how intermittent fasting actually works (and why I swear by it)

Why I tried intermittent fasting (and why it stuck)

Let me set the scene: I’m a mom of two, working full-time, and my idea of a "dinner date" was eating cold pizza at 9:30 p.m. while scrolling through work emails. Needless to say, my energy levels were in the gutter, my jeans were screaming for mercy, and I was tired of feeling like a human sloth.

Then one day, after Googling "how to stop eating like a garbage disposal," I stumbled across intermittent fasting. At first, I scoffed—"Skipping breakfast? That’s for people who don’t have kids or jobs." But after a few weeks of forcing myself to eat at 1 p.m. instead of noon, I noticed something wild: I wasn’t starving. I wasn’t cranky. And somehow, the scale started moving. So, I leaned in.

Turns out, fasting isn’t about suffering—it’s about strategic eating. And for a busy mom who can’t spend hours meal prepping or counting every calorie, it’s been a lifesaver.

What even is intermittent fasting?

Intermittent fasting (IF) isn’t a diet. It’s a pattern of eating where you cycle between periods of eating and fasting. No special foods, no magic shakes—just timing. The most common methods are:

• 16:8: Fast for 16 hours, eat within an 8-hour window (e.g., stop eating at 8 p.m., eat again at 12 p.m. the next day).
• 14:10: A gentler version—fast for 14 hours, eat within a 10-hour window. Perfect if you’re not ready to give up breakfast.
• 5:2: Eat normally for 5 days, then slash calories to 500-600 for 2 days. (I tried this once. It made me hangry. Never again.)

I landed on 16:8 because it fit my schedule. No breakfast? No problem. I’d grab a coffee (black, because milk is basically dessert), then eat my first meal around noon. By 8 p.m., I’d be done—no late-night fridge raids.

What happens to your body when you fast

Here’s the science-y part, but I’ll keep it simple: When you stop eating, your body burns through glycogen (stored carbs) first. After about 12 hours, it switches to burning fat for fuel. That’s called ketosis, and it’s why IF can help with weight loss.

But it’s not just about fat burning. Fasting also:

• Lowers insulin levels, which helps your body tap into fat stores.
• Boosts human growth hormone (HGH), which helps preserve muscle.

I won’t lie—I was skeptical until I saw the numbers. After three months of 16:8, I’d lost 12 pounds without changing what I ate (much). My energy? Up. My cravings? Down. And my wallet? Thicker, because I wasn’t buying as many snacks.

How to make intermittent fasting work for YOU

If you’re thinking, "This sounds great, but I can’t go 16 hours without food," you’re not alone. Here’s how I made it work:

Start slow

I didn’t jump straight to 16:8. First, I tried 12:12 (fast for 12 hours, eat for 12). That meant no snacking after 8 p.m. It was easy, and I didn’t feel deprived. Then I stretched it to 14:10, and finally 16:8. Baby steps matter.

Hydrate like it’s your job

Water, herbal tea, black coffee—drink up. Dehydration masquerades as hunger, and I’ve definitely chugged a glass of water only to realize I wasn’t actually hungry. Pro tip: Add a pinch of salt to your water if you’re feeling sluggish. Electrolytes help.

Don’t overcomplicate meals

I used to stress over making "perfect" meals. Now? I keep it simple:

• Lunch: Grilled chicken + roasted veggies + a drizzle of olive oil.
• Dinner: Salmon + quinoa + steamed broccoli.
• Snacks (if needed): Greek yogurt + berries or a handful of almonds.

No fancy recipes. No guilt if it’s just leftovers. The goal is to eat enough to feel satisfied, not stuffed.

Listen to your body

Some days, I’m ravenous by noon. Other days, I could wait until 2 p.m. without issue. IF isn’t about forcing a rigid schedule—it’s about finding what works for your body. If you’re shaky or dizzy, eat. Don’t push through it.

What I wish I’d known before starting

Looking back, here’s the stuff I wish someone had told me:

You’ll have "off" days

There was this one Tuesday where I ate a sleeve of crackers at 10 a.m. because I was hangry. Then I felt guilty. Then I ate more crackers. It was a vicious cycle. The lesson? Fasting isn’t all-or-nothing. If you slip up, just reset at your next meal.

It’s not a free pass to eat junk

I thought I could eat whatever I wanted during my eating window. Spoiler: I couldn’t. A bag of chips at lunch led to a sugar crash by 3 p.m., and suddenly I was fantasizing about a nap (or a nap and a cookie). Focus on protein, fiber, and healthy fats to stay full.

Sleep matters more than you think

If I’m up until midnight scrolling on my phone, I’m starving by 9 a.m. the next day. Poor sleep = more hunger hormones. Aim for 7-8 hours, and you’ll have an easier time sticking to your fasting window.

Does intermittent fasting work for everyone?

Short answer: No. Long answer: It depends. If you have a history of disordered eating, IF might not be right for you. If you’re pregnant, breastfeeding, or have certain medical conditions, check with your doctor first. And if you’re a teenager? Probably not the best idea.

But for most people? It’s worth a try. The research backs it up:

• A review in the New England Journal of Medicine found that fasting can improve metabolic health and aid weight loss.
• A study in PMC showed that intermittent fasting can reduce body weight and improve insulin sensitivity.
• Harvard Health notes that IF may help with weight loss and longevity.

That said, it’s not magic. You still need to eat real food and move your body. But for me? It was the missing piece.

FAQ: Your burning questions answered

Will I be starving all the time?

Not if you ease into it. The first few days might be tough, but your body adapts. I promise. If you’re truly miserable after a week, try a shorter fasting window.

Can I work out while fasting?

Yes! I lift weights fasted in the morning (black coffee helps). But if you’re doing intense cardio, you might want to eat something light first. Listen to your body.

What if I’m a night owl?

Try a later eating window. If you naturally eat dinner at 9 p.m., shift to 12 p.m. to 8 p.m. or 1 p.m. to 9 p.m. The key is consistency—pick a window and stick with it for at least a few weeks.

Key takeaways

• Intermittent fasting is about when you eat, not what you eat.
• Start slow—12:12 or 14:10 is a great place to begin.
• Hydration and sleep make a huge difference in how you feel.
• It’s not a free pass to eat junk food. Focus on protein, fiber, and healthy fats.
• Give it at least 3-4 weeks before deciding if it’s right for you.

For me, intermittent fasting wasn’t about losing weight—it was about feeling better. More energy. Less stress about food. And yeah, a smaller waistline. If you’re curious, give it a shot. Just don’t expect miracles overnight. And for the love of all things holy, don’t tell your kids you’re "fasting" unless you want them to ask why you’re not eating their chicken nuggets.
