First, a Quick Reality Check on Keto

The ketogenic diet is a very low-carb, higher-fat way of eating. When you cut carbs low enough, your body shifts to burning fat for fuel and makes ketones — a backup energy source. That state is called ketosis, and it’s where the diet gets its name.

Some people lose weight and feel more even-keeled on keto. Others find it too strict to stick with, or feel worse on it. Neither makes you a failure. After 20+ years of coaching, I’ve learned there’s no one-size-fits-all plan — but there are common mistakes that make keto harder than it needs to be. Let’s fix them.

Sign 1: You Feel Awful All the Time

This is the big one. Many people start a low-carb diet, feel wiped out within a few days, and assume that’s just “how keto feels.” It isn’t. That headache, brain fog, and fatigue has a nickname — the keto flu — and it’s usually not the diet itself. It’s a lack of fluids and electrolytes (minerals like sodium, potassium, and magnesium).

Here’s why: when you slash carbs, your body flushes out water fast, and important minerals go with it. That’s what leaves you dragging.

The Fix

Drink plenty of water, and don’t be afraid to salt your food a little more than usual. Eating mineral-rich foods like leafy greens, avocado, and nuts helps too. If you still feel rough after a couple of weeks, that’s your body telling you something — listen to it, and check in with a professional.

Sign 2: Hidden Carbs Are Sneaking Onto Your Plate

You think you’re low-carb, but the scale won’t budge and you never quite feel “in ketosis.” The culprit is often carbs you didn’t count. They hide in sauces, dressings, “sugar-free” snacks, starchy vegetables, and drinks you’d never suspect.

Ever check the label on a bottled salad dressing or a flavored coffee creamer? The sugar adds up fast. A little here and there can quietly keep your body running on carbs instead of fat.

The Fix

Get in the habit of reading labels, especially on anything packaged. Watch for sneaky sugar in condiments, marinades, and beverages. When you cook from whole ingredients, you always know what’s on your plate — no surprises.

Sign 3: You’re Terrified of Protein

Here’s a myth worth clearing up. Somewhere along the way, keto got a reputation as a “fat-only” diet, and people started avoiding protein because they heard it “kicks you out of ketosis.” For most people, that’s simply not true.

Your body doesn’t flip protein straight into fat-burning sabotage. In fact, getting enough protein is one of the most important things you can do on any weight loss plan. It protects your muscle, keeps you full, and supports your metabolism. Skimp on it, and you may lose muscle along with fat — which is the last thing you want.

The Fix

Don’t fear protein. Build your meals around quality sources like eggs, fish, poultry, and meat, and let fat play a supporting role rather than the whole show. This matters even more for women in perimenopause and menopause, when holding onto muscle gets harder. Isn’t it a relief that you don’t have to choke down butter by the spoonful?

Sign 4: Your Plate Has No Vegetables

Somewhere in the bacon-and-cheese excitement, a lot of people forget the veggies entirely. Then they wonder why they feel backed up, tired, and generally “off.” Low-carb doesn’t mean no plants.

Vegetables give you fiber, which keeps digestion moving and helps you feel full. They also deliver vitamins and minerals you can’t get from meat and cheese alone. Skip them for too long, and constipation and nutrient gaps often follow.

The Fix

Load up on low-carb, above-ground vegetables — leafy greens, broccoli, cauliflower, zucchini, peppers, and mushrooms. They fit easily into a keto plate and make your meals more colorful, filling, and nourishing. Think of veggies as the base, not an afterthought.

Sign 5: You’re Living on Processed “Keto” Products

Walk down any grocery aisle and you’ll find keto cookies, keto bars, keto bread, and keto candy. They’re convenient, sure. But building your diet around ultra-processed “keto” products is one of the most common ways to stall your results.

These foods are often packed with additives, sugar alcohols that upset some stomachs, and calories that add up fast. They can also keep your sweet cravings alive, which makes the whole thing harder. Just because something says “keto” on the box doesn’t make it healthy.

The Fix

Treat those products as occasional conveniences, not daily staples. Anchor your eating in whole foods and healthy fats — eggs, fish, avocado, olive oil, nuts, and plenty of vegetables. Your body knows what to do with real food. 💡

Sign 6: You’re Obsessed With Ketone Numbers, Not How You Feel

Some people get so wrapped up in testing strips and ketone readings that they miss the bigger picture. They chase a number on a meter while ignoring their energy, sleep, mood, and hunger — the things that actually tell you whether a way of eating is working for you.

Ketosis is a tool, not the goal. The real goal is feeling healthier, having steady energy, and building habits you can keep. Does it matter if you’re in “deep ketosis” if you feel miserable and can’t sustain it?

The Fix

Pay more attention to how you feel and function than to any single reading. Are you sleeping well? Is your energy steady? Are your cravings calmer? Those signals matter far more than a strip that changes color. Progress you can feel beats a number you’re chasing.

Sign 7: You Skipped the “Check With a Doctor First” Step

This is the sign people most want to ignore — and the most important one. Keto is a big change, and it isn’t safe or appropriate for everyone. Starting it blindly can cause real problems for some people.

You should talk to a doctor before trying keto if you’re pregnant or nursing, have kidney or liver conditions, take medication for diabetes or blood pressure, or have a history of disordered eating. For people on certain blood-sugar medications especially, going very low-carb without guidance can be dangerous.

The Fix

Get a green light before you dive in, especially if you manage any health condition. A doctor or registered dietitian can help you decide whether keto fits your body and your life — or whether a gentler low-carb or Mediterranean approach might serve you better.

Doing Keto Right vs. Doing Keto Wrong

Doing Keto Right ✅	Doing Keto Wrong ❌
Drinking water and replacing electrolytes	Powering through the “keto flu”
Reading labels for hidden carbs	Guessing and hoping
Eating enough quality protein	Fearing protein and losing muscle
Filling half the plate with veggies	Skipping plants entirely
Building meals from whole foods	Living on packaged “keto” snacks
Tracking how you feel	Obsessing over ketone strips
Checking with a doctor first	Diving in with a health condition

Actionable Tips to Get Back on Track This Week

Pick one or two of these to start — you don’t need to fix everything at once:

• 💡 Add salt and water. If you feel drained, hydrate and lightly salt your food before assuming keto “isn’t working.”
• 💡 Audit three labels. Check your dressing, creamer, and favorite snack for hidden carbs and sugar.
• 💡 Put a veggie on every plate. Make greens or broccoli your default side.
• 💡 Choose one whole-food swap. Trade a packaged keto bar for eggs, nuts, or avocado.
• 💡 Check in with yourself daily. Rate your energy, sleep, and cravings instead of chasing a ketone number.
• 💡 Book a quick chat with your doctor if you take any medication or manage a health condition.

The Bottom Line

If keto has left you feeling worse instead of better, you’re probably not failing — you’re just running into one of the 7 signs you’re doing keto wrong. The good news is that every one of them has a simple fix, and none of them require more willpower. They just require a little more know-how.

Remember, keto is one tool among many, not the only path to sustainable weight loss. Whether you stick with a low-carb approach or find something that fits your life better, steady, livable habits will always beat a strict plan you can’t maintain. Be patient with yourself, adjust as you go, and trust that small, smart changes add up. You’ve got this. 💪
