The Truth About Carbs, Fats, and Protein: What You Really Need to Know
Let’s get something straight: food is not the enemy.
In fact, if you’ve ever been confused by conflicting headlines or trendy diet rules telling you to cut this, ban that, or survive off air and lemon water—you’re not alone. I’ve been in the health and fitness space for 10 years, both academically and professionally, and if there’s one thing I know for sure, it’s this: food is meant to help you, not hurt you.
When we strip away the noise, nutrition becomes a lot simpler. Carbs, fats, and protein—aka your macronutrients or “macros”—are the foundation of your energy, your recovery, your mental clarity, your hormones, and honestly – your sanity.


Macros are the building blocks to everything we do. However, that doesn’t mean we need to track them obsessively, but instead, we should use them to help us listen to what our bodies actually need.
Don’t know how? That’s why we’re here.
So let’s talk truth. No gimmicks. No fear-mongering. Just the real purpose of food and how you can use macros to feel strong, energized, and balanced in your daily life.
CARBS: YOUR BODY’S GO-TO FUEL
Carbs get a bad rep. Somewhere along the way, they became the villain of every diet headline. But here’s Truth #1: your body loves carbs—and it needs them.
Carbohydrates are your body’s primary source of energy. When you eat carbs, your body breaks them down into glucose, which fuels your brain, muscles, and every single cell in your body.
Yes, even when you’re sitting still—your brain alone uses around 120 grams of glucose per day.

Why You Need Carbs (Through a Scientific Lens):
- Energy & Performance: Whether you’re lifting, running, chasing kids, or just thinking clearly at work—carbs power it all.
- Muscle Recovery: Carbs replenish glycogen stores in your muscles post-workout so you can recover and come back stronger.
- Hormonal Health: Especially for women, under-eating carbs can disrupt thyroid function and stress hormone balance.
- Mood Regulation: Ever been “hangry”? That’s your blood sugar crashing. Carbs help stabilize that, supporting serotonin and mood.
But Not All Carbs Are the Same…
Think quality over restriction. Whole food sources like sweet potatoes, fruit, oats, rice, beans, and whole grains give you fiber, vitamins, and long-lasting energy. Highly processed carbs (think sugary snacks and white bread) aren’t “bad,” but they don’t offer much nutritionally, and leave you feeling empty much more quickly.
Bottom line? Don’t fear carbs. Your body literally runs on them.
FATS: YOUR HORMONE HERO
Next up: fats. Another macro that was unfairly demonized in the low-fat craze of the ‘90s. But now we know better— Truth #2: healthy fats are absolutely essential to a functioning, thriving body.
The role of these healthy fats is support hormone production, brain function, cell health, and nutrient absorption. They also keep you full and satisfied—something a dry salad with no dressing just can’t deliver.
Why You Need Fat (The Experts Say):
- Hormone Production: Your sex hormones (estrogen, testosterone, progesterone) are made from cholesterol and fat. Don’t skimp here.
- Brain Health: Your brain is mostly fat. Omega-3s (from fish, walnuts, flax) actually help your brain cells communicate with each other.
- Vitamin Absorption: Vitamins A, D, E, and K need fat to be absorbed. No fat = missed benefits.
- Anti-Inflammatory Support: Healthy fats help reduce inflammation and support your immune system.

Where to Get Healthy Fats:
Think: avocado, olive oil, nuts, seeds, full-fat dairy, eggs, fatty fish, and yes—even some grass-fed butter or ghee. Focus on whole-food sources over processed oils or trans fats.
Fat isn’t something to avoid. It’s something to use, intentionally and in balance, to support your overall well-being.
LAST BUT NOT LEAST, PROTEIN: YOUR BODY’S BUILDER
If carbs are the fuel and fat is the regulator, protein is the repair crew.
Protein is made of amino acids—little building blocks your body uses for nearly everything: muscle, skin, hair, nails, immune cells, enzymes, hormones. You name it, protein’s involved.
Truth #3: You don’t need to consume insane amounts of protein to get to where you want to be. Protein supports everyone—whether you’re working out, recovering from injury, aging, or just trying to not feel ravenous an hour after lunch.
Why You Need Protein:
- Muscle Maintenance & Growth: Especially important if you’re strength training, active, or aging (muscle loss happens a lot faster than people think).
- Recovery: Protein helps repair tissues after workouts, injury, or illness.
- Blood Sugar Stability: When paired with carbs, protein slows digestion and helps prevent spikes and crashes – meaning you stay full longer & end up eating less.
- Satiety: It’s the most filling macro, which helps you naturally regulate hunger and cravings.
Best Sources:
Chicken, turkey, beef, eggs, Greek yogurt, cottage cheese, protein powders, tofu, tempeh, legumes, seafood—mix it up. Ideally, you want protein with every meal to keep your body fueled throughout the day.
SO HOW MUCH DO YOU NEED?
The short answer: it depends. Everyone’s needs are different based on body size, activity level, goals, and personal history. But general guidelines look like:
- Carbs: 40–60% of total intake (more if you’re active)
- Fats: 20–35%
- Protein: 0.7–1.0g per pound of bodyweight is a solid target, especially if you’re lifting or trying to maintain muscle
You don’t have to track macros forever (or at all) to benefit from understanding them. But if you’ve never tried tracking for a few days, it can be a powerful way to learn where your intake is at and how to make adjustments without guessing.
FOOD IS MEANT TO BE ENJOYED
Let me say it again for the people in the back: food is not the enemy. It’s not a moral scorecard. It’s not something to obsess over or fear.
Food is fuel. It’s connection. It’s comfort, culture, energy, and healing.
When you understand how carbs, fats, and protein each serve you, you stop seeing food as something to control—and start seeing it as something to work with.

You don’t need to cut carbs to lose weight.
You don’t need to fear fat to be healthy.
And you don’t need to eat grilled chicken and broccoli every day to hit your protein goals.
What you do need is:
- A basic understanding of what your body needs
- Trust in how your body responds to different amounts and types of food
- Give yourself permission to enjoy your food—without guilt
Let’s Ditch the All-Or-Nothing Thinking
Nutrition shouldn’t be about extremes. It’s not about perfection. It’s about education, empowerment, and feeling like your best self—in a way that’s sustainable and rooted in reality, not restriction.
So whether your goal is fat loss, muscle gain, hormone support, or just feeling better, start with this foundation: fuel your body well, listen to it often, and give yourself the freedom to enjoy what you eat.
Macros aren’t the answer to everything, but they are an incredible tool to help you find balance, nourish your body, and support your goals—with actual science behind it.
Ready to learn how to fuel your body without the stress, guilt, or confusion? Stick around. There’s a lot more where this came from—and yes, there will be snacks involved.
