Diet myths and What Science Really Says

Published by


Eating right can feel like solving a puzzle with so many pieces, especially with all the confusing diet myths and advice we hear. Carbs, fats, and proteins—what’s good, what’s bad, and what’s downright myth? You’ve probably heard someone say, “Carbs will make you gain weight,” or “Fats are bad for your heart.” But what does science really say about these essential nutrients?

In this article, we’re going to pull back the curtain on some of the most common diet myths related to carbs, fats, and proteins. We’ll explore what scientific research tells us and break it all down into simple, easy-to-understand facts. No more confusion or fear; just clear information to help you make the best food choices for you and your family. Let’s dive into the truth and discover what our bodies really need to be happy and healthy!

Myth 1: All Carbs Are Bad for You

Truth: Carbohydrates are like fuel for our bodies, and they come in two main types: simple and complex.

Simple carbohydrates, also known as sugars, are found in things like candy, soda, and pastries. They give you a quick burst of energy but don’t last very long. Imagine lighting a piece of paper on fire; it burns bright but goes out quickly. Eating too many simple carbs can lead to weight gain because the energy they provide is often more than what the body needs at that moment, and the extra gets stored as fat.

Despite some diet myths, complex carbohydrates, on the other hand, are found in whole grains like brown rice and whole wheat bread, vegetables, and fruits. These are like logs on a fire; they burn slower and give you steady energy over a longer period. This is because complex carbs contain fibers and starches that take longer to break down in the body. They not only provide energy but also help with digestion and make you feel full and satisfied after eating.

So, while it might be tempting to reach for a sugary snack for quick energy, choosing a complex carbohydrate like an apple or a piece of whole-grain bread is usually a better choice. It will give your body the energy it needs without the sudden crash that comes with simple sugars. And because complex carbs are often found in foods that have other important nutrients, like vitamins and minerals, they contribute to an overall healthier diet.

In short, not all carbs are bad. It’s about choosing the right kinds of carbohydrates and understanding how they affect our bodies. By favoring complex carbs and being mindful of simple sugars, we can enjoy the energy and nourishment carbs provide without the negative side effects.

Myth 2: Low-Carb Diets Are Always Best for Weight Loss

Truth: Low-carb diets have become quite popular in recent times. People think that cutting out carbs, or the foods that give us energy, will help them lose weight. But the truth is, it’s not the same for everyone. Just like we all look different and enjoy different hobbies, our bodies might need different foods to feel their best.

For some people, eating fewer carbs might work well, but it’s not a magic solution that fits everyone. Eating a balanced diet that includes a healthy amount of carbohydrates might be just as good for losing weight. Carbohydrates are found in foods like bread, rice, fruits, and vegetables, and they help give our bodies the energy we need to do everything from running and playing to thinking and creating.

What’s most important is listening to your own body and what it needs. A doctor or a nutritionist can help you understand what foods are best for you. They can guide you to find a diet that includes the right balance of carbohydrates, along with other important nutrients, to help you reach your weight goals and feel great. It’s not about following a trend; it’s about finding what truly works for you and makes your body happy and healthy.

Myth 3: All Fats Are Unhealthy

Truth: Fats are an important part of what we eat, even though some people think they’re always bad. They give us energy and help our bodies use vitamins properly. But not all fats are the same. There are bad fats like saturated and trans fats, which can be harmful to our hearts. Then there are good fats, called unsaturated fats, found in things like nuts, avocados, and fish. These good fats can actually help keep our hearts healthy. So, while it’s good to be careful about eating too many fats, especially the bad ones, we shouldn’t cut out all fats from our diet. The trick is to eat more of the good fats and less of the bad ones, so our bodies can work the way they should.

Myth 4: Eating Fat Makes You Fat

Truth: Diet myths often claim that eating fats means you’ll gain weight. However, the real problem is eating too much of anything, not just fats. If you consume more calories than your body needs, weight gain might occur. But fats are not all bad. In fact, some fats are good for you and important for your health. Think of them as a part of a balanced meal, like a sprinkle of olive oil on a salad or a slice of avocado on toast. These healthy fats help your body work properly and can even make your food taste better. So, don’t be afraid of fats. Just like anything else, the key is to enjoy them in moderation, as a part of a healthy diet. That way, you can debunk diet myths and enjoy the foods you love without worrying about gaining weight


Diet myths of Proteins
Myth 5: More Protein Means More Muscle

Truth: Protein is like the building material for our muscles. Think of it as the bricks that help build a strong house. But just like building a house, there’s only so much you need. If you have too many bricks, they just pile up without doing any good. In the same way, eating too much protein won’t make your muscles bigger or stronger. Your body uses what it needs and might turn the extra into fat. So, more protein isn’t always better. It’s about finding the right amount for you. This can depend on things like how big you are, how old you are, and how active you are. Just like with anything else you eat, balance is key. You don’t need to avoid protein, but you also don’t need to eat it all the time. Finding the right amount helps your body be its best.

