Are carbs bad for you?

If you’ve ever wondered this, you’re not alone. Thanks to years of diet culture and persistent carb myths, many people are cutting carbs—fearing they’ll gain weight, spike blood sugar, or lose control around food.

But the truth is, carbs are essential for your energy, metabolism, and mental clarity. And cutting them out based on outdated carb myths often leads to more harm than good.

In this blog post, we’ll bust the 4 most common carb myths—and show you what actually happens when you eat carbs as part of a balanced diet.

If you’ve been avoiding bread, pasta, or fruit because of these carb myths, keep reading. You might be surprised by what you learn.

What Are Carbohydrates?

Carbohydrates (carbs) are one of the three macronutrients—along with protein and fat—that your body needs to survive. They’re found in:

• Grains (like bread, rice, oats, pasta)
• Fruits and starchy vegetables (potatoes, corn, peas)
• Legumes (beans, lentils)
• Dairy (milk, yogurt)

When you eat carbs, your body breaks them down into glucose—your brain and muscles’ preferred source of fuel.

Are Carbs Bad for You?

Let’s clear this up right now: No, carbs are not bad for you.

Your body actually needs carbohydrates to function. In fact, when clients in my practice start eating more balanced meals—including carbs—they usually notice less fatigue, fewer cravings, better digestion, and improved mood.

Yes, some carbs offer more fiber and nutrients than others—but that doesn’t mean foods like white bread or cookies are “bad.” All carbs can fit into a balanced eating pattern.

Carb Myth #1: Carbs Make You Gain Weight

This is one of the most common carb myths I hear.

Here’s the truth: Carbs don’t cause weight gain—overeating in general does.

Low-carb diets became popular in the early 2000s, and since then, many people have blamed carbs for everything from weight gain to fatigue. But the science doesn’t back this up.

In fact:

• Cutting carbs often leads to deprivation and cravings, making it harder to maintain balanced eating long-term.
• When you cut carbs, your body initially loses water weight, which can make it look like you’re losing fat—but that weight comes back as soon as you start eating carbs again.
• Carbs are your body’s primary energy source—drastically cutting them can leave you feeling exhausted, moody, and constantly thinking about food.

If you’re tired of fearing bread or pasta, here’s what works instead:

• Include carbs in your meals every 3-4 hours to keep your energy steady and prevent cravings.
• Pair carbs with protein and fat (e.g., whole-grain toast with peanut butter, or rice with chicken and avocado) to help with fullness and satisfaction.
• Stop labeling carbs as “bad”—when you allow yourself to eat them regularly, they lose their power over you.

Real Client Win: Kathryn

When Kathryn started working with me, she was afraid to eat carbohydrates because of previously having gestational diabetes. Once I gave her a structured meal plan and educated her about how different foods affect her body, she started eating more consistent, balanced meals and snacks. Not only did she lose weight, but she also improved her blood glucose control, lowered her cholesterol, and stopped feeling guilty after eating.

Carb Myth #2: Carbs Spike Your Blood Sugar and Are “Bad” If You Have PCOS or Diabetes

Another big carb myth is that people with insulin resistance or diabetes should avoid carbs completely. But that’s not only unnecessary—it can actually make things worse.

Cutting out carbs completely can leave you feeling tired, constantly thinking about food, and struggling with cravings. And then, when you finally do eat carbs, you overdo it because you feel so deprived.

And if that’s not enough, here are three reasons why completely avoiding carbs isn’t the solution:

• Your body needs carbohydrates to function. Your brain and muscles rely on glucose (from carbs) for energy. Completely cutting them out can lead to fatigue, brain fog, and mood swings.
• It can lead to more intense cravings and overeating. Many people who try to eliminate carbs end up binging on them later, which can cause even bigger blood sugar fluctuations.
• Not all carbs affect blood sugar the same way. Whole grains, fruits, and fiber-rich carbs help stabilize blood sugar when paired with protein and fats, rather than causing extreme highs and lows.

Instead of avoiding carbs, focus on how and when you eat them:

• Eat carbs every 3-4 hours to avoid extreme hunger and blood sugar crashes.
• Pair carbs with protein and fat—for example, have whole-grain toast with eggs, or oatmeal with nuts and Greek yogurt.
• Focus on fiber-rich carbs like quinoa, brown rice, sweet potatoes, and beans, which help slow digestion and keep you full longer.

