For years, carbohydrates have been demonized by diet culture, often labeled as the primary cause of weight gain. From low-carb diets to the keto craze, carbs have had a rough reputation. But are they truly the enemy? In reality, carbohydrates are a crucial component of a balanced diet, despite the trends that promote cutting them out entirely.

According to the Dietary Guidelines for Americans, carbohydrates should account for 45-60% of your daily caloric intake. Not all carbs are created equal, though. While we all enjoy a sugary treat like a donut, it's important to consider how different types of carbohydrates impact our health, especially for those mindful of their blood sugar.
Let’s break down why carbohydrates matter, how they support different health goals, and the best types to include in your diet using the Problem-Agitate-Solution (PAS) framework.
The Problem: Misunderstanding Carbs and Their Role in Health
Carbohydrates come in two primary forms: simple and complex. Simple carbohydrates are quickly digested and offer fast energy but can cause blood sugar spikes. These are the sugars and refined grains we often associate with unhealthy eating. On the other hand, complex carbohydrates take longer to digest due to the presence of fiber, vitamins, and other nutrients, making them a much better choice for sustained energy.
Unfortunately, diet culture has villainized all carbs equally, leading to confusion about their role in weight management, athletic performance, and overall health. People often turn to extreme low-carb diets in an effort to lose weight or improve their health without fully understanding the risks. But what happens when you eliminate carbs entirely?
Agitation: The Consequences of Cutting Carbs
Cutting carbs completely can have significant negative consequences. Carbohydrates are the body's preferred energy source, especially for the brain and muscles. Without enough carbs, the body has to rely on other, less efficient energy sources like fats and proteins. This can lead to several problems:
Metabolic Slowdown: When you don’t consume enough carbohydrates, your metabolism can slow down. This is the body’s way of conserving energy, but it works against anyone looking for sustainable weight loss.
Muscle Breakdown: Without carbs, your body might break down muscle tissue to get the energy it needs, leading to muscle loss, which is the opposite of what most people want when trying to get healthier.
Energy Deficiency: Especially for athletes, not having enough carbs in your system can leave you feeling fatigued and unable to perform at your best.
Digestive Issues: Carbohydrates, particularly those high in fiber, are essential for good digestion. Without enough fiber, many people experience constipation or other gastrointestinal issues.
Registered dietitian McKenna Welshans emphasizes that while it’s important to avoid excess carbohydrates, going too far in the opposite direction can be just as detrimental. “An insufficiency in carbohydrates can cause metabolic slowdown and excess muscle breakdown, which works against sustainable weight loss.”
So, how can you strike the right balance? Let’s take a closer look at how to incorporate the right kind of carbs into your diet for different health goals.
Solution: Choosing the Right Carbs for Your Goals
1. The Best Carbs for Weight Loss
You might think that weight loss requires cutting carbs, but that’s not the case. Eliminating carbohydrates altogether can harm your metabolism and energy levels. Instead, focus on high-fiber and whole food-sourced carbohydrates. These types of carbs help keep you full, prevent blood sugar spikes, and work in tandem with lean proteins and healthy fats for a balanced diet.
According to Welshans, “Carbohydrates, when paired with protein and fats, prevent blood sugar spikes and crashes, keeping your energy levels steady and supporting sustainable weight loss.”
Try this:
A fruit smoothie with frozen berries, bananas, spinach, and Greek yogurt
A mid-morning snack of trail mix with nuts and dried fruit
An apple with nut butter for sustained energy
2. The Best Carbs for Athletic Performance
Athletes often focus on protein, but carbohydrates are actually the body’s primary source of energy for high-intensity exercise. Carbs fuel glycogen stores, which provide energy for endurance and strength-based activities. Before a big event, many athletes engage in carb-loading, eating foods like pasta or grains to boost these glycogen reserves.

Post-workout, carbs are equally important for recovery. According to the National Academy of Sports Medicine, a 150-pound athlete needs between 68 to 102 grams of carbs post-workout to replenish glycogen stores and promote recovery.
Try this:
Granola bars or grain-based snacks like crackers can be easy on your stomach during a long workout
Simple carbs like sports gels and candy can offer quick energy during prolonged exercise
3. The Best Carbs for Heart Health
We’ve all heard about fiber being good for digestion, but did you know it’s also key for heart health? Fiber, particularly soluble fiber, helps lower LDL cholesterol (the “bad” cholesterol) and stabilizes blood sugar levels by slowing digestion.
Registered dietitian Mary Ellen Phipps explains that soluble fiber binds to cholesterol in the digestive system, preventing it from being absorbed into the bloodstream. A 2019 study confirmed that soluble fiber helps reduce blood cholesterol levels, supporting cardiovascular health.
Try this:
Oats, beans, apples, pears, lentils, and peas are excellent sources of soluble fiber that promote heart health
4. The Best Carbs for Blood Sugar Control
For people who struggle with blood sugar fluctuations, carbs can either be your best friend or worst enemy, depending on the type you choose. Simple, refined carbs cause blood sugar to spike and then crash, leaving you feeling sluggish. On the other hand, complex carbohydrates digest slowly, providing steady energy without the rollercoaster of sugar highs and lows.
Registered dietitian Kim Rose Francis recommends increasing your intake of high-fiber carbs gradually, which will help moderate blood sugar levels. “Fiber is a type of carbohydrate the body cannot digest and, hence, can help moderate blood sugar levels,” she explains.
Try this:
Choose a breakfast cereal that contains at least 5 grams of fiber per serving
Opt for bread or grains that have at least 3 grams of fiber per serving
5. The Best Carbs for Digestive Health
Yes, we’re talking about fiber again. Fiber is a crucial component of carbohydrates that plays an essential role in maintaining a healthy digestive system. It helps keep things moving through your intestines by adding bulk to your stool, and it also feeds beneficial bacteria in your gut.
Welshans notes that while fiber is incredibly important, too much fiber can lead to digestive issues like bloating, constipation, or diarrhea. The key is balance.
The American Heart Association recommends that adults aim to consume 25 to 38 grams of fiber daily. You can easily meet this goal by incorporating whole grains, fruits, and vegetables into your meals.
Try this:
A daily meal plan could include 1 cup of brown rice (3.5 grams of fiber), 1 apple (4.4 grams of fiber), 2 cups of veggies (16 grams of fiber), and a half-cup of beans (7 grams of fiber)
Conclusion: Carbs Are Not the Enemy
The myth that carbs are bad for you is exactly that — a myth. When chosen wisely, carbohydrates can be an incredibly beneficial part of your diet, supporting everything from weight loss and athletic performance to heart health and digestion. The key is to focus on whole, unprocessed carbohydrates and to avoid refined sugars and simple carbs that cause energy crashes and health problems.
Remember, carbohydrates should be an essential part of your diet, not something to fear. By incorporating the right types of carbs, you can fuel your body, protect your heart, and feel your best every day.
