❄️Feeling drained, unmotivated, or just “off” this winter? You’re not alone, and it’s not laziness. Winter fatigue is real, and it’s often caused by changes in your internal chemistry, not a lack of willpower.

As the days get shorter, routines shift, and sunlight decreases, our hormones; dopamine, serotonin, oxytocin, and endorphins take a hit. These “feel-good” hormones control your energy, mood, stress response, and motivation.

The good news? Hormones are malleable. With intentional, science-backed habits, you can restore energy, stabilize mood, and beat the winter blues naturally.

Here’s how to work with your biology instead of against it:

1️⃣ Boost Dopamine – The “reward chemical” fuels motivation and focus. Celebrate small wins daily, try a new hobby, or set achievable goals. Every success triggers dopamine and makes future action easier.

2️⃣ Support Serotonin – This mood stabilizer helps regulate sleep, appetite, and emotional balance. Prioritize quality sleep, get daily sunlight, and eat serotonin-supporting foods like turkey, eggs, and seeds.

3️⃣ Increase Oxytocin – The “love hormone” strengthens connection and trust. Engage in physical touch, shared laughter, or bonding with loved ones and pets to naturally raise oxytocin and reduce stress.

4️⃣ Activate Endorphins – These natural stress relievers reduce pain and increase happiness. Exercise, dance, music, or even moments of challenge followed by relief release endorphins and boost resilience.

Other simple, repeatable habits to help fight winter fatigue and seasonal affective changes include:

🚶‍♀️Daily movement: walking, HIIT, yoga

🧘‍♀️Deep breathing or meditation

👯 Social connection and meaningful interactions

💆‍♀️ Massage, acupuncture, or self-care rituals

🥕 Whole foods that support neurotransmitter function

☀️ Morning sunlight or light therapy

Start small: pick 2–3 habits today and layer them in. Over time, your energy, mood, and resilience will improve, and winter won’t feel like such a struggle.

3 Nutrition Habits to Focus on This Year 🌟

If you’re looking to feel more energized, support your health, and create sustainable eating habits, start with these three simple but powerful nutrition habits:

1️⃣ Hydration 💧
Water is essential for every system in your body. fFrom digestion and circulation to energy production and brain function. Staying properly hydrated can improve focus, reduce fatigue, and even help with appetite control. A good rule of thumb: aim for at least half your body weight in ounces of water each day, and remember that herbal teas and water-rich foods count too!

2️⃣ Blood Sugar Balance 🍎🥦
Keeping your blood sugar stable helps prevent energy crashes, mood swings, and cravings. Focus on pairing carbohydrates with protein and healthy fats, choosing fiber-rich fruits and vegetables, and spacing meals evenly throughout the day. This can help your body use energy more efficiently and reduce those mid-afternoon crashes.

3️⃣ Increasing Protein & Fiber 🥚🥗
Protein supports muscle repair, keeps you full longer, and helps regulate hormones. Fiber promotes healthy digestion, supports gut health, and keeps you feeling satisfied. Incorporate a variety of sources like lean meats, beans, lentils, whole grains, nuts, seeds, fruits, and vegetables into your meals.

Ready to step up your health this year? In my CGM LEAN program I will teach you how to feel your best without tracking food, but instead giving you personalized insight into your blood sugar response using a Continuous Glucose Monitor (CGM).

Your body is talking—are you listening? 📊✨

In CGM LEAN, you’ll wear a Continuous Glucose Monitor and discover exactly how YOUR body responds to food in real-time. No more guessing, no more tracking macros—just personalized insight into what’s really happening inside.

Here’s what you’ll learn:
Which foods spike your blood sugar (and secretly store fat)
How YOUR unique body processes carbs, protein, and meals
The simple adjustments that lower insulin and unlock fat-burning
Why you’ve been working so hard with little progress
How to optimize your meals without obsessive tracking

When insulin is elevated, fat loss stops. Period. But here’s the game-changer: everyone’s insulin response is different. That’s why the CGM shows you the foods that work FOR your body—not against it.

This isn’t another diet. It’s data-driven transformation with daily coaching, accountability, and support from me!

The next session starts MONDAY, and spots are filling fast.

Your body NEEDS salt to thrive—here’s why the low-sodium myth is doing more harm than good.

Starving yourself isn’t the shortcut you think it is. 🚫

It’s usually the reason progress stalls. Your metabolism doesn’t need less food, it needs the right fuel, consistency, and strength.

💪 Protein: Protein boosts metabolism through the thermic effect of food and helps you build/maintain muscle—the engine of your metabolism.
🥬 Fiber: Fiber stabilizes blood sugar, supports digestion, and keeps hunger regulated so your metabolism can stay consistent.
🏋️‍♀️ Strength train: Muscle burns more at rest. More muscle = higher metabolism, even when you’re not working out.
🍽️ Consistent meals: When you skip meals, your energy is more likely to crash which leads to a slowed metabolic response.Regular meals keep your metabolism steady and supported.

These small daily habits that create a big metabolic shift over time.

If you’re tired of guessing what to eat or feeling stuck, my CGM LEAN program teaches you how to fuel your body the right way — with real data, not restriction.

This recipe makes alot of food! Great to eat for dinner one night and then use for leftovers at lunch the rest of the week.

1 lb pork sausage, cooked and drained
1 lb LEAN ground beef, cooked
4 cup cole slaw mix
1 cup shredded carrots
1 cup shredded purple cabbage
Tamari
2 packages of ramen noodles ( you could also sub any gluten free noddles)

Cook your sausage and ground beef, then add your slaw mix, carrots and purple cabbage and cook more. Add tamari and or teriyaki sauce to taste. While that cooks, boil water and cook your ramen noodles. I used one pack in the video but the recipe does need two packs. Throw out the seasoning from the noodle packs.

Once the noodles are cooked add them to the meat and veggie mix and enjoy!

Here’s the brutal truth: when you’re insulin resistant, your body can’t use carbs for energy anymore. Every piece of bread, every banana, every “healthy” granola bar gets converted straight to belly fat.

Your muscle cells are resistant to insulin, so they reject the glucose. But your fat cells? They’re ALWAYS ready to accept it. So everything you eat bypasses your muscles and goes directly to fat storage around your middle.

This is why you can eat the same amount of calories as your friend and she stays lean while you gain weight. Her insulin is working. Yours isn’t.

The fix: Reverse your insulin resistance by eating low-carb/high-protein for 30 days, lifting weights to build insulin-sensitive muscle, walking after meals to clear glucose, and getting 8 hours of sleep to regulate hormones.

You’re not eating too much. Your hormones are broken. Fix the hormones, lose the fat.

Stop guessing why you can’t lose weight. My CGM LEAN program gives you real-time data on how YOUR body processes food, so you can make changes that actually work for your metabolism and fixes your blood sugar issue. No calorie counting, just personalized insights that lead to real results. Comment INFO below and I will send you all the details.
