🥓 5 Ways to See If You’re in Ketosis (Without Losing Your Mind)

So you’ve waved goodbye to toast, turned down the chips, and bravely passed the biscuit tin like a warrior in battle. But now what?

You’re doing all the keto things — but how do you actually know if your body’s flipped the fat-burning switch?

Here are 5 ways to check if you’re in ketosis — no guesswork, no nonsense, and definitely no licking your palm to “taste the ketones.” (Yes, that’s a thing. No, we’re not doing it.)

1️⃣ Pee Strips: The OG Keto Test

Ketone urine strips are basically your training wheels when starting keto. You pee on one, wait a few seconds, and voilà — if the strip turns pink or purple, your body’s chucking out ketones. You did it!

🔍 Why it works: In early ketosis, your body produces extra ketones it hasn’t learned to use yet — so it ditches them in your pee.

🟢 Good for: Keto newbies who want proof it’s working.
🔴 Not ideal if: You’ve been keto for a while — your body gets more efficient, and you’ll stop peeing out excess ketones.

💡 BBK tip: Don’t obsess over how dark the strip turns. Dehydration can make it look like you’re in mega-ketosis when you’re just low on water.

2️⃣ Funky Breath: The “Keto Cough Drop” Effect

One day you’ll be minding your own business, brushing your teeth, and then — BAM — you’ll catch a whiff of something… weird. Fruity. Slightly chemical-y. Welcome to keto breath.

🔍 Why it happens: Your body is releasing acetone, one of the ketones, via your breath. Kind of gross. Also kind of exciting.

🟢 Good for: That weird-but-cool “ahh, it’s happening” moment.
🔴 Not ideal if: You like to keep your breath minty-fresh at all times. (Mints are fine — just avoid the sugary ones.)

💡 BBK tip: If your dog looks mildly offended when you talk to them, congrats — you might be in ketosis.

3️⃣ Brain On Fire (In a Good Way)

One of the best perks of ketosis? That clean, smooth, no-crash energy. It’s like your brain stopped running on supermarket diesel and switched to rocket fuel.

🔍 Why it works: Ketones are a more efficient fuel for your brain. Many people feel clearer, sharper, and less foggy.

🟢 Good for: Anyone who wants to feel like a productivity ninja.
🔴 Not ideal if: You’re still in the “keto flu” phase (hang in there — it gets better).

💡 BBK tip: Notice when you stop reaching for that mid-afternoon coffee… and you’re still ticking along like a champ.

4️⃣ Hunger? What Hunger?

If you suddenly realise it’s 2pm and you haven’t even thought about lunch — congrats. You’re probably burning fat and feeling full on fewer meals.

🔍 Why it works: Ketosis naturally suppresses your appetite. Hormones like ghrelin (the hunger gremlin) take a back seat.

🟢 Good for: Feeling like a snackless superhero.
🔴 Not ideal if: You forget to eat altogether — fuel up, even if you’re not ravenous.

💡 BBK tip: Eating less often doesn’t mean eating less food. Still get those nutrients in, friend.

5️⃣ The Gold Standard: Blood Ketone Meter

Okay, this one’s for the numbers people. If you love a chart, a graph, or a good finger prick — the blood ketone meter is your bestie.

🔍 Why it works: It measures beta-hydroxybutyrate (BHB) — the main ketone in your blood — giving you an accurate ketosis readout.

🟢 Good for: Serious trackers, diabetics, or those on therapeutic keto.
🔴 Not ideal if: You faint at the sight of your own blood or hate spending money on test strips.

💡 BBK tip: A reading of 0.5 to 3.0 mmol/L means you’re in ketosis. But remember: how you feel matters just as much.

🧀 Final Thoughts: It’s Not Just About the Numbers

You don’t have to test. If you’re feeling clearer, less snacky, and like a legend for skipping the bread basket — that’s your body saying: “Yep. We’re in.”

Whether you’re peeing on sticks, logging numbers, or just vibing with your ketones, trust the process. You’ve got this.
