And Exactly What to Do Instead
You’ve done your research. You’ve cleared the pantry, stocked up on avocados and bacon, and committed to going keto. And yet — the scale won’t budge, you feel terrible, or you just can’t seem to stay in ketosis. Sound familiar?
Here’s the truth: keto works — but only when it’s done right. The ketogenic diet is one of the most effective tools for weight loss and metabolic health, but it’s also one of the most misunderstood. Small mistakes can completely derail your results, leaving you frustrated and ready to quit.
In this article, we’re breaking down the five most common keto mistakes — the ones that silently sabotage thousands of beginners — and showing you exactly how to fix them. Whether you’re just starting out or you’ve been struggling to see results, this guide is for you.
Mistake #1: Not Eating Enough Fat
This is the single most common mistake we see from keto beginners, and it’s completely understandable. After decades of being told that fat is the enemy, eating 70–75% of your daily calories from fat feels downright terrifying.
But here’s the thing: fat is your fuel on keto. Without enough dietary fat, your body doesn’t have the energy it needs to function — especially when you’ve just taken away its usual source (carbohydrates). The result? Relentless hunger, low energy, and cravings that feel impossible to resist.
Many beginners make the mistake of going “low-carb” but not “high-fat,” essentially eating a calorie-restricted, protein-heavy diet. That’s not keto. You may lose weight short-term from calorie restriction alone, but you’ll miss out on the sustained fat-burning and appetite-suppressing benefits that make keto truly powerful.
The Fix: Embrace Fat as Your Primary Fuel
Aim for fat to make up 70–75% of your total daily calories. This means actively adding fat to your meals — not just tolerating it. Some great ways to boost your fat intake:
- Cook everything in butter, ghee, or coconut oil
- Drizzle olive oil over salads and vegetables
- Add half an avocado to your meals daily
- Use full-fat dairy — heavy cream, cheese, sour cream
- Snack on nuts, seeds, and olives
- Try MCT oil in your morning coffee (“bulletproof coffee”)
If you’re regularly hungry between meals, that’s your body signalling it needs more fat. Don’t be afraid — this is the one diet where eating more fat helps you lose more fat.
Mistake #2: Ignoring Electrolytes
Ask any experienced keto dieter what the #1 cause of misery in the early weeks is, and they’ll almost certainly say the same thing: electrolyte depletion. Yet most beginners never think to address it.
Here’s why it happens: when you cut carbs, your insulin levels drop significantly. Lower insulin signals your kidneys to flush out sodium — and sodium takes potassium and magnesium with it. Within days, you can become severely deficient in these critical minerals, leading to the dreaded “keto flu.”
Symptoms of Electrolyte Imbalance
- Pounding headaches that won’t quit
- Extreme fatigue and muscle weakness
- Painful muscle cramps (especially at night)
- Heart palpitations or a racing heartbeat
- Dizziness when standing up
- Brain fog and difficulty concentrating
- Irritability and mood swings
The Fix: Actively Replace Your Electrolytes
Don’t wait until symptoms appear. Start supplementing electrolytes on day one:
- Sodium: Add 1–2 teaspoons of sea salt or pink Himalayan salt to your food and water daily
- Potassium: Eat avocados, leafy greens, salmon, and mushrooms. Consider a potassium supplement if needed
- Magnesium: Take a magnesium glycinate or citrate supplement (200–400mg/day). It also improves sleep quality
- Drink more water: Aim for at least 2.5–3 litres per day — you’ll lose water rapidly in the early days
Pro tip: A homemade electrolyte drink — water, a pinch of salt, a squeeze of lemon, and a few drops of liquid stevia — costs pennies and is far more effective than most store-bought “keto” products.
Mistake #3: Eating Too Much Protein
Protein is essential — but on keto, more is not better. This is one of the most misunderstood aspects of the ketogenic diet, and it trips up even people who have done their research.
When you consume protein in excess, your body converts the surplus into glucose through a process called gluconeogenesis. Essentially, you’re creating carbohydrates from protein — which can raise your blood sugar, spike your insulin levels, and knock you out of ketosis without a single gram of carbohydrate crossing your lips.
This is a particularly common trap for people who come to keto from the fitness world, where high-protein diets are the norm. Keto is not a high-protein diet — it’s a high-fat diet with moderate protein.
