The 30/30 Program

with Matthea Rentea MD


Master the art of breaking old habits and embracing change to break through a weight loss plateau!

In just 4 weeks, you’ll rediscover your joy for food and movement, while cultivating a more flexible, open mindset that supports *lasting* change.



Welcome! I'm Dr. Matthea Rentea MD, a board certified Internal Medicine and Obesity Medicine physician, diplomate of the American Board of Obesity Medicine, and advanced certified weight loss coach.

I know firsthand the challenges people face when losing weight and keeping it off, not just from my experience of working closely with patients, but from my own lifelong struggle with weight management.

Failure to achieve a certain number on the scale is often seen as a moral character flaw in our culture. But this mindset overlooks a number of complex factors influencing our weight. And as someone who has witnessed the emotional and physical toll of extreme diets and unrealistic expectations, I believe it’s time to shift our focus.

The first time I ever tried to lose weight was in college. I lost around 60 lbs by massively restricting calories and hitting the gym for two hours a day. But I constantly felt like I was going to lose control and I knew I couldn’t live the rest of my life like that.


Now, I understand that there’s so much more to health than arbitrary numbers on a scale.


That’s why I created the 30/30 Program—to move beyond unrealistic goals, redefine success, and focus on what truly matters: feeling energized, mentally strong, and able to enjoy a life without restriction.


I’ve seen too many people let down by quick fixes and empty promises. I wanted to offer something different—something that teaches you how to master the art of building sustainable habits in a short time, and lasts for the long haul. That’s the heart of The 30/30 Program.


Integrating these strategies alongside any medical treatment you may need, will mean you can stop obsessing over the scale and let your body naturally decide where it’s willing to go.

So, are you ready to join a health program where success is *inevitable*?


Want to join a health program where success is measured by more than just numbers on a scale?

Are you:
  • Struggling to find a balance between health goals and the demands of daily life?
  • Bored of repeating the same tactics and strategies, without making any real progress?
  • Feeling stuck in a rut with your food and exercise routine, unable to break out of a weight loss plateau?
  • Constantly searching for the latest expert or trend, hoping for a solution that will finally work?
  • Measuring your success solely by the number on the scale, feeling discouraged when it doesn't meet your expectations?
  • Frustrated with your progress, wondering why this journey is so hard and you're the only one not making progress?

Human beings are creatures of habit. The 30/30 program offers a refreshing way to break out of old patterns and discover what truly works for you.
Jumpstart your journey with 30 days of exploring 30 different fruits and vegetables, engaging in 30 movement sessions, and prioritizing 30 grams of protein three times a day. Designed to set you up for success over the next four months, this program encourages experimentation and flexibility, ensuring that every step forward is a step towards discovering your optimal health and well-being.
With a focus on learning and adaptation, there is no way to fail—only opportunities to learn to connect with and trust your body again.
Here’s what you’ll learn in 4 weeks:
Week 1: How to Improve Your Gut Microbiome
Learn how to enhance your gut health through a diverse range of fruits, vegetables, nuts, and seeds. These foods are rich in fiber, antioxidants, and essential nutrients that support a healthy microbiome, aiding digestion and overall well-being.
Week 2: How to Find Joy in Movement
Explore different forms of movement that bring you happiness and satisfaction, prioritizing emotional regulation, maintaining muscle strength, and promoting longevity, while consciously avoiding a focus on weight loss.
Week 3: How to Prioritize Protein for Satiety, Muscle Health, and Metabolic Rate
Discover the importance of prioritizing protein intake, aiming for 30 grams, three times a day. Protein plays a critical role in promoting satiety, preserving muscle mass, and boosting metabolic rate. Learn how to incorporate lean sources of protein such as poultry, fish, legumes, and tofu into your meals to support these essential functions throughout your day.
Week 4: How to Build your Roadmap to Success
Reflect on your 30/30 Program journey and outline a clear plan for the next four months. Set achievable goals, establish actionable steps, and create a supportive environment to maintain your progress in health and wellness. This roadmap will guide you towards sustainable habits and long-term success.

  • Ready to put in the effort and actively engage.

  • Open to exploring new ideas and approaches to health and wellness.

Curious about what members of the Rentea Metabolic Community are raving about? 


Here’s a glimpse into their experiences:

7-Day Guarantee

As someone who has struggled with weight their whole life, I’ve invested in a lot of programs myself that have not been a good fit for my personal health goals. And I want you to feel that The 30/30 Program is exactly the right fit for you. If within the first week of the program, you discover it’s not a good fit, please email [email protected] to discuss a refund. 

P.s. I get it. Investing in yourself is scary! But here’s the truth: if you want a different output, you have to change the input.




What if I’ve never done a small group coaching program before?

Don’t panic! I do a Welcome Call for every group coaching program and during the Welcome Call, I lay out the community rules, some best practices, and strategies for how to get the most out of the program and the group experience. Every group is a little different, and we always have a great time learning from each other and growing together.


If I’m not a patient of yours, can I still join?

Yes, this is a general program. There is NO medical advice being given during this program. By joining this program you are NOT establishing medical care with me.


What if I can’t make it live to the calls?

No problem. The call replays will be uploaded to the course site within 24 hours for you to access at any time during the program. In addition, you will have access to all recorded calls in a podcast format so you can listen on-the-go! You will be able to ask questions prior to the calls if you want them answered live, or you can ask them in the community WhatsApp group where I will be answering them often. 


How long do I have access to the materials?

All handouts are available for you to download for your personal use for one month after the program ends. The WhatsApp group will end the week the program ends. 


What is the time commitment?

My philosophy is always: take what works and drop the rest. At a minimum there is a 90-minute live call per week that you can attend live or catch the replay for. There will be recommended goals and tasks for the week but you can see how much of that you are able to do. The community aspect while helpful is not mandatory. 


Will this program be offered again? 

The 30/30 Program is held three times a year in January, April, and September. When you are on a weight loss journey, you are constantly reinventing yourself and need new tools and inspiration in order to adapt along the way.  By incorporating small change “sprints” into your year, you will overcome metabolic adaptation, which causes weight loss plateaus,  and cultivate a more flexible, open mindset, which opens you up to becoming the next version of you!
