Fast Like a Boss: What Happens at 24, 36, 48, and 72 Hours of Fasting

Okay, real talk:

Fasting isn’t just some ancient monk thing — it’s your body’s glow-up button.

When you stop eating for a little bit (or a lotta bit), your body stops just surviving and starts thriving.

Let’s break down what actually happens when you fast — and why every hour you're NOT eating is your body’s version of "thank you, queen"

24 Hours In: Sugar? We Don’t Know Her.

By the 24-hour mark, your body is officially DONE with sugar drama.It’s burned through all the quick energy (glucose) you had stored and now it’s eyeing your fat like, “You’re next.”

At 24 hours you’re:

• Burning fat for energy (hi, ketosis!)

• Lowering blood sugar and insulin (byyyye cravings)

• Boosting human growth hormone (aka muscle repair and youthful skin magic)

• Starting a little cellular clean-up party (autophagy) — because why not?

You might feel:A little hangry... but also low-key sharper than usual. Stick with it, babe.

36 Hours In: Fat Burn Is On Fire

At 36 hours, you’re not just burning fat — you’re basically melting it.Your body is now fully team “use fat for fuel.”

At 36 hours you’re:

• Burning even deeper fat stores

• Turning down inflammation (goodbye puffy face)

• Boosting brain power (hello, genius)

• Cleaning out dead/damaged cells like a ruthless boss

You might feel:Honestly? Pretty damn good. Hunger comes in waves but the mental clarity is real.

48 Hours In: Anti-Aging CEO Mode

You’ve officially entered "Benjamin Button" territory.Your body is deep cleaning EVERYTHING.Cells? Renewing. Inflammation? Dropping. Skin? Glowing. Energy? Weirdly bomb.

At 48 hours you’re:

• Deep in autophagy — your body’s Marie Kondo-ing your insides

• Killing off old zombie cells (the ones that make you look and feel old)

• Healing your gut

• Flexing with sky-high growth hormone (hair, nails, skin, joints say thank you)

You might feel:Kinda unstoppable. Kinda ready to run a Fortune 500 company.

72 Hours In: Full-Body RESET

Three days in and guess what?Your body isn’t mad at you — it’s giving you a standing ovation.

At 72 hours you’re:

• REBUILDING your immune system (brand new white blood cells, baby)

• Repairing deep tissues and organs

• Erasing insulin resistance

• Burning stubborn fat like a flamethrower at a birthday party

You might feel:Light, clear, proud, and a little bit like a superhero. (Because you ARE.)

Bottom Line:

Fasting is basically your body’s secret weapon:

• Burn fat

• Heal from the inside out

• Boost your brain

• Glow like a fresh croissant out the oven

Whether you do a quick 24-hour flex or go for the full 72-hour superhero status, every hour your body is busy making you better.

You’re not starving — you’re EVOLVING.

Stay hydrated, stay sassy, and let your body do what it was built to do.

Tips to Make Fasting Easier (So You Don’t Hate Life)

1. Hydration is QueenWater isn’t optional — it’s your BFF during a fast.Drink water like it’s your side hustle. Add a pinch of pink salt or electrolyte drops to keep your energy and mood steady.(Otherwise, hello headaches and crankiness.)

2. Coffee + Tea Are Your WingmenBlack coffee, green tea, and herbal teas are totally fair game.Caffeine suppresses appetite and gives you a little I’m not dying boost.(No milk, no sugar — don't play yourself.)

3. Stay Busy AFBoredom = fake hunger.Plan activities, work, cleaning, shopping, plotting your world domination — whatever keeps your mind off food.

4. Break Up With the KitchenDon’t torture yourself by hanging around food smells or staring into the fridge like it’s going to tell you secrets.Out of sight, out of mind.

5. Watch the ElectrolytesIf you feel dizzy, weak, or like you might slap somebody... you’re probably low on electrolytes.Magnesium, sodium, potassium — they’re crucial.You can sip bone broth, take supplements, or just sprinkle salt in your water like the queen you are.

6. Ride the Hunger WavesHunger comes in waves — it doesn’t just grow until you spontaneously combust.If you stay busy and sip water/tea, the wave will pass in like 10–15 minutes.

7. Get Your Mind Right Before You StartFasting is mostly mental.Hype yourself up beforehand. Remind yourself:

• "I'm healing."

• "This is temporary."

• "I’m stronger than a snack craving."

8. Gentle Movement HelpsA light walk, some yoga, or stretching can boost your mood and burn fat without draining your energy.(Save the hardcore workouts for after you eat though.)

9. Listen to Your Body (Not Your Excuses)There’s a difference between "I’m uncomfortable" and "I’m actually in trouble."Push through discomfort.But if you feel legit faint, sick, or off — it’s okay to break the fast. You still win because you showed up for yourself.

10. Celebrate Every WinGirl, even 16 hours, 20 hours, or 24 hours is a MAJOR flex.Don't let anyone tell you different.You’re literally burning fat and healing your body just by NOT doing something.Icon behavior.

Bonus Tip:

Plan your refeed meal ahead of time — because after a long fast, you deserve a nutrient-packed glow-up meal, not a regretful binge.