The Fix: Find Your Protein Sweet Spot
Protein should make up roughly 20–25% of your total daily calories. A simpler way to calculate it: aim for 0.7–1.0 grams of protein per pound of lean body mass (not total body weight). For most people, this works out to 75–120 grams per day.
If you’re regularly stalling in weight loss despite eating keto, pull out your food tracking app and check your protein numbers. You may be surprised to find you’ve been eating 150+ grams per day without realizing it. Cut back to the recommended range and see what happens within a week.
Mistake #4: Falling for “Dirty Keto” and Packaged Products
Walk into any health food store and you’ll find entire aisles dedicated to “keto” products: keto bars, keto chips, keto bread, keto ice cream, keto cookies. And while the idea of enjoying your favourite foods guilt-free sounds amazing, these products are often more marketing than magic.
The problem comes in several forms:
- Hidden carbs from ingredients not listed clearly on the front label
- Sugar alcohols like maltitol that still spike blood sugar (and cause digestive distress)
- Highly processed oils and artificial ingredients that trigger inflammation
- Calorie-dense formulas that make it easy to overconsume
- Psychological reinforcement of cravings for sweet and snack foods
“Dirty keto” — hitting your macros with fast food, processed meats, and packaged snacks — may technically keep you in ketosis, but it often leads to stalled weight loss, low energy, and poor overall health.
The Fix: Prioritize Whole, Real Foods
Build the foundation of your keto diet around whole, minimally processed foods. Your staples should be:
- Fatty cuts of meat, poultry, and seafood
- Eggs (nature’s perfect keto food)
- Non-starchy vegetables: spinach, kale, broccoli, zucchini, asparagus
- Healthy fats: avocado, olive oil, coconut oil, butter
- Full-fat dairy: cheese, cream, unsweetened yogurt
- Nuts and seeds in moderation
If you need to use packaged products, flip them over and check the nutrition label carefully. Look at net carbs (total carbs minus fibre) and research any sweeteners used. A good rule of thumb: if you don’t recognise the ingredients, put it back on the shelf.
Mistake #5: Giving Up During the Adaptation Phase
This is the mistake that ends more keto journeys than any other — and it’s heartbreaking, because it happens right before things get good.
The first 2–4 weeks of keto are genuinely difficult for many people. Your body is undergoing a profound metabolic shift — switching from a glucose-burning engine to a fat-burning engine. This transition takes time, and during it, you may feel like you have the flu, have less energy in the gym, and wonder why on earth you’re doing this.
Most people quit somewhere in this window. They feel terrible, they’re not seeing dramatic weight loss yet, and the carbs they used to eat are calling their name. So they throw in the towel — just weeks before their body would have fully adapted.
“Fat adaptation” — the state where your body becomes truly efficient at burning fat and ketones — typically takes 3–6 weeks. Until you get there, you’re in a transition zone that’s genuinely uncomfortable. But on the other side? Sustained energy, mental clarity, reduced hunger, and effortless fat loss.
The Fix: Commit to 6 Weeks — No Matter What
Make a deal with yourself: you will not judge keto’s effectiveness until you’ve completed at least 6 full weeks of strict adherence. Here’s how to make it through:
- Fix your electrolytes — this alone eliminates most of the early discomfort
- Track your food — use an app like Carb Manager to ensure you’re actually hitting your macros
- Reduce exercise intensity temporarily — your body is adapting; intense workouts during this phase can be counterproductive
- Track non-scale victories — better sleep, clearer skin, reduced bloating, and steadier energy are all signs it’s working
- Find your community — join a keto Facebook group, subreddit, or find a keto buddy. Accountability is everything
Remember: every person who swears by keto once felt exactly how you feel right now. The difference between them and the people who gave up? They pushed through.

The Bottom Line
Keto isn’t complicated, but it is precise. The difference between struggling on keto and thriving on keto often comes down to a handful of small, fixable mistakes.
Eat enough fat. Replace your electrolytes. Don’t overdo the protein. Ditch the processed keto junk. And above all – give your body the time it needs to adapt. Do these five things consistently, and you’ll experience keto the way it’s meant to feel: effortless fat loss, boundless energy, and a clarity of mind you didn’t know was possible.
Don’t think you’re failing at keto. You may just need to fix one of these five mistakes – and everything can change.
