One of the biggest keys to getting Fit for Life, especially for women over 30, is eating enough protein. It’s essential for building muscle, burning fat (aka body recomposition), and combating muscle loss as we age.

But let’s be real—hitting that goal consistently can be a challenge. That’s why I created this FREE 1-Day Meal Plan to show you exactly how simple and delicious high-protein eating can be! Plus, every meal is high in fiber, which is not only great for keeping you full but also vital for optimal digestion and gut health.

1.High in protein to support muscle building & fat loss 2.High in fiber to promote better digestion & gut health 3. No complicated recipes—just real, satisfying food

This is What Consistency Looks Like

37 years old. Two kids. More energy, more confidence, and in the best shape of my life—stronger than I was in my 20s.

Hi, I'm Mariuxi De Souza, a Certified Personal Trainer and Nutrition Coach, founder of VIVA Fitness and The Fit for Life method.

I created every guide, every workout program, and every nutrition plan based on what actually works—for real women with full plates. No extremes. No fads. Just sustainable, smart strategies that support your hormones, your lifestyle, and your long-term results.

If you're over 35, you’ve probably experienced it—you can’t just eat whatever, stop moving your body, and bounce back without getting taxed by your health like you used to. And that’s exactly why now is the time to be more intentional—with how you train, how you fuel your body, and how you show up for yourself.

That’s exactly why I created the Fit for Life Method—a simple, effective approach to training and nourishment that helps you feel strong, capable, and in control of your health as you age.

This is the exact approach I’ve used to maintain my results for the past five years and the same one that's helped other women feel stronger, look leaner, and feel more energized—without sacrificing their sanity.

I feel better in my body now than I ever did in my 20s. And I can't wait for you to experience the same!
