Walking vs Running: Which Exercise Is Best for Fat Loss Over 40?

While I’ve been in Puerto Vallarta, I decided to test something I’ve always wondered:
How different is the calorie burn between regular walking, interval walking, fast walking, and Zone 2 running?

So, for four days, I set my timer for around 30 minutes and did each style of movement:

• Regular walking pace
• Interval walking
• Faster, power-walking pace
• Zone 2 running

And the results surprised me in the best way.

🏃‍♀️ The Results:

Even though I love running (it’s my therapy!), the calorie burn between walking styles and running wasn’t dramatically different.

In fact…

✨ Faster walking and interval walking gave me almost the same calorie burn as running — without the joint stress, recovery time, or exhaustion afterwards.

This experiment reminded me of something important for women over 40:
Why Walking Is So Powerful for Fat Loss

Walking is one of the most underrated forms of exercise. And for fat loss over 40, it’s actually ideal.

Here’s why:

✔ 1. It supports hormone balance

High-intensity workouts spike cortisol. Walking, especially Zone 1–2, reduces it — helping minimize cravings and overeating.

✔ 2. It burns calories without burnout

Because it’s low-impact, you can walk daily… which means you burn more overall across a week.

✔ 3. It’s gentle on joints

Especially important for those of us with knee arthritis or past injuries.

✔ 4. It boosts cardiovascular fitness

Zone 2 walking and running both strengthen your heart — the pace doesn’t need to be extreme.

✔ 5. It’s sustainable

Consistency beats intensity every single time.

The Biggest Lesson?

👉 Walking “counts.”
👉 Walking supports fat loss.
👉 Walking is absolutely enough.

And if you love running, fantastic — keep running.
But you don’t need high-intensity cardio to make progress. Most days, a simple walk wins.