Myth 6: Plant-Based Proteins Are Incomplete

Truth: Many people think that only meat has all the things your body needs to build strong muscles, but that’s not true. Even if you don’t eat meat, you can still get everything your body needs from plants. Some plants don’t have everything by themselves, but if you eat different ones together, they can give you all you need. For example, beans might have some of the things your muscles need, and rice might have the rest. If you eat them both in a meal, you get everything your body needs to be strong. People who only eat plants, like vegetarians and vegans, can still have healthy muscles by eating different plant foods together. So, you don’t need to eat meat to be strong. Just plan your meals with different plants, and you’ll get all the good stuff your body needs.

Digging Deeper: A Closer Look at Each Nutrient


Carbohydrates are like the fuel for our body’s engine. Imagine your body as a car that needs gas to run. Carbohydrates are that gas, giving us the energy we need to go about our day. When we eat foods rich in carbohydrates, such as bread, rice, or potatoes, our body breaks them down into a sugar called glucose. This glucose is what our cells use to create energy, allowing us to move, think, and carry out all our daily tasks.

But not all carbohydrates are the same. Some, called complex carbohydrates, have extra benefits. Found in foods like whole grains, vegetables, and legumes, they’re made up of longer chains of sugar molecules. Because they’re more complex, our bodies take longer to break them down. This means they give us a steady stream of energy, rather than a quick spike followed by a crash.

Besides providing lasting energy, complex carbohydrates also contain something called fiber. Fiber is a bit like a street sweeper for our digestive system, helping to keep everything moving and clean. It can make us feel full and satisfied, and even support a healthy heart. So, while carbohydrates are often misunderstood, choosing the right ones can support our energy levels and overall health in many ways.

Healthy Choices: Whole grains, fruits, vegetables, and legumes.


First, let’s debunk some diet myths. Fats help us produce hormones. Hormones are like messengers that tell different parts of our body what to do. They control things like growth, mood, and energy. Without fats, our hormones would be all out of whack!

Next, fats are essential for our brains to work properly. Our brains are made up of nearly 60% fat. So, if we don’t have enough healthy fats in our diet, our thinking and memory could suffer.

Lastly, fats are good for our hearts, too. Now, this might sound strange because we often hear about fats being bad for our hearts. But the truth is, there are good fats and bad fats. Good fats, like those found in avocados, nuts, and fish, can actually lower the bad cholesterol in our blood. This helps to keep our hearts healthy and strong.

Healthy Choices: Olive oil, avocados, nuts, seeds, and fatty fish like salmon.


Despite some diet myths, proteins are like the bricks and mortar of our bodies, holding everything together and making sure it all works smoothly. Just like a house needs strong foundations, our bodies need proteins to grow, fix wear and tear, and keep everything running as it should.

Imagine you’re playing with building blocks and creating different shapes and structures. Proteins do something similar in our bodies; they build muscles, help our organs function, and even make our hair and nails strong.

You’ll find proteins in both animal foods, like meat, eggs, and milk, and plant foods, like beans, nuts, and certain grains. This is great because it means almost everyone can get enough protein, no matter what they like to eat.

Some people think that only animal proteins are good, but that’s not true. Even if you’re vegetarian or just prefer eating plants, you can still get all the protein your body needs. The trick is to eat a variety of plant-based foods, so your body gets all the different building blocks it needs.

So, next time you sit down to eat, remember that you’re not just filling your tummy; you’re giving your body the building blocks it needs to keep you strong, healthy, and happy, debunking diet myths along the way. Whether it’s a piece of chicken, a bowl of lentils, or a handful of nuts, you’re helping your body be its best

Healthy Choices: Lean meats, fish, dairy, beans, lentils, and tofu.


The world of nutrition doesn’t have to be confusing. Understanding the science behind carbs, fats, and proteins helps us make informed decisions.


  • Carbs: Not all are bad; choose complex ones.
  • Fats: Include healthy fats; avoid trans and limit saturated fats.
  • Proteins: Balance is key; plant-based proteins can be complete.

Eating right is about balance, variety, and moderation, not fear and misinformation. Consult with a healthcare provider or nutritionist to tailor a plan that fits your individual needs and lifestyle, and embrace the joy of nourishing your body with what it truly needs.

By debunking these myths, we’ve peeled away the confusion, allowing you to embrace a healthier, happier relationship with food. Here’s to enjoying the delicious, nutritious journey that lies ahead!