Real Client Win: Lisa

Lisa had tried every diet and still struggled with cravings and blood sugar spikes. When we focused on sustainable eating (with carbs!), she lowered her A1c to 4.8% and felt more energized and confident than ever.

Carb Myth #3: You’ll Have More Energy Without Carbs

One of the most persistent myths about energy and mental clarity is the idea that cutting out carbs will help you feel more focused and energized.

So not true! Carbs actually help your brain function optimally. Just not the way you might think.

Carbohydrates are your brain’s preferred energy source, and your body relies on them to keep your blood sugar stable, support focus, and prevent energy crashes.

When you eat carbs in a balanced way, they actually help stabilize energy levels and improve concentration. Studies show that glucose from carbohydrates fuels cognitive function, while extreme carb restriction can lead to brain fog, irritability, and fatigue.

So Why Do Some People Say They Feel Better Without Carbs?

If you’ve ever felt sluggish after eating carbs, it’s likely not the carbs themselves—but how you’re eating them.

Here’s what might actually be happening when people say carbs make them feel tired:

• They’re eating mostly refined carbs without protein or fat or going too long without eating, leading to a blood sugar spike followed by a crash.
• They’re under-eating in general, which can cause fatigue no matter what.
• They’ve convinced themselves that carbs are “bad,” so they expect to feel sluggish after eating them.

What to Do Instead

If you want steady energy and mental clarity without cutting carbs, here’s what actually works:

• Eat carbs regularly throughout the day—not just in one big meal. This prevents energy dips and brain fog.
• Pair carbs with protein and fat to slow digestion and keep your energy stable. Think: oatmeal with nuts and yogurt or toast with eggs and avocado.
• Choose fiber-rich carbs like whole grains, fruits, and legumes for longer-lasting energy.

Real Client Win: M’s Story

Client M had been on every diet under the sun, each one reinforcing the idea that carbs were “bad.” When we started working together, she felt out of control around food, constantly craved sweets, and had low energy.

Once we incorporated more carbs into her diet, her energy levels stabilized, her carb cravings decreased, and—most importantly—she felt more in control around food. Now, she’s no longer snacking chaotically and finally feels empowered around eating.

Carb Myth #4: Cutting Carbs Will Help You Stop Binge Eating

If you’ve ever cut out carbs hoping it would “fix” your cravings, you’re not alone.

But here’s the deal: Restricting carbs increases cravings—and makes binge eating more likely.

Why?

• Your body craves what it’s missing. If you cut carbs, your brain will keep sending signals to eat them. This isn’t a lack of willpower—it’s biology.
• Low energy triggers cravings. Carbs are your body’s primary energy source. Without enough, you’ll feel exhausted, which can make cravings feel overwhelming.
• The “forbidden food” effect. When you tell yourself you can’t have something, it becomes all you think about—leading to a binge later on.

What to Do Instead

If you want to feel in control around carbs and stop binge eating, here’s what actually works:

• Eat carbs within 2 hours of waking up and every 3-4 hours after that to keep your blood sugar stable and prevent extreme hunger.
• Pair carbs with protein and fat (think: toast with peanut butter, or rice with salmon and avocado) to increase satisfaction and prevent cravings.
• Stop labeling carbs as “bad.” When you allow yourself to eat them regularly, they lose their power over you.

A simple step you can take today? Prioritize eating carbs and breakfast and lunch (paired with protein and fat, of course!) and notice how it impacts your cravings later.

Shelby thought carbs were causing her to overeat at night. But after working together to create a more balanced meal schedule (which included carbs!), she stopped binge eating and started feeling energized and satisfied throughout the day.

Why Carbs Don’t Cause Weight Gain (and What to Do Instead)

If you take away one thing from this post, let it be this: Carbs don’t make you gain weight. 

When you eat carbs in a balanced way:

• Your energy stabilizes
• Cravings become manageable
• You feel more in control of food

Instead of fearing carbs, start listening to your body, eating consistently, and letting go of food rules that don’t serve you.
