Do Carbs Make You Fat?

Seemingly every new fad diet, such as the popular keto and paleo diets, seems to have one thing in common: low carbs. While these trends promise weight loss, before we say goodbye to our favorite bread and granola, let’s pause and ask the question, “Do Carbs Make You Fat?” We jump into the research to answer this question once and for all. Good news! You’re going to like this answer.

First, What Are Carbohydrates?

Before we begin, we need to clear up a misconception. Carbohydrates are one of three macronutrients, alongside fats and proteins. That means that carbohydrates cover a wide range of food — and it’s not just the cakes, breads, pastas, and potatoes that most think of. Vegetables, beans, and fruits are carbohydrates, too. 

As the primary energy source for the human body, your body needs carbohydrates to survive, thrive, repair, and grow. Once eaten, carbohydrates convert to glucose, which enters the bloodstream and provides energy throughout the whole body. Fun fact, 25% of this energy goes straight to your brain. Yup, your 3-pound brain takes up a quarter of your energy!

Why Do Diets Restrict Carbohydrates?

So, if carbohydrates include healthy foods like vegetables and beans, why do all of these diets restrict them? Just as protein is glorified in the modern Western diet, carbohydrates are equally vilified. What’s more, this isn’t anything new. Low-carb diets have been touted for weight loss since the early 1900s.

The theory of the ketogenic diet, a more modern trend, is to have stored fat burned instead of carbohydrates to lose weight. To get your body to burn fat in the required metabolic state of ketosis, there can’t be carbohydrates available. So, if you restrict your carb intake, your body starts converting its stored fat into energy and dieters lose weight.

Yes, this is all true, but before you have dreams of dumping butter all over your bacon-covered strip steak, we have to remind you of one thing: your body needs carbohydrates. Your brain needs carbohydrates.

Losing weight is essential if excess weight is hurting your health, but too often we see the “low carb” blanket falling into dangerous territory. A typical ketogenic dieter will only eat 20 grams of carbohydrates a day — about the amount in one medium-sized potato.

The thing is, with carbohydrates also in fruits, beans, and vegetables, we too often see those healthy, fiber-filled whole foods cut out to make the 20-gram number. So let’s not rush to use a quick-fix for weight loss that simultaneously hurts your health, because losing weight isn’t worth it when you damage your body and brain.

This leads us to the main question that we hear almost weekly, “Do carbs make me gain weight?”

Do Carbs Make You Fat?

“If carbs make you fat, then 2 billion people in China never got the message about that.” – Dr. Pamela Popper, author of Food Over Medicine

Have you been to China? We lived there for three years, and they are not fat.

The devil is in the details with carbohydrates. If we’re talking about eating processed, simple carbohydrates filled with refined sugar and corn syrup then, yes,  these carbs will make you gain weight. Examples are soda, cake, pizza, french fries, and white bread. Not only will they make you fat, but these fake foods also make you sick.

Complex carbohydrates, on the other hand, encompass most fruits, vegetables, whole grain products, and legumes (beans, lentils, chickpeas). You can eat these almost without limit (some doctors recommend up to 900 grams of these carbohydrates!) because they will satiate you before making you fat.

So here’s your answer: NO! Carbs do not make you fat. Instead, just fat makes you fat. Aiming to eat a diet full of healthy, complex carbohydrates is the best possible thing you can do. 

“At least 80% of your calories should come from complex carbohydrates. We need glucose, our brains run on glucose. Carbohydrates make you thin. All the healthy nutrient populations around the world eat a predominantly plant-based, high-carb diet. The longest living people in the world, Okinawans, eat, I believe, 72% of the calories from carbs in the form of sweet potatoes.” – Chef AJ, celebrity chef and author of Unprocessed

Pro Tip: A good rule of thumb to figure out if the carbohydrates in your pantry are unhealthy is to take a look at the fiber content. We purchase only granolas, pastas, and tortillas that contain at least 1 gram of fiber per 10 grams of carbohydrates. White bread is simply fiberless whole wheat bread, and white rice is fiberless brown rice.

Are There Risks to Low Carb Diets?

While many see immediate weight loss benefits from a carb restrictive diet, longterm studies show that it is neither healthy nor sustainable. As a renowned plant-based physician Dr. Milton Mills puts it, “Low carb foolishness… low-carb dieters are at higher risk for chronic disease, poorer performance on mental function, and greater risk of all-cause mortality.”

Outside of this, the sustainability for highly-restrictive diets is low with many stories of dieters bouncing back to regain an additional 10-15% of their original body weight from before the diet. We discuss this extensively in our article, The Problem With Fad Diets. Including, why losing weight on a restrictive diet slows down your metabolism and unhealthily alters your body’s leptin hormone sensitivity. 

Another risk is poor digestion. After all, fiber is a type of carb.

Why We Don’t Low Carb Diet

Chances are, your low carb diet is going to help you lose weight… at first. But take a close look at how you feel. Deprived? Still hungry? Cravings? Low energy? Is it sustainable? It’s not. 

Let us sum up the one main reason we have never jumped aboard the low carb diet bandwagon. 

Evidence Supporting Low Carb:

150 years of low carb diet data construed by 75 years of people consuming processed, manufactured carbs. The data shows mixed benefits, potentially because the scientists were funded by food lobbyists or supplement/diet companies. Furthermore, even good science collects data from a sample set of people who were consuming large amounts of unhealthy processed carbs. The studies help sick people who want to be less sick, not sick people who want to be healthy.

Evidence Supporting Healthy Carbs:

Thousands of years data on populations that eat lots of healthy carbohydrates. There are current non-western populations that are compared side-by-side to populations eating a modern, western diet of processed carbs. The benefits are infallible — complex, healthy carbs are a staple among the healthiest, longest living populations. Eating more veggies, beans, fruits, nuts, grains, and seeds are the foods that help sick people become healthy.

We can learn a lot from the healthiest cultures in the world. If you need more evidence, look no further than the five Blue Zone populations of Okinawa, Icaria, Nicoya, Sardinia, and Loma Linda.

Our Personal Approach to Carbohydrates

We both agree that balance is critical when it comes to both simple and complex carbohydrates. While we’ve fully cut-out many simple carbohydrates and refined sugars, there are still some that we love, including pies, cookies, maple syrup, honey, and chocolate. Our saving grace here is to do our best to limit their consumption and try to keep them out of the cupboards.

Instead, we fully embrace our complex carbs and don’t bother to count them. We also simultaneously try to eat our carbohydrates early in the day and finish by lunch. Knowing that carbohydrates are our main energy source, we choose not to energize ourselves right before bed!

So in a nutshell, aim to eat lots of whole grain products, legumes, vegetables, and fruit and we manage our diets as a couple to make sure we are getting the proper portions. Learning how to fuel your body properly takes time and practice. So, make sure you are clear as day on your Why to live a healthy life. And make sure your partner is on board. If you’re carb rules and health goals are not aligned that’s a big problem.
