I remember standing in my kitchen at 6 AM, staring at my usual bowl of cereal, and making a decision that would change everything. What if I just… didn’t eat breakfast? Sounds crazy, right? Especially after years of hearing “breakfast is the most important meal of the day.” But that simple shift—waiting until noon to eat my first meal—helped me lose 45 pounds without counting a single calorie or giving up my favorite foods. Today, I’m going to share exactly how intermittent fasting works, whether it’s right for you, and the science-backed strategies that actually move the needle.
Intermittent fasting (IF) has gained popularity as a weight loss strategy, but is it right for everyone? IF involves cycling between periods of eating and voluntary fasting on a regular schedule. There are several different approaches to IF, including the 16/8 method, the 5:2 diet, and alternate-day fasting. Each method has its own set of rules and guidelines. Understanding these different approaches is crucial before deciding if IF is a good fit for you. It’s important to consider your lifestyle, health conditions, and personal preferences.
One of the main benefits of IF is its potential to promote weight loss by reducing calorie intake and improving insulin sensitivity. Studies have shown that IF can lead to significant weight loss and improvements in metabolic health markers. However, IF is not without its drawbacks. Some people may experience side effects such as hunger, fatigue, and irritability. It’s also important to note that IF may not be suitable for everyone, especially those with certain medical conditions or a history of eating disorders. Consulting with a healthcare professional is essential before starting any new diet or fasting regimen.
Ultimately, the decision of whether or not to try intermittent fasting is a personal one. While IF can be an effective weight loss strategy for some, it’s not a magic bullet. It’s important to approach IF with realistic expectations and to listen to your body. If you experience any negative side effects, it’s best to stop and re-evaluate. Remember, sustainable weight loss is about finding a balanced approach that works for you in the long term. Consider your individual needs and consult with a healthcare professional to determine if IF is a safe and appropriate option for you.

MY RECOMMENDATION: If you’re just starting, begin with 14:10 (14-hour fast, 10-hour eating window) for the first week, then progress to 16:8. Don’t jump straight into extreme protocols—consistency beats intensity every time.
==========================================
What Your Day Actually Looks Like
Let me walk you through exactly how to structure your day with the 16:8 protocol (my personal favorite for busy moms):
THE MORNING ROUTINE (Fasting Hours):
7:00 AM – Wake up, drink black coffee or green tea (zero calories)
8:00 AM – Hydrate with 16-24 oz of water with a squeeze of lemon
9:00 AM – If hungry, have another black coffee or sparkling water
10:00 AM – Busy yourself with work, errands, or exercise
11:30 AM – Drink final glass of water before your eating window
THE EATING WINDOW (12:00 PM – 8:00 PM):
12:00 PM (First Meal) – Protein + healthy fats + vegetables
Examples:
- Greek yogurt bowl with berries, almonds, and chia seeds
- Leftover chicken with avocado and mixed greens
- Salmon with roasted vegetables
3:00 PM (Snack – Optional) – Handful of nuts or protein shake
6:30 PM (Dinner) – Balanced meal with family
Examples:
- Grilled salmon, roasted vegetables, quinoa
- Turkey meatballs with zucchini noodles
- Chicken stir-fry with brown rice
7:30 PM (Dessert – If Desired) – Small portion, enjoyed mindfully
Examples:
- Dark chocolate (2-3 squares)
- Greek yogurt with honey
- Fresh berries with whipped cream
8:00 PM – Eating window closes—no more food until noon tomorrow
PRO TIP: The exact timing is flexible. If you prefer eating 1 PM – 9 PM because of your schedule, that works perfectly too. The key is maintaining the 16-hour fasting window consistently.

5 Mistakes That Sabotage Your IF Results
MISTAKE #1: Breaking Your Fast with Junk Food
Just because you’ve fasted for 16 hours doesn’t mean you can eat anything. Your first meal should be nutrient-dense: protein, healthy fats, and fiber.
❌ Bad first meal: Sugary cereal, pastries, processed foods
✅ Good first meal: Eggs with avocado and vegetables, Greek yogurt with nuts
MISTAKE #2: Not Drinking Enough Water
Dehydration is the #1 reason people feel terrible during fasting. Aim for 80-100 oz of water daily.
MISTAKE #3: Fasting for Too Long, Too Soon
Your body needs time to adapt. Start with a 12-14 hour fast and gradually extend it over 2-3 weeks.
MISTAKE #4: Ignoring Hunger Signals vs. Cravings
There’s a difference between true hunger and habitual snacking. If you’re genuinely hungry, eat. If it’s boredom or routine, distract yourself for 15 minutes.
MISTAKE #5: Skipping Strength Training
Fasting without exercise can lead to muscle loss. Do resistance training 2-3x per week to preserve lean mass while losing fat.
==========================================
Intermittent fasting isn’t a magic bullet, but it’s the closest thing I’ve found to sustainable fat loss without extreme restriction.
Here’s the truth: The first week might feel hard. You’ll be hungry at times you’re used to eating. Your body is adjusting to using fat for fuel instead of relying on constant food intake.
But by week two, something shifts. You’ll have more mental clarity. Your energy stabilizes. The scale starts moving. And most importantly, you’ll realize you’ve been overthinking food for years.
YOUR NEXT STEPS:
- Choose your protocol (I recommend starting with 16:8)
- Download a fasting tracker app (see recommendations above)
- Plan your first eating window around your schedule
- Stay hydrated and be patient with yourself
- Track your progress beyond just the scale (energy, sleep, mood)
