpkin spice.

I've struggled to maintain programs…

I've struggled to maintain programs before, but somehow I've been able to stick with this. I enjoy the workouts and have made healthy changes to my diet with the challenges. Its nice for something to really have stuck and worked. I did the sugar free challenge and it's really changed how I relate to the signals my body is giving me about the food I'm eating.

Our Journey

This has been an awesome journey for my wife and I. Not only are we losing weight , but we are living a new life style. Our eating habits have been reformed by following the meal plan and our bodies have become stronger by simply doing the ten minute, sometimes twenty minute workouts. It really has been easy and convenient to transition into a healthier routine and has truly re energized our lives moving forward into the future.

It Works! This program is working for me!

lynne R.
This program is working for me! After a little over a month, I have lost 10 pounds. Slow, but steady. Guided exercises are done daily and there is an option to do other routines beside the one chosen for the day. It is very helpful having the recipes for all meals plus a snack. Would like if we could know the ingredients the day before. Makes preparing alot easier. I like the fact that alternative foods are suggested in case you can't eat(or don't like) the recipes listed. This is a very good program. Stick to it and YOU will see results. I have!
